草地土壤微生物多样性研究进展

he diversity of soil microbes includes functional diversity, structural diversity and genetic diversity. Currently, the research of soil microbes mainly focuses on forest, fields, grassland, sludge and heavy metal contaminated soil, etc. The research methods including from the traditional culture to modern molecular approaches independent of culture that consists of DGGE/TGGE、T-RFLP、SSCP and RISA, etc, make the study of non-cultured microbes leap qualitatively. The genetic diversity of soil microbes and the composition, structure and succession rules of the populations in grassland can essentially understand the diversity of soil microbes and the relationship with environment. The paper based on related literature data summarizes the research technology and status of soil microbes, and indicates that the future study directions of soil microbes in grassland of China should focus on the effects and response mechanism of soil microbes on the global changes, the ecological function, the evolutionary direction and establishing the soil metagenomic library.
