Influencing factors of soil microbial diversity in grassland

Soil microbial diversity of grassland is one of the important issues in grassland ecology. This paper reviewed the advances in researches on influencing factors of soil microbial diversity in grassland, including abiotic factors, human activities and biological factors, and explored the effects of variations on microbial diversity from soil temperature, soil moisture, soil pH, grazing, cultivation, fertilization, vegetation type, plant diversity, community structure, invasive plants and rhizosphere. Finally, future researches of soil microbial diversity, environmental factors and adaptation strategy were discussed which provided scientific basis for the response and adaptation mechanism of grassland.
