摘要: 对湘江流域工业污染区的土壤动物群落研究表明,接近污染源和污染物质富集的农田,土壤动物的种类和数量减少;工业污染区土壤的污染主要是重金属有毒物质的过量累积。调查共获得29类土壤动物,隶属于4门10纲,动物的种类与数量随着重金属污染程度的增加而递减,土壤动物密度与重金属元素Hg、Cd,zn、Cu、As、Pb的浓度密切相关,这在污染模拟实验中也得到证明。

Abstract: Investigations on soil animal communities in major industrial areas of Xiangjiang River Basin demonstrate that in croplands close to pollution source and abundant in polluted substances, the kinds and amounts of soil animals are distinctly decreased.The pollution of croplands is mainly caused by the accumulation of heavy metals in soil. Through in vestigations, 29 kinds of soil animals are collected, which can be divided into 10 clas ses belonging to 4 phyla. As pollution degree goes up, the kinds and amounts of soil animals are decreased.The density of soil animals has much to do with the concentration of such heavy metal elements as Hg, Cd, Zn, Cu, As and Pb existing in soil , which has been further proved in simulated experiments of soil pollution.
