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
Fine roots comprise plant roots with a diameter less than 2 mm and are important for plant growth and development, the soil carbon pool, and the global carbon cycle. In this research, sequential soil coring and ingrowth bag methods were used to investigate the fine root dynamics and turnover (formation, senescence, death and decomposition) of two Reaumuria soongarica communities with different physiognomy characteristics from May to October 2010 (representing the whole growing season) in the Sangong River basin. The fine root distribution, selected soil properties (such as moisture content, pH, and electrical conductivity) , community structure, fine root decomposition rate, and fine root turnover of two R. soongarica communities were measured. Stepwise regression analysis was used to reveal the relationship between fine root
Litter production and decomposition of different forest ecosystems and their relations to environmental factors in different climatic zones of mid and eastern China.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
