- Аннотация: The ecosystem of the Lower Volga exists and grows depending on the variable and peculiar mode of the river Volga. The levels of floods and their duration are directly dependent on the flow of the Volga and the level of the Caspian Sea. In the period of intense uplift of the Caspian Sea and the Volga flow increased the height of spring-summer floods and their duration significantly increased, which caused the redistribution of soluble salts in the soil. Adapting to such a mode of soil when the soil depending on the location and the intensity of floods is salinizated or desalinizited, on this part of the delta the unique biocenosis forme. The observations carried out by the authors, suggest that changes in the structure and thecomposition of the plant communities have a directional character. During the lowering of the Caspian Sea and the low flood the halophytizatongrass occurs, and with increasing water content of the area (and reducing the salt content) of the soil are as in flood plain...
