Abstract: 

The article presents the results of the geo-ecological state analysis of steppe landscapes of oil and gas fields within the Volga-Ural oil and gas province. As a key parcel were selected polygons with an area of around 100 sq. km each. The digitization of key sites of oil and gas objects location and road transport network has been executed. It has been shown that the most large-scale and widespread changes are disturbances of soil and vegetation cover, which occur as a result of the introduction and operation of the area and linear infrastructure of fields. It has been revealed that significant amount of oil and gas objects in the area of research are located in the unsuitable areas from the point of view of landscape-morphological conditions. Common violation that can cause long-term critical consequences is also the placement of objects near watercourses.
