Soil nematode as a bioindicator of environment pollution
土壤线虫对环境污染的指示作用

As a part of mesofauna in soil ecosystem,nematode plays an important role in essential soil processes.Because of its unique attributes,nematode was widely used in the study of soil health indication.Based on the current studies at home and abroad,this paper discussed the function and application of nematode in indicating and diagnosing soil pollution,and the indices (maturity index,diversity index,similarity index,key species,N/C ratio,and physiological index) and their characteristics of nematode communities used as indicators.As a useful index of bioindicators in ecotoxicological diagnosis,the prospect of soil nematode application was of potential.
