Abstract:

In order to understand the structural features of the soil animal community of artificial grass in Chongming Island,Ying Tung Ecological Village Holiday villa,from June,2011 to March,2012, a detailed fourseason investigation was conducted on the soil animal community under the artificial grass in Ying Tung Ecological Village,Chongming Island,by taking the nearby natural bushes.The result shows as follows.（1）The soil animals in the artificial grass of Ying Tung Ecological Village included 4 phyla,10 classes and 15 groups,in which Nematoda,Rotifers,and Planarian were the dominant groups,and the common groups were Oligochaeta,Acarina,Collembola,Diptera larvae,and other 16 types were rare groups.（2）As the soil depth increased,the group and individual numbers of soil animal showed surface convergence phenomenon in the artificial grass of Ying Tung Ecological Village.Simultaneously,the seasonal surface convergence phenomenon showed difference.(3)The DG Index had a better performance in the changes of community composite index than the ShannonWiener Index.The soil animal community was high in autumn,low in summer. Based on the statistical analysis of various indexes,the soil environment was constantly updated,and soil animal community diversity was in the recovery stage
