A pot experiment was conducted to study the effect of Cu contamination on fauna community structure and ecological indicators in soil. With the increase of Cu concentration, the number of soil fauna species and the density of individuals decreased. A negative correlation was found between Cu pollution index (Pi) and soil fauna diversity, species and homogeneous index. All 1232 individuals collected in this research could be classified into 3 phyla, 10 classes, and 16 orders. The dominant genera are Acari, C...
