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.
