Correlation between characteristics of Reaumuria soongarica communities and soil factors in the Sangong River basin

Abstract

Reaumuria soongarica is one of the most widely distributed plant species in arid regions of China and has an important role in maintaining the stability of the desert ecosystem. On the basis of field data, including the species composition, number of species, plant height, coverage and abundance, and selected soil properties (electrical conductivity, pH, bulk density and moisture content) , the fine root biomass and aboveground biomass of two R. soongarica communities in the Sangong River basin were investigated over the course of the main growing season (from June to
