Abstract

Introduction. Water resources of the Leningrad Region are intensively used to ensure water supply and meet the demands of agricultural and energy industries as well as demands related to navigation, fish farming and recreation activities. The problem of using and protecting small rivers, small lakes, ponds and other natural and artificial links of the hydrological network caused the emergence of “hot ecological spots”. Materials and methods. The paper addresses issues related to anthropogenic impact and accumulation of environmental damage using small rivers of the Leningrad Region as an example. The study is based on current and retrospective data of the authors and third-party researchers, which made it possible to define the development prospects of the water sector in the Leningrad Region. Results and discussion. According to the results of the study, the main type of anthropogenic impact related to economic activity is associated with processing enterprises and urbanization. Besides, for many years, the deterioration of the state of small rivers and watercourses has been determined by their multifaceted use, and with the growing economic stagnation since the 1990s, these problems only have worsened. Conclusion. As a way out, it is possible to improve the management of natural objects. The authors conclude that the management of environmental objects in river catchment areas implies the improvement of economic activity and the direct management of natural objects.

人类活动对列宁格勒地区河流生态状况的影响

介绍。列宁格勒地区的水资源被集中利用，以确保供水，满足农业和能源工业的需求，以及与航运、养鱼和娱乐活动有关的需求。利用和保护小河流、小湖泊、小池塘等水文网自然和人工环节的问题，造成了“生态热点”的出现。材料和方法。本文以列宁格勒地区的小河为例，讨论了与人为影响和环境破坏积累有关的问题。该研究基于作者和第三方研究人员的当前和回顾性数据，这些数据使确定列宁格勒地区水部门的发展前景成为可能。结果和讨论。根据研究结果，与经济活动相关的人为影响的主要类型与加工企业和城市化有关。此外，多年来，小河流和水道状况的恶化是由它们的多方面使用所决定的，随着20世纪90年代以来经济的日益停滞，这些问题只会恶化。结论。作为一种出路，改进对自然物的管理是可能的。作者得出结论，河流集水区环境对象的管理意味着经济活动的改善和自然对象的直接管理。
