The black shale complex, which is organic carbon-bearing and characterized by syngenetic, epigenetic sulphidation and intense metamorphism in the Duruja structural-forma- tion zone of the southern slope of the Greater Caucasus, is the focus of geologists’ attention due to the mineralization areas, which are rich in significant non-ferrous, noble, radioactive metals, rare and rare earth elements. In order to determine the prospects of noble, non-ferrous, radioactive metals, rare and rare earth elements of the black shale of the Aghlig-Filfilli mineralization area of the Duruja zone, it is necessary to determine the mineralogical composition of the ores of the area, to study the textural-structural characteristics and to clarify whether the rocks of the zone are a source of complex ore raw materials. The object of the work is the mineragraphic and petrographic study of the numerous samples col- lected from the Aghlig-Filfilli mineralization area during the field expedition before the PhD admission period, during my post-graduate studies and currently in order to solve various important mineralogical and petrographic problems. In order to investigate the textural-structural characteristics and mineral types of the ores of the Aghlig-Filfilli mineralization area, thin sections and polished sections made from the samples were studied with the help of «Carl Zeiss» and «Polam-312» microscopes in transmitted and reflected rays. The composition, surface area and morphological characteristics of the monomineral samples were studied by the electron microscope «SEM». Accurate diagnosis of some minerals was carried out based on the results of their X-ray diffractometric analysis. According to the results of the research, the ores of the Aghlig-Filfilli mineralization area were formed in 3 stages: syngenetic, epigenetic and rem- ineralization as a result of strong metamorphism of syngenetic formations. At the same time, the origin of the ores of the Aghlıg-Filfilli mineralization area was studied. According to the results of the research, it was determined that epigenetic mineralization in contact with Aralig and Zangi deep faults in the north and south of the Aghlig-Filfilli area is of magmatogene origin (δ34S=1.6-4.6), and synge- netic mineralization in the black shales towards the center is of biogenic origin (δ34S= -18 – -22.6).
大高加索南坡杜鲁加构造-造山带黑色页岩杂岩是一个有机含碳、同生、表生硫化作用和强烈变质作用的黑色页岩杂岩,其成矿区富含重要的有色金属、贵金属、放射性金属和稀有稀土元素,是地质学家关注的焦点。为了确定杜鲁加带aghligi - filfilli矿化区黑色页岩中贵金属、有色金属、放射性金属、稀土元素和稀土元素的远景,需要确定该区矿石的矿物组成,研究其结构构造特征,明确该区岩石是否为复杂矿石原料的来源。这项工作的目的是对博士入学前、研究生学习期间和目前在aghligi - filfilli矿化区实地考察期间收集的大量样品进行矿物学和岩石学研究,以解决各种重要的矿物学和岩石学问题。为了研究aghligi - filfilli矿化区矿石的结构特征和矿物类型,在“卡尔蔡司”和“Polam-312”显微镜的透射和反射光线下,对样品的薄片和抛光切片进行了研究。利用电子显微镜(SEM)研究了样品的组成、表面积和形貌特征。根据x射线衍射分析的结果,对某些矿物进行了准确的诊断。研究结果表明,aghligi - filfilli矿化区矿石在同生地层强烈变质作用下,形成了同生、表生和再成矿3个阶段。同时,对Aghlıg-Filfilli矿化区矿石的成因进行了研究。根据研究结果,确定aghligi - filfilli地区南北与Aralig和Zangi深断裂接触的表生成矿作用为岩浆成因(δ34S=1.6 ~ 4.6),靠近中部的黑色页岩同磁成矿作用为生物成因(δ34S= -18 ~ -22.6)。

The article reveals the mutual influences of the geography of small towns (mistechka) and rural settlements in Ukraine and the system of administrative-territorial organization at the middle and lowest levels. Based on the statistical analysis, it was concluded that the location of very small cities, urban-type settlements (selyshchа miskoho typu) and villages is significantly differentiated by regions of Ukraine, taking into account the historical-geographical and natural-geographical prerequisites, the level of urbanization and industrialization, as well as differences in the demographic situation. The study proved that before the administrative reform, the small towns of Ukraine played an important role in the organization of the middle link of the administrative territorial system, being the centers of most districts, but as a result of the reform, their administrative importance in the district division became minimal. At the same time, almost half of the small towns became centres of united territorial communities. The author concludes that the loss of the status of medium-sized administrative units by towns could be compensated by transferring a significant part of the functions of regional authorities to new administrative districts, and most of the functions of former district centres to the centres of low-level territorial communities. For this purpose, it is necessary to create appropriate socio-economic conditions for the small towns-centres of new territorial communities to perform all the functions of serving the population of nearby settlements. It was concluded that such changes in administrative powers can ensure, in general, a shift in the weight of socio-economic life deep into the territory, which is necessary to overcome intra-regional disproportions in the development of the economy and the social sphere. The proposition that the structure of rural resettlement also influenced the territorial organization of local self-government in rural areas in different ways at all times was conceptually substantiated. The main socio-geographic parameters that used to determine and currently determine the structure of rural self-government are the density of the rural population, the average population, and the density of rural settlements. The study proved the presence of various regional variants of the combination of these indicators, which were also reflected in the geography of the centres in rural territorial communities. A positive consequence of the administrative reform was the strengthening of the financial base of rural communities, but at the same time, the administrative importance of many rural settlements of Ukraine decreased due to the loss of the status of rural council centres, and the distances between rural settlements and new administrative centres increased. As villages-community centres began to serve larger territories, if their infrastructural potential and economic base were strengthened, they could become
本文揭示了乌克兰小城镇(米什奇卡)和农村居民点的地理与中下层行政-领土组织制度的相互影响。根据统计分析,得出的结论是,考虑到历史地理和自然地理先决条件、城市化和工业化水平以及人口状况的差异,乌克兰各地区的非常小的城市、城市型住区(selyshchva miskoho typu)和村庄的位置差别很大。研究证明,在行政改革之前,乌克兰的小城镇在行政领土体系的中间环节的组织中发挥了重要作用,是大多数地区的中心,但改革后,它们在地区划分中的行政重要性变得微不足道。与此同时,几乎一半的小城镇成为联合领土社区的中心。作者的结论是,城镇丧失中型行政单位的地位可以通过将地区当局的大部分职能转移到新的行政区域,并将以前的地区中心的大部分职能转移到低级领土社区的中心来弥补。为此目的,有必要为新的领土社区的小城镇中心创造适当的社会经济条件,以履行为附近住区人口服务的所有职能。会议的结论是,行政权力的这种变化一般可以确保将社会经济生活的重心转移到领土深处,这是克服经济和社会领域发展的区域内不平衡所必需的。农村安置结构在任何时期都以不同的方式影响着农村地方自治的地域组织,这一命题在概念上得到了证实。过去和现在决定农村自治结构的主要社会地理参数是农村人口密度、平均人口密度和农村居民点密度。这项研究证明,这些指标的组合存在不同的区域差异,这也反映在农村领土社区中心的地理位置上。行政改革的一个积极后果是加强了农村社区的财政基础,但与此同时,由于农村委员会中心的地位丧失,乌克兰许多农村住区的行政重要性下降,农村住区与新的行政中心之间的距离增加。随着村-社区中心开始为更大的领土服务,如果它们的基础设施潜力和经济基础得到加强,它们可以成为农村地区社会经济发展的新极。

This study was conducted within the Zambezi River Basin to ascertain the bathymetry and sedimentation of selected reservoirs, evaluate their seasonal hydrological regimes, pinpoint the causes of reservoir siltation, and determine how the bathymetry and siltation impacted water-related industries and policy choices. Hydrological field measurements using a hydrographic survey boat, document studies, and interviews were used to collect the data. The 3D spatial analyst tools in ArcGIS 10.3 and hypsometric curves were used to analyze bathymetric data. Thematic analysis was used to analyze qualitative interview data. Findings indicated that sedimentation was a problematic phenomenon spatial-temporally and, it triggered a significant decrease in the storage capacities of the reservoirs. The study noted that catchments with small reservoirs were vulnerable to severe water stress, particularly from July through the beginning of the next rainy season in December. Over 90% of the local population and water-related industries were facing substantial risks of economic water shortages and may continue to face more water challenges amidst escalating climatic changes. The problem could be addressed by coping mechanisms such as alternative livelihoods, water harvesting, and water shedding. This study proposes an Integrated Water Resources Management Framework, which may help incorporate water education to bring about behavioural change against drivers of sedimentation. The proposed sediment and water resources management model serves as a multidisciplinary and transdisciplinary tool that could be used to address siltation concerns. This work has also shown the significance of bathymetric surveys of small reservoirs as a basis for policy context and regulations on managing water resources.
本研究在赞比西河流域内进行,以确定选定水库的水深和沉积情况,评估其季节性水文状况,查明水库淤积的原因,并确定水深和淤积如何影响与水有关的工业和政策选择。利用水文测量船进行水文实地测量、文献研究和访谈来收集数据。利用ArcGIS 10.3中的三维空间分析工具和等深曲线对水深数据进行分析。采用专题分析对定性访谈数据进行分析。研究结果表明,泥沙淤积是一种时空上的问题现象,它会导致水库蓄水能力的显著下降。该研究指出,小型水库的集水区容易受到严重的水资源压力,特别是从7月到12月下一个雨季开始。超过90%的当地人口和与水相关的行业面临着经济缺水的重大风险,并可能在气候变化加剧的情况下继续面临更多的水挑战。这个问题可以通过诸如替代生计、集水和排水等应对机制来解决。这项研究提出了一个水资源综合管理框架,这可能有助于将水教育纳入其中,以改变人们的行为,防止沉积的驱动因素。拟议的沉积物和水资源管理模型是一种多学科和跨学科的工具,可用于解决淤积问题。这项工作也显示了小型水库的水深测量作为管理水资源的政策背景和规章的基础的重要性。

Cascadia Earthquake-Triggered Rockslide Burial of Beeswax Galleon Wreck Timbers in a Sea Cliff Wave-Cut Platform Site, North Smuggler Cove, Oregon, USA 美国俄勒冈州北走私者湾海崖波浪切割平台遗址,卡斯卡迪亚地震引发的蜂蜡帆船残骸木材的岩石滑坡埋葬

Shipwreck timbers (n=27) from the Spanish galleon Santo Cristo de Burgos, also known as the Beeswax Wreck (lost in 1693), are examined for origins of multiple, simultaneous rockslide burials that protected and preserved the timbers on an intertidal wave-cut platform in the small Smuggler Cove in the Northern Oregon coast. The rockslides (n=3–4) that buried the shipwreck timbers are compared to nearby historic rockslide analogs to better establish the mechanisms of boulder distributions on the wave-cut platform. Large boulders (n=20), generally ≥1.0 m intermediate diameter, in the North Smuggler Cove (NSC) timber burial site were measured for estimated mass (1–41 t) and alongshore distribution below small gullies that routed the boulders to the wave-cut platform from overlying short (~100 m distance) but steep hillslopes (40–60% gradient). The multiple independent rockslides in the NSC site, dated to ~300 years by the buried Beeswax Wreck timbers, showed catastrophic, simultaneous activation by a widespread trigger. Anomalous rainfall and/or storm wave attack are unlikely mechanisms for these rockslide activations due to 1) hillslope protections from extended-upslope surface water discharge and 2) sea cliff protection from direct storm wave impacts. The most likely widespread trigger for rockslide activation in the NSC site is seismic ground shaking from an earthquake in the Central Cascadia subduction zone. Modern storm wind velocities (>10 s-1 sustained velocity and 170–225° bearing) and storm surge generated rip currents (≥0.5 km offshore distance) indicate that Beeswax Wreck timbers could have been transported north (1–10 km) to Smuggler Cove, within several winter seasons after the breakup of the Santo Cristo de Burgos. The most likely seismic trigger that could have activated the multiple rockslides in the NSC site, shortly after the brief accumulation of shipwreck timbers on the narrow, intertidal wave-cut platform in Smuggler Cove, is the 1700 Cascadia great earthquake (Mw~9.0). Additional sea cliff rockslide sites (n=8) in the central Cascadia margin are suggested for further investigations of seismically activated slope failures by the 1700 Cascadia great earthquake.
西班牙大帆船圣克里斯多·德·布尔戈斯的沉船木材(n=27),也被称为蜂蜡残骸(1693年丢失),在俄勒冈州北部海岸的小走私者湾的潮汐间波浪切割平台上,研究了多个同时发生的岩石滑坡埋葬的起源,这些埋葬保护和保存了木材。将掩埋沉船木材的岩石滑坡(n= 3-4)与附近历史上类似的岩石滑坡进行比较,以更好地建立波浪切割平台上巨石分布的机制。在北走私者湾(NSC)木材掩埋地点,测量了大石块(n=20),通常中间直径≥1.0 m,估计质量(1-41 t)和沿海岸分布在小沟壑下,这些沟壑将巨石从上覆的短(~100 m距离)但陡峭的山坡(40-60%坡度)引导到波浪切割平台。在国家安全委员会遗址的多个独立的岩石滑坡,通过埋藏的蜂蜡残骸的木材可以追溯到300年前,显示出由一个广泛的触发因素同时发生的灾难性的激活。异常降雨和/或风暴波攻击不太可能是这些岩崩激活的机制,因为1)山坡保护免受延伸的上坡地表水排放的影响,2)海崖保护免受风暴波的直接影响。在国家安全委员会地区引发岩石滑坡的最可能的广泛触发因素是中部卡斯卡迪亚俯冲带的地震引起的地面震动。现代风暴风速(>10 s-1持续速度和170-225°方位)和风暴潮产生的离岸流(离岸距离≥0.5公里)表明,在Santo Cristo de Burgos解体后的几个冬季,蜂蜡残骸的木材可能被向北(1-10公里)运送到Smuggler Cove。1700年卡斯卡迪亚大地震(Mw~9.0)是在走私者湾狭窄的潮间带波浪切割平台上短暂堆积沉船木材后不久,最有可能引发NSC现场多重岩石滑坡的地震触发器。建议在中部卡斯卡迪亚边缘的其他海崖岩崩地点(n=8)进一步研究1700年卡斯卡迪亚大地震引起的地震诱发的边坡破坏。

Tectogenesis as a factor influencing the stability of rock masses of the Northern iron ore district of the Kryvbas 构造作用是影响克里夫巴斯北部铁矿区岩体稳定性的一个因素
IF 0.5 Q4 GEOSCIENCES, MULTIDISCIPLINARY Pub Date : 2023-01-12 DOI: 10.15421/112274

In the Northern iron-ore district of the Kryvbas basin, mining of deposits of poor magnetic ores is underway in two quarries – Pervomaiskyi and Hannivsky. Oftentimes, their mine contours contain low-valuable or unusable magnetite-silicaceous quarzites of containing ferrous and slate horizons. As a result, excavated ore mass contains ores and partly containing rocks of various mineral and chemical compositions and physical and technical properties. This caused diversity (15 mineral kinds) of the compositions of ores mined from the both deposits. Variability of mineral compositions of ores and rocks is due to manifesta- tions of numerous geological processes such as sedimentation, metamorphism, tectogenesis, metasomatism, supergene, etc. Various mineralogical, geochemical courses of the processes resulted in variability in physical, technical characteristics of ores and containing rocks, and this, in turn, caused various stability of rock masses during drilling-explosive works and mining. Stability of pit walls of the quarries of iron-ore deposits of the Kryvyi Rih basin is a sharp issue for mining enterprises. Solutions to those issues have been analyzed in various aspects. A number of factors take effects on the indicator of stability of rock masses within deposits, particularly mineralogical, geochemical, tectonic, etc. This paper looks at the influence of the tectonic factor specifically, which actively manifests within the Pervomayskyi and Hannivskyi deposits as fractures, breccias, mylonite of ores and rocks. During the surveys, there were designated tectonically altered kinds of ores and rocks within the both deposits, which take effects on seismic stability of pit walls of the both quarries, and also we put areas with various tectonic intensities on schematic maps. For this purpose, we used geological methods of study (selection of samples, mapping), mineralogical (determining quantitative proportions of minerals, texture, structure of ores and rocks). The study provides the data of mineralogical estimates of tectonically altered types of ores and rocks of productive layers of the Pervomaiskyi and Hannivskyi deposits of the Kryvyi Rih basin. We charted maps with areas of various manifestations of tectonic changes within productive layers of the both deposits.
在克里夫巴斯盆地的北部铁矿区,Pervomaiskyi和Hannivsky两个采石场正在开采低磁性矿石矿床。通常,他们的矿山轮廓含有低价值或不可用的含铁和板岩层的磁性硅质石英岩。因此,挖掘出的矿体含有矿石,部分含有各种矿物和化学成分以及物理和技术性质的岩石。这导致了两个矿床开采的矿石组成的多样性(15种矿物)。矿石和岩石矿物组成的变化是由于许多地质作用的表现,如沉积、变质、构造、交代、表生等。不同的矿物学和地球化学过程导致矿石和含矿岩石的物理、技术特性的变化,进而导致钻爆工程和采矿过程中岩体的各种稳定性。克里维依盆地铁矿采石场的矿壁稳定性是矿山企业面临的一个尖锐问题。对这些问题的解决方案进行了多方面的分析。影响矿床内岩体稳定性指标的因素有很多,特别是矿物学、地球化学、构造等因素。本文着重探讨了构造因素的影响,构造因素在Pervomayskyi和Hannivskyi矿床中积极地表现为裂缝、角砾岩、糜棱岩等矿石和岩石。在调查过程中,两个矿床内都有指定的构造蚀变的矿石和岩石种类,这对两个采石场的坑壁的地震稳定性产生了影响,并在示意图上标注了不同构造烈度的区域。为此,我们使用了地质研究方法(选择样品、绘制地图)、矿物学方法(确定矿物的定量比例、矿石和岩石的质地、结构)。研究提供了Kryvyi Rih盆地Pervomaiskyi和Hannivskyi矿床生产层构造蚀变的矿石和岩石类型的矿物学估计数据。我们在这两个矿床的生产层内绘制了不同构造变化表现的区域图。

Oftentimes, their mine contours contain low-valuable or unusable magnetite-silicaceous quarzites of containing ferrous and slate horizons. As a result, excavated ore mass contains ores and partly containing rocks of various mineral and chemical compositions and physical and technical properties. This caused diversity (15 mineral kinds) of the compositions of ores mined from the both deposits. Variability of mineral compositions of ores and rocks is due to manifesta- tions of numerous geological processes such as sedimentation, metamorphism, tectogenesis, metasomatism, supergene, etc. Various mineralogical, geochemical courses of the processes resulted in variability in physical, technical characteristics of ores and containing rocks, and this, in turn, caused various stability of rock masses during drilling-explosive works and mining. Stability of pit walls of the quarries of iron-ore deposits of the Kryvyi Rih basin is a sharp issue for mining enterprises. Solutions to those issues have been analyzed in various aspects. A number of factors take effects on the indicator of stability of rock masses within deposits, particularly mineralogical, geochemical, tectonic, etc. This paper looks at the influence of the tectonic factor specifically, which actively manifests within the Pervomayskyi and Hannivskyi deposits as fractures, breccias, mylonite of ores and rocks. During the surveys, there were designated tectonically altered kinds of ores and rocks within the both deposits, which take effects on seismic stability of pit walls of the both quarries, and also we put areas with various tectonic intensities on schematic maps. For this purpose, we used geological methods of study (selection of samples, mapping), mineralogical (determining quantitative proportions of minerals, texture, structure of ores and rocks). The study provides the data of mineralogical estimates of tectonically altered types of ores and rocks of productive layers of the Pervomaiskyi and Hannivskyi deposits of the Kryvyi Rih basin.

The article clarifies the peculiarities of the development of vegetation that is formed on the rock dumps of the Southern Mining and Processing Plant or their rock components (lithoecotopes), that is, only lithophilic vegetation. The problem of researching lithophilic plant communities from the point of view of forecasting their natural development and optimization is relevant not only for Kryvbas, but also for all industrial areas of open mining, in which significant masses of hard overburden rocks are brought to the surface of the earth. We have defined various lithoecotopes and described plant groups of varying complexity on plateau peaks, terraces and slopes depending on the specifics of their constituent rocks and typological features. Plant lithophilic groups of dumps of the Southern Mining and Processing Plant in accordance with the state of lithoecotopes, including all typological characteristics and geochemical nature of rocks, are marked by significant analytical (floristic and ecomorphic composition, occur- rence, stratification, physiognomy, abundance, coverage) and synthetic (similarity, constancy) differences signs A detailed study of thecondition of plants and their groups in lithoecotopes made it possible to make sure that their distribution and development have clearly defined substrate and relief-exposure dependencies, which can be used in phytotic and phytocenotic improvement of these man-made ecotopes. The natural overgrowth of all dumps has a mixed shrub-tree forest and grassy character in accordance with the typological characteristics and composition of the rocks. It was found that the change of plant communities on the lithoecotopes left without hu- man influence is endoexogenous in nature, because the ecesis external pressure is imposed on intracenotic processes. As a result of such integration, both fluctuations and successions naturally occur against the background of one or another substrate. The occurrence of species, the species and petrophytic capacity of plant communities, and their petrophytic indices in the lithoecotopes of the dumps have discrepancies depending on the specifics of the conditions. In general, the taxonomic composition of the plant communities of the dumps of the Pidennoy GZK of Kryvbas is determined by 218 species belonging to 54 families, 84 species of which are petrophytes.
本文阐明了南矿选矿厂矸石堆上或其岩石组分(岩生态组)上形成的植被发育的特殊性,即仅为亲石植被。从预测其自然发育和优化的角度研究亲石植物群落的问题不仅与Kryvbas有关,而且与所有露天开采工业区有关,其中大量坚硬的覆盖岩层被带到地球表面。我们已经定义了各种岩石生态组,并根据其组成岩石和类型特征描述了高原山峰、梯田和斜坡上不同复杂性的植物群。根据岩石生态状态,包括岩石的所有类型特征和地球化学性质,南方矿业加工厂垃圾场的植物亲石群具有重要的分析(植物区系和生态组成、产状、分层、地貌、丰度、覆盖)和综合(相似性、通过对岩石区植物及其类群状况的详细研究,可以确定它们的分布和发育具有明确的底物依赖性和地形暴露依赖性,这可用于这些人工生态区的植物性和植物生态性改良。根据岩石的类型特征和组成,所有垃圾场的自然植被都具有灌木、乔木和草的混合特征。研究发现,在没有人为影响的情况下,岩石区植物群落的变化在本质上是内源性的,因为外部压力施加于内源性过程。作为这种整合的结果,波动和演替自然都是在一个或另一个基底的背景下发生的。垃圾场岩石区的物种发生、植物群落的种类和岩石生长能力及其岩石生长指数因条件的不同而存在差异。总体而言,Kryvbas松林堆区植物群落的分类组成由54科218种组成,其中岩石植物84种。

For a long time, the tourism industry was considered one of the economy’s lead- ing and most progressive sectors, characterized by an advanced scale of development. The situation was changed fundamentally by the COVID-19 pandemic, which caused significant losses at the global level, not only for tourism but also for all sectors of the economy and society. In this regard, the provision of this article identifies the nature of the impact of the COVID-19 pandemic on tourism in a particular country in the European region using cluster analysis. In the first stage of this work, a detailed literature review on the existence of such a connection was carried out with the help of bibliometric analysis. The authors used the results published in Scopus and Web of Science databases for the keywords «tourism», and «Covid-19» and analyzed the growth dynamics in their number and citations, belonging to the research area and the spread of geography. Building a bibliometric map of keywords based on their joint placement in the VOSviewer software complex deepened findings. It made it possible to form 10 clusters, each of which covers scientific works on various forms of the impact of the COVID-19 pandemic on tourism (for example, behavioral, marketing, economic, environmental, psychological aspects, etc.). In the second stage, an analytical review was conducted, which showed a significant drop in the absolute and apparent contribution of travel and tourism to GDP worldwide in 2020 and 2021 worsened with the pandemic level, and an increase in the dynamics of key indicators of the tourism industry in the world and across all UNWTO regions (especially Asia & Pacific). In the last step, a hierarchical agglomerative cluster analysis (with Ward’s method) was carried out for the countries of the European region (45 countries) based on indicators of the number of COVID-19 cases in the country (cumulative and new), vaccination of the population, the presence of restrictions on tourism, international tourist arrivals, and receipts, collection of tourism in exports. All indicators for analyzing the collected state are provided as of July 30, 2022, using the Stata SE 12 software complex. The construction of a dendrogram and the use of Calins- ki-Harabasz and Duda-Hart stopping rules made it possible to decide on the presence of 3 clusters that meet the conditions of this study and are characterized by different levels of adaptability to post-pandemic functioning and recovery direction.
长期以来,旅游业被认为是经济的主导和最先进的部门之一,具有先进的发展规模。2019冠状病毒病大流行从根本上改变了这一局面,不仅在全球范围内对旅游业造成了重大损失,而且对经济和社会的所有部门造成了重大损失。在这方面,本文的规定使用聚类分析确定了COVID-19大流行对欧洲地区特定国家旅游业影响的性质。在本工作的第一阶段,借助文献计量学分析对这种联系的存在进行了详细的文献综述。作者利用Scopus和Web of Science数据库中发表的关键词“旅游”和“Covid-19”的结果,分析了它们在研究领域的数量和引用的增长动态,以及地理传播。根据关键词在VOSviewer软件综合体中的联合位置,构建了一个关键词的文献计量图,加深了研究结果。这使得形成10个集群成为可能,每个集群涵盖有关COVID-19大流行对旅游业的各种形式影响的科学著作(例如,行为、营销、经济、环境、心理等方面)。在第二阶段,进行了一项分析审查,结果显示,2020年和2021年全球旅行和旅游业对国内生产总值的绝对和表观贡献大幅下降,随着大流行的程度而恶化,世界和世界旅游组织所有区域(特别是亚太地区)旅游业关键指标的动态有所增加。最后一步,根据欧洲地区国家(45个国家)的COVID-19病例数(累积和新发病例)、人口疫苗接种、旅游限制的存在、国际游客入境人数和出口旅游收入等指标,对欧洲地区国家(45个国家)进行了分层聚集聚类分析(使用Ward方法)。所有用于分析收集状态的指标都是截至2022年7月30日,使用Stata SE 12软件综合体提供的。树形图的构建和Calins- ki-Harabasz和Duda-Hart停止规则的使用使得有可能确定满足本研究条件的3个集群的存在,并且具有对大流行后功能和恢复方向的不同程度的适应性。

In the world, the living conditions and health of the population have a certain impact on demographic processes. High population growth rates cause demographic problems. As a positive solution to these problems, a number of international organizations, including the United Nations Population Fund, have set the main task of «improving the lifestyle of the population and ensuring sustainable development» (https://www.unfpa.org/world-population-trends). These tasks include studies aimed at identifying and evaluating the features of the development of demographic processes in densely populated areas, the factors influencing them, and developing a forecast. In the world, priority is given to research in this direction, especially to determine the territorial features of population regeneration, improve public health and life expectancy, study the impact of economic and social development of regions on demographic processes. It is also important to determine the unique geodemographic situation due to the influence of natural and economic, socio-geographical and other factors on the population of the regions, factors influencing the development of demographic processes and their territorial characteristics, to improve the scientific basis of regional demographic policy and directions of development, and develop special programs . This article highlights the territorial features of the development of demographic process- es in the regions of the Fergana Valley in 1991-2020, developed forecast parameters up to 2040, and presented important conclusions.

The article deals with the application of qualimetric methods for assessing recreational and tourist potential on the example of an ecotourism cluster developed for natural and geographical and socio-economic conditions and resources of the Ukrainian Black Sea region. The properties of recreational and tourist potential can have different nature, different definitions, and be qualitative-descriptive, verbal, or quantitative (numerical). In qualimetric developments, properties should be comparable in the form of representation and magnitude of evaluation scales. The aim of the study is to develop a methodology for qualimetric assessment of recreational clusters. The theoretical and methodological basis is the fundamental principles and developments of recreational geography, tourism studies and qualimetry, as well as the author’s own developments. In the process of writing, general geographical methods were used, such as descriptive, comparative geographical, and qualimetric assessment methods. Characteristics and properties presented in verbal form can be shown as structural combinations and compounds of simpler indicators. Factors that form the recreational and tourist potential have different weights (significance), which requires an appropriate assessment. The overall assessment of recreational and tourist potential is a weighted average value of all its components, taking into account their weight. The available absolute natural indicators of conditions and resources of recreational and tourist potential are also transformed into qualimetric estimates. The general methodological scheme for assessing recreational clusters, specified according to the conditions and resources of ecotourism of the Black Sea region is represented by seven stages – from structuring a recreational cluster according to its components and levels of hierarchical organization, calculating indicators of the weight of properties and calculating criteria for prop- erties that form the corresponding quality, calculating qualimetric estimates for all primary units of recreational and tourist potential; a meaningful interpretation of the assessment of the recreational and tourist potential of a recreational cluster based on the criteria of properties and scales of the corresponding features and characteristics, as well as indicators of the weight of properties in the formation of recreational and tourist potential. The developed scheme should be considered as a methodological approach for the practical application of qualimetric assessments of recreational and tourist potential in recreational geography and tourism studies.
本文以乌克兰黑海地区的自然、地理和社会经济条件及资源开发的生态旅游集群为例,讨论了评价娱乐和旅游潜力的定性方法的应用。休闲和旅游潜力的属性可以有不同的性质,不同的定义,并且可以是定性的-描述性的,口头的,或定量的(数字)。在定性开发中,属性应该在评估量表的代表性和大小方面具有可比性。这项研究的目的是开发一种对娱乐集群进行质量评估的方法。本文的理论和方法基础是游憩地理学、旅游学和质量测量学的基本原理和发展,以及作者自身的发展。在写作过程中,使用了一般的地理方法,如描述性、比较地理学和质量评价方法。以言语形式呈现的特征和性质可以用简单指示词的结构组合和复合词来表示。形成游憩潜力和旅游潜力的因素具有不同的权重(重要性),需要进行适当的评价。娱乐和旅游潜力的总体评估是考虑到其权重的所有组成部分的加权平均值。现有的娱乐和旅游潜力条件和资源的绝对自然指标也转化为定性估计。根据黑海地区生态旅游的条件和资源,评估娱乐集群的一般方法方案分为七个阶段-从根据其组成部分和层次组织水平构建娱乐集群,计算属性权重指标和计算形成相应质量的属性标准,计算所有主要康乐及旅游潜力单位的质素估计;基于属性的标准和相应特征的尺度,以及属性在休闲和旅游潜力形成中的权重指标,对休闲集群的休闲和旅游潜力评估进行了有意义的解释。拟定的方案应被视为在康乐地理和旅游研究中实际应用康乐和旅游潜力的质量评价方法。
