摘　　要：指出了线虫因其特有的生物学特性,在土壤食物网中发挥着重要作用。作为微型土壤动物的关键组成部分,土壤线虫可以通过运动、取食和排泄等生命活动改善土壤结构、疏松土壤、调控土壤微生物群落。同时,线虫对环境敏感度高,能够快速指示土壤重金属污染状况并提供有价值的环境污染信息。阐述了土壤线虫对重金属污染的生物指示作用及其研究现状,提出了线虫作为一种快速的生态毒理指标,能够准确有效地反映土壤受污染状况,具有良好的发展前景。Nematodes play an important role in soil food webbecause of their unique biological characteristics. As key constituent part of soil micro--fauna, nematode could improve soil structure and regulate soil microbial community by means of movement, feeding and excretion. Meanwhile, being sensitive to environmental changes, nematodes could indicate heavy metal pollution of soil and provide valuable information of environmental pollution. This paper discussed the biological indicating function of soil nematode on heavy metal contamination and current studies of nematodes. It is suggested that nematode can be used as a fast ecotoxicological indicator to reflect the soil pollution accu- rately and effectively.
