土壤线虫对环境污染的指示作用

摘要/Abstract

摘要： 线虫作为土壤中型动物区系的一部分,在土壤生态系统中发挥着重要的作用,因其所特有的生物特性,使其广泛地应用于土壤健康状况的指示研究中.根据国内外的研究现状,分别对典型线虫在土壤污染指示与诊断中的应用和线虫群落的各种指数指标法(如成熟指数、多样性指数、相似度指数、关键种法、N/C比值和生理指标法)及其特点进行概述,论述了土壤动物线虫及其对污染环境的生物指示作用,提出土壤线虫作为一种有效的生态毒理诊断指标具有良好的发展前景.

Abstract: 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.

Key words: Nematode, Bioindicator, Environment pollution, Ecosystem, Index
