Soil and vegetal shifts in meadows under conditions of alluvial lithogenic matrix on islands in the delta of the Northern Dvina River

In this paper we represent the results of our research: a scheme of plant and soil succession changes on the alluvial lithogenic matrix in the zone of river and marine accumulation in the delta of the Northern Dvina river. We used more than 1000 geobotanical and 200 soil descriptions. The succession scheme of the transformation of meadow communities in the river accumulation zone is represented in this work. This scheme occurs both in the natural processes of phytocenosis and soil development, as well as in agrogenic influence, as well as a number of successional changes during formation of meadows in the zone of marine accumulation.
