摘　　要：土地质量评价指标体系成为当前的研究热点,而土地污染是影响土地质量的重要因素。为了对土地质量全面客观地进行评价,提出了土壤动物指标可以作为土地污染的一个间接指标。文章认为土壤动物与土地污染之间存在着密切的关系,并表现在土壤动物各个生物组织层次中:在土壤动物体内累积污染物,在个体层次上表现为毒理学影响,在种群和群落层次上表现为生态学影响。通过对比被污染土地中土壤动物各项指数与未污染土地中土壤动物各项指数,综合得出土壤动物指标,并以此指标作为土地污染的替代指标。Land quality indicators become a hot issue recently and land pollution is an important factor influencing land quality. We suggest soil animal indicator as a substitute indicator for land poUution. It is evident that there exists a consanguineous correlation between the degree of land poUution and the indices of soil animals in four organization levels of soil animals, i.e. in the body of soil animals - bioaccumulation, in the individual level - toxicological impact, in the population and community level -ecological impact. The soil animal indicator served as a substitute indicator for land pollution is derived from comprehensively comparing the indices of soil animals in polluted land with that of soil animal in poUution- free land.
