The biodiversity of soil macrofauna were surveyed by sampling five quadrats(20 cm×20 cm)in 5 green-lands (poplar wood,rapeseed farm,grassland in park,nursery,and lawn)at Yancheng City in spring,2011. The habitat of poplar,grassland in park and nursery had a higher value of α biodiversity which characterized by density-group index(DG),complexity index(C)and Shannon-Wiener biodiversity index(H'),while habitat of rapeseed farm and lawn had a lower value. A significant linear correlation was found between DG index and C index(P<0.01,n=5). Based on the β biodiversities(Jaccard’s similarity coefficient),we made Hierarchical Cluster analysis and the results of that the soil macrofauna communities can be divided into two groups formed by habitat of poplar,grassland in park,and nursery as one group,rapeseed farm and lawn group as the second group. Our results indicated that the biodiversity of soil macrofauna communities is related to the complexity of habitat characters. The distribution of trees might be an important factor that influenced on the soil macrofauna communities in green-land. The biodiversities variation among different green-lands can provide help in green-lands design in the cities.
