Abstract:

Saline-alkali soil is an important part of the global ecosystem,and its health and availability are interrelated to the safety of ecology and survival of our human. Soil microorganisms play an important role in soil formation,energy transfer,nutrient mobilization and recycling,vegetation reconstruction and long-term ecosystem stability. Their diversity and distribution are strongly influenced by the geographical environment,composition,physical and chemical properties of soils and plants living on. The microorganisms also could be used as biological additive to improve the saline-alkali soils,conversely. And the input of organic matter is one of decisive value to it. The indigenous microbes with special adaptability that have been domesticated for a long time become the first choice for this work. For the purpose to provide useful information on their ecological functions and application potentials,we analyzed the advances on diversity and function of microbes in saline-alkali soils,the major diversity-affecting factors as well as their application in soil transformation,and then summarized an ecological cycle mode of soil characteristics determine the microbial communities - the microorganisms change soil microenvironment - microbes and soil are in co-evolution.

Key words: saline-alkali soil, microbial diversity, regulatory factors, saline-alkali soil improvement
