水污染对土壤动物群落结构的影响

Effect of water pollution on soil animal community structure

以芜湖市经济技术开发区为例,通过对比的方法,对5种不同水污染所造成的土壤动物群落结构的变化进行了取样调查,在5种生境中共取10个样方,获得土壤动物1333个,其中优势类群为螨、弹尾、蚯蚓和线蚓;由于水污染源的不同,各生境土壤动物的种类和数量也随之发生变化,土壤动物群落的多样性、均匀性、优势度几个重要指标存在很大差异,垂直分布出现逆分布现象。

Through sampling among economic-technical developing area in Wuhu city about changes of five group structures caused by different water pollution; specimens and 1333 soil animals were acquired, in which mite, earthworm, etc were dominant positions;the variety and quantity of soil animals, as well as some important indexes of every group, changes with different sources of water pollution..
