We examine the ecologo-hydrological characteristics of the transboundary basin of the Ural river. We highlight the main water-ecological problems facing the basin and determine the territorial features peculiar to them. The prospects for cooperation between nations within the framework of institutional collaboration are considered. 相似文献

This paper reports on the geoecological state of landscapes of oil and gas fields in the Ural–Volga steppe zone. Large-scale direct disturbances and impacts with dramatic aftereffects have been revealed on the basis of field research using the geographic information system (GIS) and data from remote sensing of the Earth. It has been shown that the current land-use pattern in oil and gas production areas is in need of professional control to protect and recover the landscapes in the steppe zone.
