Abstract

The article analyzes the role of the landscape structure of the northeastern Caspian region in the development of geoecological processes. The goal of the study was to conduct geoecological zoning of the northeastern Caspian based on a study of the main factors determining the nature and intensity of the development of modern landscapes and the main geoecological processes: the altitudinal and geomorphological differentiation of the territory that has developed during the long history of the development of the region; significant periodic fluctuations in the level of the Caspian Sea; and development in the region of economic activity, including the oil industry. A map of the spatial differentiation of geoecological processes in the landscapes of the northeastern Caspian was compiled based on their study within various anthropogenic modifications in six key areas. The spatial distribution of geoecological processes in the landscapes of the studied region was determined by direct and indirect deciphering features with synthesized multizonal satellite images from Landsat 5 and 7. Based on this map, a map of the geoecological zoning of the northeastern Caspian region was compiled via geoinformation mapping in the ArcGis 10.3 program. The map contained 25 geoecological regions and 127 subareas—territorial subdivisions (subspecies of modern landscapes) differing by the same type of natural (landscape) and anthropogenic factors of their formation. These factors determine the geographical distribution and the prevalence of certain geoecological processes.

东北里海的地球生态区划

摘要

本文分析了东北里海地区景观结构在地球生态过程发展中的作用。这项研究的目的是在对决定现代景观发展的性质和强度以及主要地质生态过程的主要因素进行研究的基础上,对东北里海进行地质生态分区:已开发领土的海拔和地貌分异在该地区发展的悠久历史中;里海水位的周期性明显波动;以及包括石油工业在内的经济活动领域的发展。根据他们在六个关键区域进行的各种人为改造研究,编制了东北里海景观中地球生态过程空间分异的地图。利用来自Landsat 5和Landsat 7的合成多区域卫星图像,通过直接和间接解密特征来确定研究区域景观中地球生态过程的空间分布。在此地图的基础上,编制了东北里海地区的地球生态区划图通过ArcGis 10.3程序中的地理信息映射。该地图包含25个地球生态区域和127个子区域-区域子区域(现代景观的亚种),它们的自然类型(景观)及其形成的人为因素不同。
