【摘要】 线虫是土壤中最为丰富的无脊椎动物,在土壤生态系统腐屑食物网中占有重要地位.由于线虫具有形态特殊、分离鉴定相对简单,以及对环境变化敏感等特点,现已被作为模式生物用于生态毒理学研究,为环境污染评价提供有价值的信息.论文系统阐述了土壤线虫在物种和群落水平的生态毒理学研究现状,指出了目前线虫毒理学研究存在的薄弱环节,并对今后的研究趋势进行了展望.更多还原

【Abstract】 Soil nematodes are the most abundant invertebrates,and occupy important positions in soil detritus food web.Due to their special features,such as stereotyped behavior pattern,easily to be identified,and sensitivity to environmental changes,soil nematodes have been used as model organisms in ecotoxicological research to evaluate environmental pollution.This paper summarizes the present situation of soil nematode ecotoxicology at species and community levels,and points out the weakness for the application of soil nematodes in ecotoxicological study.Finally,the research trends in the future are discussed.更多还原
