Identification of successional stages of vegetation is a necessary part of work on the identification and prediction of impact to the ecosystem of the Volga River delta, which in turn is necessary for recommendations to improve the stability of the delta region. Currently, in the Volga delta and assessment of environmental changes is urgently required for sustainable and environmentally sound development of the region due to the ongoing changes of the hydrological regime, climate, and human activities. These essential elements of this evaluation are the organization and management of soil and vegetation monitoring. There are the results of monitoring soils and vegetations in grassland low delta of the Volga River in this article from 1979 to 2011. The influence of some meteorological (average annual air temperature, air temperature and the amount of precipitation during the growing season), hydrological (the average amount of water flow and volume of flow for the II quarter) and anthropogenic (human activities) factors on the dynamics of the content of soluble salts in the soil and toxicity of the soil solution, as well as the productivity and species composition phytocenoses of the middle delta of the Volga River.
