摘要/Abstract

摘要： Cd污染对土壤动物影响的模拟实验结果表明,土壤动物群落结构的变化与Cd处理浓度的大小密切相关.在高浓度(99.48mg·kg^-1)组时,土壤动物种类、个体数量、多样性指数、均匀性指数及动物密度均较低;而随浓度降低,各项指标逐渐增加,至低浓度(2.72mg·kg^-1)组时已基本和对照组一致.种类与个体数量和Cd处理浓度的自然对数呈明显负相关.

Abstract: A indoor simulating test showed that there existed a close relationship between the community structure of soil animal and the concentration of soil Cd. When the concentration of soil Cd was high (99.48mg穔g^-1),the species,quantity,diversity index,homogeneous index,and abundance of soil animal were low.With the concentration going down,all indexes above increased gradually.When the concentration of soil Cd was 2.27mg穔g^-1,all the indexes were the same as control.The species and individuals of soil animal were negatively related with the natural logarithm of Cd concentration in soil.
