In the area of Volga and Ural Sands there are several gas condensate fields, the largest of which is Astrakhan Exploitation of deposits leads to the formation of special technogenic landscape-geochemical systems, where, as a rule, scattering of large masses of substances with a high content of elements occurs, which negatively affect natural complexes. In the arid conditions of the desert, the impact on ecosystems is complicated by limiting factors for living organisms - lack of moisture and poor soil. The results of the study of changes in species composition, geobotanical characteristics, and productivity of plant communities under the permanent influence of the Astrakhan gas complex from 1998 to 2018 are presented. Discusses the importance of validity of the restrictions in the sanitary - protective zone for the recovery of desert vegetation. The increasing role of limiting factors for the vital activity of plant organisms in combination with technogenic loads on ecosystems is shown. The results of determining the above-ground, underground harvest and fall for the spring period from 2005 to 2018 are presented. The conclusion about the formation of stable socio-natural landscapes on the example of the Astrakhan gas complex is made.
