Abstract:

In order to discuss the composition and community diversity of soil harmful animals,and their relationship with soil environmental factors in different vegetation types,we chose two sites which located in the opposite side of the out ring expressway in green belts at Shanghai Outer Ring Expressway.The soil animals were collected in litter layer and 0～15 cm of soil in 4 seasons during the study period from November 2007 to July 2008.A total of 359 soil harmful animals were collected,belonging to 8 orders and 23 families.242 soil harmful animals were collected in litter layer,belonging to 7 orders and 19 families,in which the dominant groups were Formicidae，Phlaeothripidae，Persimmon Scales.And 117 soil harmful animals were collected in soil layer,belonging to 4 orders and 8 families.The dominant group was Formicidae in soil layer.The deciduous broadleaved forest showed higher group number,density and community diversity than deciduous coniferous forest and evergreen broadleaved forest.There was significant difference between pH and total nitrogen.The density of major groups were clearly relative to total nitrogen and total total phosphorus(〖WTBX〗p<005〖WTBZ〗).〖
