Comprehensive spatial differentiation of territorial communities: case of Zhytomyr region 地域群落的综合空间分异——以日托米尔地区为例
M. Ilina, Yulia Shpyliova
Goal of the research. In 2014 in Ukraine the massive decentralization reform has been initiated. It aimed to transform many single administrative units into much larger territorial communities. Spatial differentiation of the newly consolidated communities by values of their proximity to large cities and urban areas within the case of Zhytomyr region is the goal of the article.Methods of the research. Zhytomyr region is one of the most successful in Ukraine on implementation of the administrative reform, decentralization and best practices of the communities’ integration. The region had been selected for the in-depth study taking into account its central location, economic situation and the environment. Data of the State statistics agency of Ukraine, governmental and non-governmental institutions and Google Maps was applied to conduct the research and identify the territories’ groups.The research results. Aiming to perform spatial typology of the newly consolidated territorial communities we differentiated them depending on their proximity to cities and other urban centers firstly. Consequently three types of the communities have been defined: neighboring, relatively remote, and faraway. Distance of the communities to urban centers relates with their area and people size: the closer a territorial unit is located to the city, the smaller is its area and population. Other words, the proximity of a community to the city determines its economic capacity much more than its population and area. Statistical relations between duration of the communities’ consolidation and their spatial types prove the faraway and relatively remote communities have been united earlier than the neighboring. Taking into account the average number of settlements belonging to the one consolidated community it is revealed the closer to the regional center communities include less number of settlements. Two-dimensional classification of the communities by their proximity to regional and rayon centers confirms communities located close to cities and towns have better opportunities for the development.Novelty of the research results. The presented methodological approach to comprehensive differentiation of the territorial communities can be applied to identify their challenges, threats and prospects. For this purpose, the algorithm is proposed which combines indicators of spatial differentiation of rural areas, their economic status, social infrastructure, and the environment.Practical significance. The proposed methodological approach to spatial differentiation of rural territories is aimed assisting representatives of the communities, local self-government bodies and state authorities to develop and refine local strategies and programs, update coherent plans and identify target communities for certain projects.
研究的目的。2014年,乌克兰启动了大规模的权力下放改革。它旨在将许多单一的行政单位转变为更大的领土社区。在日托米尔地区的情况下,通过与大城市和城市地区的接近程度来确定新合并社区的空间差异是本文的目标。研究方法。日托米尔地区是乌克兰执行行政改革、权力下放和社区一体化最佳做法最成功的地区之一。考虑到该区域的中心位置、经济状况和环境,选择该区域进行深入研究。乌克兰国家统计机构、政府和非政府机构以及谷歌Maps的数据被用于进行研究和确定领土群体。研究成果。为了对新合并的领土社区进行空间类型学,我们首先根据它们与城市和其他城市中心的接近程度对它们进行区分。因此,社区被定义为三种类型:邻近的、相对较远的和遥远的。社区到城市中心的距离与其面积和人口规模有关:一个领土单位离城市越近,其面积和人口就越少。换句话说,一个社区与城市的接近程度比其人口和面积更能决定其经济能力。群落整合时间与其空间类型的统计关系表明,距离较远和相对较远的群落比邻近的群落更早地统一。考虑到属于一个合并社区的平均定居点数量,发现越靠近区域中心的社区包括较少的定居点数量。根据靠近区域中心和人造丝中心对社区进行二维分类,证实靠近城镇的社区有更好的发展机会。研究成果的新颖性。所提出的全面区分领土社区的方法方法可用于确定其挑战、威胁和前景。为此,提出了结合农村空间分异、农村经济状况、农村社会基础设施、农村环境等指标的农村空间分异算法。现实意义。拟议的农村地区空间分异方法旨在协助社区代表、地方自治机构和国家当局制定和完善地方战略和方案,更新连贯的计划,并确定某些项目的目标社区。

T. Safranov, Halyna Katerusha, Оlena Katerusha, K. Yaraei
Formulation of the problem. One of the main manifestations of regional climate changes in Ukraine on the background of global warming is substantial rise of air temperature and increasing of extreme weather conditions. Therefore heat waves became a concern. Detection of heat waves and their physical and statistical characteristics on the territory of Ukraine was done by many researchers only during warm period of the year and on the basis of fact data. But it's interesting to find out what happens in this context during cold period as well because heat waves affect not only human health but also agriculture, transportation etc throughout the year. Besides in order to overcome negative consequences and for adaptation of people for climate changes prognostic values of meteorological indices, in particular air temperature according to modern climate change scenarios.Review of previous publications. Consequences of thermal waves impact on population health is being studied in different countries of the world and in the main medical data base PubMed there are more than 1000 publications in this branch of research. But still there is no universal definition of heat waves which could be used as criteria for detecting this anomaly in all the researches. This can be explained that depending on challenges of scientific research or practical service of household activity waves of certain intensity or duration can be the most interesting. Purpose. The aim of this work is detection of heat waves on the basis of actual and scenario data and analysis of their physical and statistical characteristics and dynamics until 2050.Methods. Heat waves were detected on the base of actual data and model ranges by low (RCP 2.6), medium (RCP 4.5), high (RCP 8.5) levels of greenhouse gases emissions and also there were analyzed their physical and statistical characteristics and dynamics until 2050 in different regions of Ukraine.Results. The smallest annual number of heat waves is recorded in the south of Ukraine and the maximum heat wave duration is approximately the same at all the research stations (Uzhgorod, Kharkiv, Odessa). According to all climate change trends that were used, the greatest number of heat waves in the next thirty years is expected in the south of Ukraine, with a maximum in the cold season (October-April). The intensity of heat waves, expressed by the cumulative temperature, during the cold period slightly exceeds this index during the warm period in the west and north-east and substantially exceeds it in the south, and heat waves of the same duration can have quite different intensities.Conclusions. In the west of Ukraine, there is a trend of increasing the number of heat waves and their duration over the studied period by decades, in the northeast and south - these indicators have fluctuated. It was discovered that in all regions, according to actual data, heat waves of 6-9 days have the highest recurrence (82% of total amount of heat waves
问题的表述。在全球变暖背景下,乌克兰区域气候变化的主要表现之一是气温大幅上升,极端天气现象增多。因此,热浪成为人们关注的问题。乌克兰领土上的热浪及其物理和统计特征的探测是由许多研究人员仅在一年中温暖的时期根据事实数据完成的。但有趣的是,在寒冷时期也会发生这种情况,因为热浪不仅影响人类健康,还影响全年的农业、交通等。此外,为了克服负面影响和使人们适应气候变化的气象指数的预测价值,特别是根据现代气候变化情景的气温。回顾以前的出版物。世界各国正在研究热波对人口健康影响的后果,在主要的医学数据库PubMed中,这一研究分支有1000多份出版物。但是在所有的研究中仍然没有一个统一的热浪定义,可以作为探测这种异常的标准。这可以解释为,根据科学研究或实际服务的挑战,一定强度或持续时间的家庭活动波可能是最有趣的。目的。这项工作的目的是在实际和情景数据的基础上探测热浪,并分析其物理和统计特征和动态,直到2050年。基于实际数据和模式范围,对乌克兰不同地区低(RCP 2.6)、中(RCP 4.5)、高(RCP 8.5)温室气体排放水平的热浪进行了探测,并分析了其物理和统计特征以及到2050年的动态变化。乌克兰南部记录的年热浪次数最少,所有研究站(乌日哥罗德、哈尔科夫、敖德萨)的最大热浪持续时间大致相同。根据所使用的所有气候变化趋势,预计未来三十年热浪次数最多的地区是乌克兰南部,在寒冷季节(10月至4月)达到最大值。以积温表示的热浪强度在西部和东北部偏冷期略高于该指数,而在南部则大大超过该指数,并且相同持续时间的热浪强度可能相差很大。在乌克兰西部,在所研究的几十年期间,热浪的次数和持续时间有增加的趋势,在东北部和南部,这些指标有所波动。研究发现,在所有地区,根据实际数据,6-9天的热浪发生率最高(占全年热浪总量的82%);根据RCP2.6情景,其在该国南部的复发率将降至最低(高达52%)。根据所有使用到2050年的气候变化趋势,预计乌克兰南部的热浪次数最多,在寒冷季节(10月至4月)达到最大值。乌克兰所有地区,尤其是南部地区,寒期的热浪强度都高于暖期。

Assessment of environmental risks of underground transport infrastructure development by BOCR method 基于BOCR方法的地下交通基础设施建设环境风险评价
N. Pankratova, N. Nedashkovskaya, H. Haiko, V. Biletskyi
Formulation of the problem. Solving the problems of urban transport communications, in particular the constantly growing intensity of automobile traffic in megalopolises, is one of the main directions of minimizing the environmental and man-made risks of the urban environment. Global concepts of greening large cities pay considerable attention to the possibilities of underground space to take on the functions of the most dangerous and risky surface objects and communications, since the impact of any underground object on the environment is much lower (than similar on the surface) and can be better controlled.At the same time, planning for the development of underground transport infrastructure should be based on a systematic methodology and tools for analyzing complex systems.Purpose. It consists in the use of system tools (BOCR method - criteria of benefits, opportunities, costs and risks) for planning underground transport infrastructure of large cities to ensure minimization of environmental and man-made risks of urban space and prioritization for the construction of road tunnels (for example, the General Plan of the Kiev city).Methodology. A methodology and decision support toolkit for calculating the priorities of alternatives based on hierarchical and network criteria models are proposed. The modified BOCR method developed by the authors (N. Pankratova, N.I. Nedashkovskaya) was applied to assess decision alternatives taking into account benefits, costs, opportunities and risks.Results. System models of two road tunnels, according to the General plan of the Kiev city until 2025 were developed. Assessment of the models using the BOCR method (criteria for benefits, opportunities, costs and risks) was performed. The priorities of alternatives for tunnels' routes aggregated over a network of parameters and a reasonably expedient sequence of their construction were calculated according to the criteria for reducing the environmental and man-made risks of the urbanized space.Scientific novelty. For the first time, the target function of the system model for the development of underground infrastructure in large cities is to minimize the environmental and man-made risks of urban space. The capabilities of the modified BOCR method have been expanded and two alternative tunnel track models have been successfully tested.Practical significance. The research methods and results provide investors, city state administrations and public organizations with an effective toolkit for assessing the priority of the construction of underground urban facilities to regulate urban development in order to improve environmental standards and the safety of life in megacities.
问题的表述。解决城市交通通信问题,特别是特大城市日益增长的汽车交通强度,是减少城市环境风险和人为风险的主要方向之一。全球的大城市绿化概念相当重视地下空间承担最危险和最危险的地面物体和通信功能的可能性,因为任何地下物体对环境的影响都要小得多(比地面上的类似物体),并且可以更好地控制。同时,规划地下交通基础设施的发展应以系统的方法和工具为基础,以分析复杂的系统。它包括使用系统工具(BOCR方法-收益,机会,成本和风险的标准)来规划大城市的地下交通基础设施,以确保将城市空间的环境和人为风险降到最低,并优先考虑道路隧道的建设(例如,基辅市的总体规划)。提出了一种基于分层和网络标准模型计算备选方案优先级的方法和决策支持工具包。作者(N. Pankratova, N.I. Nedashkovskaya)开发的改进BOCR方法被用于评估考虑收益、成本、机会和风险的决策方案。根据基辅到2025年的总体规划,开发了两条公路隧道的系统模型。使用BOCR方法(效益、机会、成本和风险标准)对模型进行评估。根据降低城市化空间的环境风险和人为风险的标准,通过参数网络和合理的施工顺序,计算出隧道路线的优先级。科学的新奇。该系统模型首次将大城市地下基础设施发展的目标函数设定为最小化城市空间的环境风险和人为风险。改进后的BOCR方法的功能得到了扩展,并成功地测试了两种替代的隧道轨道模型。现实意义。研究方法和结果为投资者、城市国家管理部门和公共组织提供了有效的工具,用于评估地下城市设施建设的优先级,以规范城市发展,从而提高特大城市的环境标准和生活安全。

Youth migration in Ukraine: regional dimension 乌克兰青年移徙:区域层面
Purpose. This study aims to analyze the regional differentiation of youth migration flows and typify the regions of Ukraine according to the characteristics of the migratory behavior of the youth. Accordingly, the research questions are as follows: 1) what is the relationship between economic indicators (income, unemployment, investment) and youth migration at the regional level? 2) how do the regions of Ukraine differ in the scale, structure, and dynamics of youth migration flows? 3) what types of regions can be identified, and can they be considered to determine the young people’s intention to migrate? Research methods. Pearson's correlation coefficients were calculated to assess the relationship between youth migration and economic indicators at the regional level. To prevent skewed indicators distribution, the city of Kyiv was excluded from the analysis. In order to study the regional differentiation of youth migration, we used cluster analysis and constructed Kohonens self-organizing maps. Based on the analysis of spatial and temporal (from 2002 to 2019) trends, we also developed an empirical typification of the regions according to the migration behavior of young people. Main findings. The analysis of spatial differences in youth migration in urban and rural areas shows the diversity and complicated multidirectionality of migration flows. Youth migration has been found to be linked to unemployment and investment attractiveness at the regional level. The assumption that the migration of young people from rural areas is influenced not only by economic factors but also by the lack of prospects for tertiary education, jobs, and the ‘culture of migration’ has been confirmed. The analysis of the relationship between income and out-migration scale shows some signs of a inverse U-shape curve. In general, the results of the study confirmed that at the regional level, economic indicators (unemployment, investment, and income) affect youth migration in Ukraine, but their impact needs to be studied in the broader context of place-specific human capital and life-course transition. Based on the results of cluster analysis and construction of Kohonen self-organizing maps, five clusters of Ukraine’s regions by the similarity of youth migration were identified. The analysis of youth migrations in 2002-2019 allowed to identify six models of their dynamics (monotonically decreasing, abrupt dynamics with a tendency to decrease, abrupt dynamics without changes, abrupt dynamics with a tendency to increase, monotonically increasing, without changes). According to the combination of selected clusters of regions and models of youth migration dynamics, we empirically typified Ukraine’s regions into three groups that can be considered those that, to some extent, determine the young people’s intention to migrate. However, further research should be aimed at analyzing the individualization of migration behavior and liquid migration of Ukrainian youth. Scientific nov
目的。本研究旨在分析青年移民流动的区域差异,并根据青年移民行为的特点对乌克兰地区进行类型化。因此,本文的研究问题如下:1)在区域层面上,经济指标(收入、失业、投资)与青年移民之间的关系是什么?2)乌克兰各地区在青年移民流动的规模、结构和动态方面有何不同?3)可以确定哪些类型的区域,是否可以考虑这些区域来决定年轻人的迁移意向?研究方法。计算Pearson相关系数以评估青年移民与区域层面经济指标之间的关系。为了防止指标分布歪斜,基辅市被排除在分析之外。为了研究青年移民的区域分异,我们采用聚类分析方法,构建Kohonens自组织图。在分析时空(2002 - 2019年)趋势的基础上,我们还根据年轻人的迁移行为对各区域进行了实证分类。主要发现。城乡青年移民的空间差异分析显示了移民流动的多样性和复杂的多向性。已发现青年移徙与区域一级的失业和投资吸引力有关。青年人从农村地区移徙不仅受到经济因素的影响,而且还受到缺乏高等教育、就业前景和"移徙文化"的影响,这一假设已得到证实。对收入与外迁规模关系的分析显示出一些反u型曲线的迹象。总体而言,研究结果证实,在区域层面,经济指标(失业、投资和收入)影响乌克兰青年移民,但其影响需要在更广泛的地方特定人力资本和生命历程过渡背景下进行研究。基于聚类分析和构建Kohonen自组织地图的结果,确定了乌克兰青年移民相似性的五个区域聚类。通过对2002-2019年青年移民的分析,可以确定其动态的六种模型(单调减少、有减少趋势的突然动态、无变化的突然动态、有增加趋势的突然动态、单调增加、无变化)。根据选择的区域集群和青年迁移动态模型的组合,我们经验地将乌克兰的地区分为三组,这些区域可以被认为是在某种程度上决定年轻人迁移意图的群体。然而,进一步的研究应着眼于分析乌克兰青年迁移行为的个体化和流动迁移。具有科学新颖和实用价值。该研究的主要新颖之处在于其关注乌克兰青年移徙的空间维度,特别是确定与青年移徙有关的移徙流动、因素、趋势和区域问题的区域差异特征。所得结果的实际价值在于,某些类型的地区有可能成为乌克兰各地区移民政策的“指导方针”。

Development of offshore wind energy of Ukraine in the Sea of Azov: the geographical aspect 乌克兰在亚速海的海上风能开发:地理方面
Formulation of the problem. Ukraine's energy sector is import-dependent, and one of the country’s sustainable development goals until 2030 is to ensure access to affordable, reliable, sustainable and modern energy sources. The wind potential of the mainland of our country has been thoroughly studied, so the focus of our interest is water areas, which are promising for the development of offshore wind energy. Offshore wind farms in Ukraine could improve the environmental situation and considerably contribute to the decarbonization of domestic energy. That is why the study considers the opportunity of offshore wind farms installation in the Sea of Azov. Methods. The analysis of literary and cartographic sources has been carried out. Mathematical methods have been used to calculate energy indicators. Using geoinformation modeling, taking into account limiting factors, suitable for the installation of offshore wind farms areas have been identified in the Sea of Azov. The purpose of the article is to geographically analyze the wind energy potential of the Sea of Azov with further assessment of the suitability of areas for the offshore wind farms location. Results. Our research has shown that the installation of offshore wind farms is appropriate in the Sea of Azov, because many areas are characterized by average annual wind speed above 6 meters per second. The most promising areas are the northern and northeastern coasts, where wind speed at different altitudes ranges from 8 to 9.3 meters per second. At altitudes of 50, 100 and 200 m, under the action of limiting factors, the most promising for offshore wind turbines areas are reduced by 8–22%. As considered limiting factors (territorial waters, nature protection objects, settlements and airports) have identical influence regardless of height, it is more effective to install wind turbines with a tower height of more than 100 m in the waters of the Sea of Azov. Interdisciplinary research is needed for the final answer on the effectiveness of offshore wind turbines in the Sea of Azov. Scientific novelty and practical significance. The results of the analysis of the wind energy potential of the Sea of Azov have been given, the tendency of its growth from the west to the east has been revealed. Attention has been paid to the method of geoinformation modeling of the location of offshore wind farms taking into account limiting factors. Maps of wind speed, potential of electricity generated by a single wind turbine and suitability of areas of the Sea of Azov for the location of offshore wind farms at an altitude of 200 m above sea level have been presented. These data can be used by designers of wind energy facilities as a basis for determining the optimal power of wind turbines and the type of energy for a particular area of the Sea of Azov.
问题的表述。乌克兰的能源部门依赖进口,该国到2030年的可持续发展目标之一是确保获得负担得起的、可靠的、可持续的和现代的能源。我国大陆的风力潜力已经得到了深入的研究,因此我们关注的重点是有发展海上风能前景的水域。乌克兰的海上风力发电场可以改善环境状况,并大大有助于国内能源的脱碳。这就是为什么该研究考虑在亚速海安装海上风力发电场的机会。对文献资料和地图资料进行了分析。利用数学方法计算能量指标。利用地理信息建模,考虑到限制因素,确定了适合在亚速海安装海上风电场的区域。本文的目的是对亚速海的风能潜力进行地理分析,并进一步评估海上风电场选址的适宜性。我们的研究表明,在亚速海安装海上风电场是合适的,因为许多地区的年平均风速超过每秒6米。最有希望的地区是北部和东北部海岸,那里不同海拔的风速从每秒8米到9.3米不等。在50米、100米和200米的海拔高度,在限制因素的作用下,海上风力发电最有前景的区域减少了8-22%。考虑到限制因素(领海、自然保护对象、定居点和机场)无论高度如何都具有相同的影响,因此在亚速海水域安装塔高超过100米的风力涡轮机更为有效。为了最终确定亚速海海上风力涡轮机的有效性,需要进行跨学科的研究。具有科学新颖性和现实意义。本文给出了亚速海风能潜力的分析结果,揭示了亚速海由西向东发展的趋势。研究了考虑限制因素的海上风电场选址地理信息建模方法。风速、单个风力涡轮机产生的潜在电力以及亚速海地区在海拔200米以上的海上风力发电场位置的适宜性的地图已经提出。风能设施的设计者可以使用这些数据作为确定风力涡轮机的最佳功率和亚速海特定区域的能源类型的基础。

Features of dynamics of the Southern Buh river aquatic environment parameters during the summer low-water period 夏季低潮期南布河水环境参数动态特征
Formulation of the problem. Global climate change causes transformation in the humidification regime and, as a result, makes adjustments to economic activities and features of water use. In the context of Ukraine, against the background of climate change, the runoff of most domestic rivers is declining, which especially in the limited period exacerbates the issue of balanced use of ecosystem services of aquatic ecosystems and prioritization of needs during resource allocation, control of rivers and establishment of their functioning. The purpose of the article. Recognizing the strategic importance of freshwater ecosystems in ensuring sustainable regional and national development, the study of the Southern Bug River was aimed at assessing its ecological status in order to identify sources of negative anthropogenic impact and identify general ecosystem distortions that may affect the functional integrity of the aquatic ecosystem. Methods. The research points on the Southern Bug River were determined by the method of randomization. The total length of the route was about 200 km. Also, the spatial location of settlements was taken into account, so that the investigated points were both upstream and downstream. Measurement of physicochemical parameters was performed by instruments: TDS-3, TDS/ЕС/Temp-meter HM COM-100, pH-meter Ezodo 6011A. The task of hydrobiological research was to find and identify species at the family level. The research was conducted at the end of July 2020, when the river entered to low flow phase. Results. On the basis of field research, the assessment of the ecological state of the Southern Bug River in the lower course (from the city of Pivdennoukrainsk) was carried out in the work. Regularities of pH dynamics and mineralization of the aquatic environment are established. The limits of the spatial influence of the Black Sea waters on the Southern Bug, the continental advance of which (upstream) almost 100 km up is due to the high level of regulation of basin runoff, have been specified. The same processes, as a consequence, affect not only biodiversity, but also the features of industrial and domestic water use. Using the stenobiontic approach, the level of ecological safety of the Southern Bug ecosystem in the lower course was assessed. Based on the obtained results of stenobioindication, the zoning of the studied area of the Southern Bug is proposed, which compares quite well with the results of pH and mineralization measurements. Only 1% of the route, which corresponds to the porous section of the river channel, was classified as a "healthy ecosystem". The closer to the mouth, the pH of the water gradually increases, which contributes to the intensification of the eutrophication process. Scientific novelty and practical significance. The obtained results are considered to be an integral part of future field research on the identification of sources of negative impact on the aquatic ecosystem of the Southern Bug. The n
问题的表述。全球气候变化导致了加湿制度的转变,并因此对经济活动和用水特征进行了调整。以乌克兰为背景,在气候变化的背景下,大多数国内河流的径流量正在下降,特别是在有限的时期内,这加剧了平衡利用水生生态系统生态系统服务和在资源分配、河流控制和建立其功能过程中优先考虑需求的问题。文章的目的。认识到淡水生态系统在确保区域和国家可持续发展中的战略重要性,对南布格河的研究旨在评估其生态状况,以确定负面人为影响的来源,并确定可能影响水生生态系统功能完整性的一般生态系统扭曲。采用随机化方法确定南布格河的研究点。路线的总长度约为200公里。同时考虑了聚落的空间位置,使调查点在上游和下游都有。理化参数测量仪器:TDS-3、TDS/ЕС/ temp - HM COM-100、pH-meter Ezodo 6011A。水生生物学研究的任务是在科的水平上发现和鉴定物种。该研究于2020年7月底进行,当时河流进入低流量阶段。在实地调查的基础上,对南布格河下游(从皮维登努克兰斯克市开始)的生态状况进行了评估。建立了水环境的pH动态和矿化规律。已经明确指出了黑海水域对南部臭虫的空间影响的极限,南部臭虫的大陆推进(上游)几乎向上100公里是由于盆地径流的高度调节。因此,同样的过程不仅影响生物多样性,而且也影响工业和家庭用水的特点。采用窄仿生方法,对河段下游南蝽生态系统的生态安全水平进行了评价。根据所获得的生物指示结果,提出了南虫研究区的分区,并与pH和矿化测量结果进行了比较。只有1%的路线,对应于河道的多孔部分,被归类为“健康生态系统”。越靠近河口,水的pH值逐渐升高,这有助于富营养化过程的加剧。具有科学新颖性和现实意义。所获得的结果被认为是未来对南蝽水生生态系统负面影响来源识别的实地研究的一个组成部分。所得结果的新颖之处在于对河流生态系统在低流量期的生态状态进行了综合评估,与最大允许浓度的概念相反,它表征了南虫点的状态,但考虑了人为影响的累积效应和协同效应。后者在夏季表现最好,因此河流食物链的结构和生物量发生了显著变化。此外,对河流水资源合理利用的分析表明,现代环境标准体系,特别是规范水环境质量的标准体系,并不能保证河流生态系统的保护。

The rivers in Kharkiv urban space: the history of interaction between nature and society (second half of the XVIIth - early XXIth century) 哈尔科夫城市空间中的河流:自然与社会互动的历史(18世纪下半叶- 21世纪初)
Formulation of the problem. This article is devoted to the critical topic of modern Urban studies –the river’s role in urban space. There are many projects of the river’s revitalization in the USA, South Korea, and Europe. These projects improve the condition of climate and ecology in cities and renew rivers have become attractive places for citizens and tourists. In Ukraine, such projects are not so popular, but during the last years, in several cities NGOs, which try to attract attention to this topic, have appeared. Nevertheless, the revitalization project must begin from the deep investigation into the history and natural condition of the river. Therefore, this article’s object is the interaction between the Rivers and the Society in the Kharkiv urban space during the second half of 17th – the early 21st century. The topic was divided to five periods. The first was the second half of 17 – the middle of 18, when the city was the fortress on The Wild Field’s border.

问题的表述。本文致力于现代城市研究的关键话题——河流在城市空间中的作用。在美国、韩国和欧洲,有许多振兴这条河的项目。这些项目改善了城市的气候和生态条件,更新了河流,成为吸引市民和游客的地方。在乌克兰,这样的项目不太受欢迎,但在过去几年中,在几个城市出现了非政府组织,试图引起人们对这一主题的关注。然而,振兴工程必须从深入调查河流的历史和自然条件开始。因此,本文的研究对象是17世纪下半叶至21世纪初哈尔科夫城市空间中河流与社会的互动。这个题目分为五个阶段。第一次是17年下半年,18年中期,当时这座城市是荒野边境的堡垒。接下来是1764 - 1860年,哈尔科夫是俄罗斯帝国典型的行政中心。1860 - 1917年,城市的迅猛发展极大地加剧了人为对城市空间的压力。第四次是1917年至1991年,当时该市处于苏联城市政策之下。最后——近代乌克兰独立时期,当振兴项目成为现实。回顾以前的出版物和研究。哈尔科夫蓝色空间的状况是19 - 21世纪历史学家、生态学家、建筑师和政界的重要主题。由于工业对河流的影响导致生态问题,19世纪的欧洲开始讨论城市空间中河流的全球主题。在过去的十年里,马丁吸引了人们对普罗维登斯河(美国)的历史和复兴的关注。S. Castonguay, M. Evenden发表了关于河流在城市空间中的深刻研究。Jaime Lerner在他的研究«acuuntura Urbana»中确定了河流的位置,乌克兰生态学家继续研究乌迪,哈尔科夫和洛潘的污染水平。使用原始的城市研究方法,我们将河流视为对称城市网络的一部分。这意味着河流是城市联系的积极参与者,可以影响网络的其他要素。在我们主题的五个阶段中,河流在城市空间中扮演了以下角色:污水、分区、经济、娱乐和审美。这些功能的意义和规模随着历史时期的变化而变化。不受管制地使用水源会导致河流污染、传染病传播和洪水。具有科学新颖性和现实意义。复兴的过程始于对哈尔科夫城市空间中河流位置的深刻跨学科研究。在本文中,我们确定了问题的分期,河流的主要功能,以及它们在这一时期的作用变化。下一步必须是将河流作为基于其历史的文化对象进行复兴的项目。

This article is devoted to the critical topic of modern Urban studies –the river’s role in urban space. There are many projects of the river’s revitalization in the USA, South Korea, and Europe. These projects improve the condition of climate and ecology in cities and renew rivers have become attractive places for citizens and tourists. In Ukraine, such projects are not so popular, but during the last years, in several cities NGOs, which try to attract attention to this topic, have appeared. Nevertheless, the revitalization project must begin from the deep investigation into the history and natural condition of the river. Therefore, this article’s object is the interaction between the Rivers and the Society in the Kharkiv urban space during the second half of 17th – the early 21st century. The topic was divided to five periods. The first was the second half of 17 – the middle of 18, when the city was the fortress on The Wild Field’s border.

On the question of geological prerequisites of Dnieper-Donets depression hydrodynamic traps formation 论第聂伯-顿涅茨凹陷水动力圈闭形成的地质条件问题
Formulation of the problem. Hydrocarbon pools in hydrodynamic traps are known within many oil and gas provinces. The Dnieper-Donets basin is one of the regions where non-vault traps of almost all types and associated with them hydrocarbon pools are widespread, while HT in DDD are not yet typical, although the geological structure of the region indicates the possibility of their formation. Thus, substantiation of the role of geological preconditions in the processes of hydrodynamic type traps formation is the main task of the work. Analysis of recent research and publications. In the monograph of O. Plotnikov (2001) among the promising regions for the search for HT defined DDD. The reason for this was the data on the presence in some productive horizons, in particular in the Sorochinsky and Rudenkivsky fields, of formation waters that lie above gas-bearing deposits. It is believed by some researchers, that the leading role in the formation of gas accumulations at these fields belongs to formation waters. According to the results of geological and geophysical study of the southern slope of the Kalmius-Torets depression and the Krasnoarmijska monocline in the south-eastern part of the DDD (A. Terdovidov (2000), S. Pavlov (2004), favorable geological prerequisites for the formation of HT in Paleozoic sediments established. Selection of previously unsolved parts of the overall problem. The general problem of searching for HT in the DDD as a whole task has not been solved so far. Formulation of the purpose of the article. Estimation of possibilities of a new direction of search and reconnaissance works in DDD, namely on non-traditional non-vault traps of hydrodynamic type substantiation. Results. The Visean dominant productive complex, regionally extended on the monocline slopes of the northern and southern sides of the depression and lithologically represented mainly by sandy horizons, was selected for priority research. The significant content of alluvial sandstones in Visean sediments section allowed the authors to consider them as special reservoirs of fluids, and paleoalluvial systems to study in the rank of independent search objects. Their territorial location is logically related to the existing deflections of the surface of the crystalline basement, most of which are associated with modern river systems, which indicates the current functioning of their relationship. The authors made an attempt to substantiate within the northern side of the DDD the following forecast water exchange systems: 1) expultional overflowing; 2) docking regime (both in the terminology of O. Plotnikov) in Paleozoic sediments; 3) infiltration water exchange in Mesozoic sediments, as necessary conditions for catching migrating upward hydrocarbons. The decrease in the infiltration waters velocity to insignificant values is interpreted by the authors as a typical phenomenon for "closed" monoclines, within which there was an equilibrium between the pressure of infiltra
问题的表述。水动力圈闭中的油气藏在许多油气省都是已知的。第聂伯-顿涅茨盆地是几乎所有类型的非拱顶圈闭及其伴生油气藏普遍存在的地区之一,而DDD的高温圈闭尚不典型,尽管该地区的地质构造表明了其形成的可能性。因此,证实地质条件在水动力型圈闭形成过程中的作用是本工作的主要任务。分析最近的研究和出版物。在O. Plotnikov(2001)的专著中,在寻找HT的有希望的区域中定义了DDD。其原因是在一些生产层位,特别是在Sorochinsky和Rudenkivsky油田,位于含气矿床上方的地层水的存在数据。一些研究人员认为,在这些气田的天然气聚集形成中起主导作用的是地层水。A. Terdovidov (2000), S. Pavlov(2004)对DDD东南部Kalmius-Torets凹陷南坡和Krasnoarmijska单斜的地质和地球物理研究结果,为古生代沉积物中高温沉积的形成奠定了良好的地质条件。选择整体问题中以前未解决的部分。在整个DDD任务中搜索HT的一般问题到目前为止还没有得到解决。文章目的的表述。在DDD中搜索和侦察工作新方向的可能性估计,即水动力型物质的非传统非拱顶圈闭。研究重点选择了在凹陷南北两侧单斜斜坡上区域伸展、岩性以砂质层为主要代表的Visean优势生产杂岩。Visean沉积物剖面中冲积砂岩的显著含量使作者可以将其视为特殊的流体储层,并将古冲积体系作为独立的搜索对象进行研究。它们的领土位置在逻辑上与晶体基底表面的现有偏转有关,其中大多数与现代河流系统有关,这表明它们之间的关系目前正在发挥作用。作者试图证实在干旱区北侧预测的水交换系统:1)排出式溢出;2)古生代沉积物的对接机制(都是O. Plotnikov的术语);3)中生代沉积物的入渗水交换,是捕获向上运移的油气的必要条件。入渗水流速降低到不显著值,作者认为这是“封闭”单线的典型现象,在这一现象中,入渗水压力与排出流体阻力之间达到了平衡。这种平衡被看作是为水动力捕获创造条件的术语。结论强调需要进行全面的研究,以确认水交换的预测模型,并获得绘制可能存在碳氢化合物聚集的最小压力测量值的数据。
