Soil microbial ecological process and microbial functional gene diversity
土壤微生物生态过程与微生物功能基因多样性

Soil microbes in terrestrial ecosystem carry out a series of important ecological functions, such as geo-ehemieal cycling of elements, degradation of pollutants, and buffering to the acute changes of environment, etc. Soil microbial ecological function has a dose relation with soil function, and the changes in the structure and composition of soil microbial populations can directly affect the realization of soil function. Through their produced enzymes, soil microbes take part in a series of metabolic activities, and the funetional genes of coded enzymes are the functional markers of microbes, in reeent ten years, molecular ecology foeusing on the functional gene diversity has been developed rapidly, whieh gives us a new cut-in point to understand soil microbial eeologieal function from the point of functional gene. This paper reviewed the research advances in the funetional gene diversity correlated to soil microbial ecological funetion, with the perspectives in this field discussed.
