土壤重金属污染的微生物生态效应研究进展

对近年来土壤重金属污染微生物生态效应的研究进展进行了归纳总结,主要从微生物群落特性和微生物生理、生化参数等几个方面进行了阐述.重金属污染土壤后,尤其是高浓度的重金属污染对微生物生物量和群落结构都有破坏作用,但由于微生物群落结构的复杂性和研究方法的片面性,一直是研究的热点和难点,开发更加简便、直接的方法将是对这方面研究的突破.同时,微生物的生理、生化参数是从另一侧面反映重金属污染对微生物的影响,它是对微生物群落特性研究的有利补充,所以不同方法的合理选择和搭配是实验取得预期结果的关键因素之一.

Ecological effect of heavy metals in soil on microbes

Ecological effect of heavy metals in soil on microbes was studied in recent years, and this article summarized the main results. Microbial community structure, physiological and biochemical parameters were chiefly studied. For heavy metals pollution, especially high concentrations, microbial biomass and community structure had negative effects. However, microbial community structure is a complex system and corresponding methods are not very perfect, which brought difficulty to study. Pay more attention to getting simple and direct methods will help to solve this problem. Meanwhile, microbial physiological and biochemical parameters were favorable supplement to microbial community structure for heavy metals pollution, a good choice and appropriate arrangement of methods would be one of the helpful factors to study successfully.
