In this study, the Local Climate Zones (LCZs) in Novi Sad, the second largest city in Serbia, are analysed as to surface temperature differences. The LCZs were delineated on the basis of the GIS-based method created by Geletic & Lehnert (2016). Land Surface Temperatures (LSTs) were derived from the satellites Terra, sensor ASTER, and LANDSAT-8. The thermal images were provided at a similar time (at about 9.30 AM) between 2002 and 2008 (ASTER) and between 2013 and 2017 (LANDSAT-8). Statistical analyses, including the analysis of variance (ANOVA) and Tukey-HSD test, were employed to reveal LST differences between the LCZs. The results indicate that in 84% of cases there were significant differences in LST between pairs of LCZs. Temperature differences between LCZs were the most pronounced in the summer season. In general, 8 (large low-rise), 10 (heavy industry), 2 (compact midrise) and 3 (compact low-rise) LCZs had the highest surface temperatures in Novi Sad. Contrary to this, LCZs A (dense trees), B (scattered trees) G (water bodies) were the coolest zones.
在这项研究中,分析了塞尔维亚第二大城市诺维萨德的当地气候带(lcz)的地表温差。lcz是根据Geletic & Lehnert(2016)创建的基于gis的方法划定的。地表温度(LSTs)数据来源于Terra卫星、ASTER传感器和LANDSAT-8卫星。这些热图像是在2002年至2008年(ASTER)和2013年至2017年(LANDSAT-8)的类似时间(上午9点30分左右)提供的。统计分析包括方差分析(ANOVA)和Tukey-HSD检验,以揭示lcz之间的LST差异。结果表明,在84%的病例中,lcz对之间的LST存在显著差异。lccs之间的温差在夏季最为明显。总体而言,诺维萨德8个(大型低层)、10个(重工业)、2个(紧凑型中层)和3个(紧凑型低层)lcz的地表温度最高。与此相反,lcz A(茂密的树木)、B(分散的树木)、G(水体)是最冷的区域。

The morphological evolution of the fluvial relief in the lowland areas is determined by the dynamic of the lateral channel migration process. River meandering and lateral channel migration represent continuous, dynamic and complex processes, which intensity modifies alluvial plains. Accordingly, it is a current topic observed from the domain of various scientific disciplines and practices, including the geographical aspect of the study. Directly or indirectly, variations of natural and anthropogenic processes affect changes in the lateral migration intensity, which is later manifested through permanent consequences for the environment. The aim of this paper is to investigate the process of lateral channel migration, through the review and interpretation of theoretical and methodological concepts and results of contemporary scientific literature. In this paper, on specific sections of the South Morava River (Serbia), the values of maximum lateral migration over different time periods are determined. Three representative river sectors were singled out, spatial and temporal dynamic was determined, while the process of lateral channel migration was presented quantitatively and graphically. Based on the obtained data, a comparative analysis showed significant riverbank changes for the observed meanders, within the period 1924-2020. Special emphasis is on the analysis of the lateral channel migration in the last decade of the mentioned period. The obtained results can be further used in order to develop and implement plans of water and land management, environmental protection and socio-economic development strategies.
低地河流起伏的形态演化是由侧向河道迁移过程的动力决定的。河流曲流和横向河道迁移是一个连续的、动态的、复杂的过程,其强度改变了冲积平原。因此,这是一个从各种科学学科和实践领域观察到的当前主题,包括研究的地理方面。自然和人为过程的变化直接或间接地影响横向迁移强度的变化,这种变化后来通过对环境的永久性后果表现出来。本文的目的是通过对当代科学文献的理论和方法概念和结果的回顾和解释来研究横向河道迁移的过程。本文以南莫拉瓦河(塞尔维亚)的特定河段为例,确定了不同时期的最大横向迁移值。选取了3个具有代表性的河段,确定了河段的时空动态,并定量、图解地描述了河段横向迁移的过程。根据获得的数据,对比分析表明,在1924-2020年期间,观测到的曲流发生了显著的河岸变化。特别着重分析了上述时期最后十年的侧向河道运移。所取得的成果可进一步用于制定和执行水和土地管理、环境保护和社会经济发展战略的计划。

Weakening of spatial planning system in Serbia - age of prevailing of spatial plans for special purpose areas (2010-2020) 塞尔维亚空间规划体系的弱化——特殊用途区空间规划盛行的时代(2010-2020年)

In the first two decades of the 21st century, the spatial planning system in Serbia underwent a significant transformation following the general trends of change in Serbia. The neoliberal-market model of the economy has directly led to the apparent suppression of social services and of the environmental sector. After 2010, the formerly hierarchical organised system slowly began to marginalise national, regional and local planning. Instead of that, planning of special purpose areas became dominant and almost ubiquitous. This plan, according to the Law, can cover all types of infrastructure, all types of mining, tourist facilities and areas, energy, protected nature objects and cultural and historical monuments, as well as the so-called Belgrade Waterfront and the National Stadium. The paper analyses the causal relationships that have led to the current state of planning, given the systematisation of spatial plans of the special purpose areas so far prepared. Additionally, the paper also discusses the effectiveness of such a partial approach to the field of spatial planning and landscaping in Serbia.
在21世纪的前20年,塞尔维亚的空间规划系统随着塞尔维亚的总体变化趋势发生了重大转变。新自由主义市场经济模式直接导致了对社会服务和环境部门的明显压制。2010年以后,以前的等级组织体系慢慢开始边缘化国家、区域和地方规划。取而代之的是,特殊用途区域的规划成为主导,几乎无处不在。根据该法律,这项计划可以包括所有类型的基础设施、所有类型的采矿、旅游设施和地区、能源、受保护的自然物体和文化和历史纪念碑,以及所谓的贝尔格莱德海滨和国家体育场。本文分析了导致目前规划状态的因果关系,给出了迄今为止编制的特殊用途区域空间规划的系统化。此外,本文还讨论了这种局部方法在塞尔维亚空间规划和景观美化领域的有效性。

An analysis of mean annual runoff was conducted for a small ungauged catchment of the Tulovska River in the South Morava River Basin. Langbein?s method, Turk?s method and regional regression models were applied for obtaining the mean runoff. Long-term mean temperature, annual precipitation and the mean catchment elevation are used as input data. The estimations were conducted using various sources of climatological input data and the results were then compared. Precipitation and temperature data were derived, in a 10 km x 10 km resolution raster data format, from the digital data repository of the CarpatClim project. Point measurements of temperature and precipitation by the Republic Hydrometeorological Service of Serbia were also used as input data and compared with the raster data. The difference between the raster and point meteorological data were attributed to the effects of terrain elevation spatial variability, not captured in the raster data. The analyses showed that the predicted mean runoff can differ up to 50%, depending on the chosen method and the input data.

The paper discusses the geomorphology of the Sunda Trench, an oceanic trench located in the eastern Indian Ocean along the Sumatra and Java Islands of the Indonesian archipelago. It analysis difference in depths and variation in slope steepness between the two segments of the trench: southern Java transect (108.8?E 10.10?S - 113.0?E 10.75?S) and northern Sumatra transect (97.5?E 1.1?S - 101.0?E 5.5?S). The maps and geomorphological modelling were plotted using Generic Mapping Tools (GMT). The data include high-resolution grids on topography, geology, geodesy and geophysics: GEBCO, EGM2008 EGM-2008, GlobSed. The results include modelled segments, slope gradients, and cross-section profiles. The geological processes take place in the Indian Ocean at different stages of its evolution and influence the nature of the submarine geomorphology and geomorphology of the trench that differs in two segments. Java segment has a bell-shaped data distribution in contrast to the Sumatra with bimodal pattern. Java segment has the most repetitive depths at -2,500 to -5,200 m. Sumatra transect has two peaks: 1) a classic bell-shaped peak (-4,500 m to -5,500 m); 2) shelf area (0 to -1,750 m). The data at middle depths (-1,750 to -4,500 m) have less than 300 samples. The most frequent bathymetry for the Sumatra segment corresponds to the -4,750 m to -5,000 m. Comparing to the Sumatra segment, the Java segment is deeper. For depths > -6,000 m, there are only 138 samples for Sumatra while 547 samples for Java. Furthermore, Java segment has a more symmetrical geometric shape while Sumatra segment is asymmetric, one-sided. The Sumatra segment has a steepness of 57.86? on its eastern side (facing Sumatra Island) and a contrasting 14.58? on the western part. The Java segment has a steepness of 64.34? on its northern side (facing Java Island) and 24.95? on the southern part (facing the Indian Ocean). The paper contributes to the studies of the submarine geomorphology in Indonesia.
本文讨论了巽他海沟的地貌,巽他海沟位于印度洋东部,沿着印度尼西亚群岛的苏门答腊岛和爪哇岛。分析了两段海沟的深度差异和坡度变化:爪哇南部样带(108.8?10.10吗?S - 113.0?东经10.75°S)和北苏门答腊样带(东经97.5°S)1.1吗?S - 101.0?E 5.5 ?。使用通用制图工具(GMT)绘制地图和地貌模型。数据包括地形、地质、大地测量和地球物理的高分辨率网格:GEBCO、EGM2008 EGM-2008、GlobSed。结果包括模型段、坡度和截面剖面。地质作用发生在印度洋不同的演化阶段,影响着海底地貌和海沟地貌的性质。Java段具有钟形数据分布,而苏门答腊段具有双峰模式。爪哇段的重复深度最多,为-2,500至-5,200米。苏门答腊样带有两座山峰:1)一个经典的钟形山峰(- 4500米至- 5500米);2)陆架面积(0 ~ - 1750 m)。中深度(- 1750 ~ - 4500 m)的数据少于300个样本。苏门答腊岛段最常见的水深为- 4750米至- 5000米。与苏门答腊段相比,爪哇段更深。对于深度> - 6000 m,苏门答腊只有138个样本,而爪哇只有547个样本。此外,Java段具有更对称的几何形状,而苏门答腊段是不对称的,片面的。苏门答腊岛的陡度为57.86?它的东侧(面对苏门答腊岛)和14.58?在西部。Java段的陡峭度为64.34?北侧(面向爪哇岛)和24.95?在南部(面向印度洋)。本文对印度尼西亚海底地貌的研究有一定的贡献。

The urbanization and globalization phenomenon?s are the most dynamic processes of the modern world. As inevitable, pervasive and irreversible processes, they have a broad and important impact on every day?s life of the societies. Subsequently, the effects of urbanization and globalization on the transformation of existing and the emergence of new touristic objectives in cities have become the topic of scientific debates in recent period. Given that the issue of urban tourism has become relevant during the last three decades, the impact of these processes on the transformation of existing and the emergence of new tourist objectives in urban areas is an unavoidable field of scientific interest. The crucial differences between tourist cities in highly developed and developing countries, as well as between large cities and small towns, further complicates the perception of the complex impacts of urbanization and globalization processes on the phenomenon of urban tourism. These specifics are the main aspects of the development of urban tourism that will be discussed in this paper.
城市化和全球化现象?S是现代世界最具活力的过程。作为不可避免的、普遍的和不可逆转的过程,它们对每一天都有着广泛而重要的影响。社会的生活。因此,城市化和全球化对城市现有旅游目标的转变和新旅游目标的产生的影响成为近年来科学争论的话题。鉴于城市旅游问题在过去三十年中变得具有相关性,这些过程对城市地区现有旅游目标的转变和新旅游目标的出现的影响是一个不可避免的科学兴趣领域。高度发达国家和发展中国家的旅游城市之间以及大城市和小城镇之间的重大差异,使人们更加难以认识到城市化和全球化进程对城市旅游现象的复杂影响。这些细节是本文将讨论的城市旅游发展的主要方面。

Human resource management in environmental protection in Serbia 塞尔维亚环境保护中的人力资源管理
Q4 Social Sciences Pub Date : 2019-12-27 DOI: 10.20944/preprints201912.0361.v1

Starting from the fact that the units of local self-government of the Republic of Serbia are not sufficiently oriented towards innovations related to human resources and the environment, the application of quantitative research tradition examines the positioning and understanding of certain procedures and decisions of human resources management regarding the functioning of the environmental protection system, on the one hand, and future strategies for changing the given system, on the other. A series of 105 face-to-face interviews were conducted during the year of 2016 in 105 of the 191 municipalities in the Republic of Serbia. Examination of the attitudes of the local self-government was carried out using a specially designed closed electronic questionnaire. The results of the multivariate regressions show that the most important predictor of the possible improvement of the environment is the size of the municipality. The remaining variables (e.g., human resources policy, human resources service) did not have significant effects on the ability to improve the environment. In more than half of local self-governments, there was no clearly defined human resources strategy in the field of environmental protection, an environmental protection service, an Environmental Action Plan, as well as an employment plan for waste management in local governments, etc. The research has shown that top managers of local governments agree that the management of human resources in environmental protection represents a significant opportunity to improve the quality of the environment. The results of the research can be used to improve the organization of human resource competence in environmental protection and the quality of a working and sustainable environment in the area of local self-government.
从塞尔维亚共和国地方自治单位没有充分面向与人力资源和环境有关的创新这一事实出发,定量研究传统的应用一方面审查了关于环境保护系统运作的人力资源管理的某些程序和决定的定位和理解,另一方面审查了改变现有系统的未来战略。2016年,在塞尔维亚共和国191个市中的105个市进行了105次面对面访谈。对地方自治政府的态度进行了调查,使用的是专门设计的封闭式电子问卷。多元回归结果表明,城市规模是影响城市环境改善的最重要因素。其余变量(如人力资源政策、人力资源服务)对改善环境的能力没有重大影响。半数以上的地方自治政府在环境保护领域没有明确规定的人力资源战略、环境保护服务、环境行动计划以及地方政府废物管理的就业计划等。研究表明,地方政府高层管理者一致认为,环境保护中的人力资源管理是改善环境质量的重要机会。研究结果可用于改善地方自治区域环境保护人力资源能力的组织和工作环境和可持续环境的质量。

This paper presents the results of a survey conducted among members of the second generation of Serbian migrants born in Switzerland. Thanks to the data obtained through the application of qualitative research, there are presented activities of the respondents in the transnational area. Their engagement on the route between Serbia and Switzerland is reflected in four areas of transnationalism: direct/indirect contacts, transnational engagement in the receiving state, remittances and visits to the country of origin and return plans. The results indicate that children of migrants who come from a family whose members are active in a transnational space, in most cases, adopt the same norms of behavior and it plays a crucial role in the process of identity formation. However, their transnational behavior on the relationship between the two states has different form, and the transnational activities examined do not condition each other.
本文介绍了在瑞士出生的第二代塞尔维亚移民成员中进行的一项调查的结果。通过应用定性研究获得的数据,呈现了受访者在跨国领域的活动。他们在塞尔维亚和瑞士之间的路线上的参与反映在跨国主义的四个方面:直接/间接接触、在接受国的跨国参与、汇款和访问原籍国以及返回计划。研究结果表明,家庭成员活跃在跨国空间的移民子女在大多数情况下采用相同的行为规范,这在身份形成过程中起着至关重要的作用。但是,它们的跨国行为对两国关系的影响有不同的形式,而且所考察的跨国活动并不互为条件。

The period of returning the people to religion, that is evident in the last two decades, increased the number of the pilgrimage tours all over the world, including the Republic of Serbia. This research is oriented towards determination of different motives of Orthodox Christian Church Pilgrims from Serbia for visiting two monasteries important for Serbian medieval cultural heritage, catalogued on the UNESCO World Heritage List, the Monastery Visoki Decani and the Monastery Pecka Patrijarsija, as monasteries of high cultural and historical importance, with rich traditional spirituality, authentic architecture and fresco painting heritage. Both monasteries have significant role in the religious life of Serbians, but they also represent important symbols of the national identity among the Serbian people. Nowadays, the pilgrimage tours for visiting these monasteries are occurring in difficult conditions for Serbian citizens, due to the problem related to the safety and security situation and political conditions. This research was conducted in order to identify are there differences in pilgrims? motivation for travelling, according to their socio-demographic characteristics. Thus, the focus on researching the motives of Serbian citizens for conducting the pilgrimage tours to these monasteries is significantly enhanced by the fact that visits to these monasteries involve even a risk for the life safety among the Serbian pilgrims. For conducting the research, we used the questionnaire with the identified 6 factors as possible motives for the pilgrimage.
在过去二十年中,人们回归宗教的时期明显增加了世界各地朝圣之旅的次数,包括在塞尔维亚共和国。这项研究的目的是确定来自塞尔维亚的东正教朝圣者访问两个修道院的不同动机,这两个修道院对塞尔维亚中世纪文化遗产很重要,被列入联合国教科文组织世界遗产名录,Visoki Decani修道院和Pecka Patrijarsija修道院具有很高的文化和历史重要性,具有丰富的传统精神,真实的建筑和壁画遗产。这两座修道院在塞尔维亚人的宗教生活中发挥着重要作用,但它们也代表了塞尔维亚人民民族认同的重要象征。现在,由于安全局势和政治条件的问题,前往这些修道院的朝圣之旅对塞尔维亚公民来说是在困难的条件下进行的。这项研究是为了确定朝圣者之间是否存在差异?旅游动机,根据他们的社会人口特征。因此,由于参观这些修道院甚至会危及塞尔维亚朝圣者的生命安全,因此研究塞尔维亚公民前往这些修道院朝圣的动机的重点就大大加强了。为了进行研究,我们使用问卷调查,确定了6个因素作为可能的朝圣动机。

Changes in precipitation over the East Herzegovina region 东黑塞哥维那地区降水的变化
Q4 Social Sciences Pub Date : 2019-01-01 DOI: 10.2298/GSGD1901029P

Changes in annual and seasonal precipitation over the East Herzegovina region in Bosnia and Herzegovina during the 1961-2016 periods were analyzed based on data sets of daily precipitation from 14 meteorological stations and rainfall gauges. The results show a downward trend in annual precipitation over the entire East Herzegovina region. Seasonal trend analysis showed that negative trends prevailed throughout the year, except in autumn season. Most prominent negative trends were registered in summer season throughout the region. In winter and spring season, precipitation displayed trends of both sign (although a downward trend prevailed). In the autumn season, precipitation has increased almost throughout the entire East Herzegovina region. However, a majority of estimated trends in annual and seasonal precipitation were weak and statistically insignificant. Prevailing negative values of the Rainfall Anomaly Index since the 1990s also suggest that precipitation reduction was present over the East Herzegovina region. Analysis of the Cumulative Precipitation Anomalies showed that a dry period started in 1981 and still continues. Precipitation variability was strongly dictated by the large-scale atmospheric circulation patterns over the Northern Hemisphere, such as the North Atlantic Oscillation, the East Atlantic/West Russia pattern and the Arctic Oscillation, particularly during winter season.
利用波黑东部地区14个气象站和雨量计逐日降水资料,分析了1961-2016年波黑东部地区年降水和季节降水的变化特征。结果表明,整个东黑塞哥维那地区的年降水量呈下降趋势。季节趋势分析表明,除秋季外,全年均为负趋势。整个区域夏季出现了最显著的消极趋势。冬季和春季降水均呈现两种趋势(但以下降为主)。在秋季,几乎整个东黑塞哥维那地区的降水都增加了。然而,大多数年和季节降水的估计趋势都很弱,在统计上不显著。20世纪90年代以来降水异常指数的普遍负值也表明东黑塞哥维那地区降水减少。对累积降水异常的分析表明,1981年开始出现旱季,旱季仍在持续。降水变率受到北半球大尺度大气环流模式的强烈影响,如北大西洋涛动、东大西洋/西俄罗斯模式和北极涛动,特别是在冬季。
