摘要：
The results showed that the salt content in the top soil layer drops and the productivity of the aboveground plant mass rises in the middle part of the Volga River delta. It was revealed that the horizontal migration of populations of plant species is significant and their shift along the height gradient is slight. This may be related to a rise in soil moistening, changes in the agricultural use of the aboveground biomass, or a possible effect of acid precipitation. © 2015, Pleiades Publishing, Ltd.
