2004年10-11月对金华市市区8种城市绿地生境中的大型土壤动物群落进行了调查, 共获得大型土壤动物1231只, 隶属3门8纲20目。其中优势类群为近孔寡毛目、膜翅目、双尾目和蜘蛛目, 常见类群为正蚓目、等足目、柄眼目、鞘翅目、鳞翅目、双翅目和同翅目, 其余类群为稀有类群。不同城市绿地生境中的土壤动物的类群组成以及个体数不同。在土壤动物研究中, 群落复杂性指数(C)比Shannon-Wiener指数(H′)更能体现群落的复杂性与多样性, 且能修正不同类群个体数对多样性的影响。大型土壤动物显示了明显的表聚现象, 垂直分布有明显差异, 类群数和个体数随深度增加而减少。群落聚类以及排序的结果显示, 8种城市绿地生境中的大型土壤动物群落可以分为6大类: 草坪类、草地类、新植草坪类、无草本层的人工林类、有草本层的人工林类和灌木林类。

From October to November, 2004, we investigated eight soil macrofauna communities from urban greenbelts at Jinhua City, Zhejiang Province. We found a total of 1231 soil macrofauna individuals, belonging to 20 orders, 8 classes, and 3 phyla. The dominant orders were Plesiopora, Hymenoptera, Diplura, and Araneida, while the frequent orders were Lumbricida, Isopoda, Stylommatophora, Coleoptera, Lepidoptera, Diptera, and Homoptera, and others were rare orders. The compositions and the quantities of soil macrofauna communities differed in different habitats. We found that the complexity index of community (C) was better than the Shannon-Wiener index (H′) in indicating the complexity and diversity of the communities, and it could adjust for the influence of the number of individuals. The vertical distribution of soil macrofauna showed obvious surface assembly phenomenon. Using the hierarchical cluster and non-matric multi-dimentional scaling methods, the eight communities were classified into six groups: the turf group, grassland group, new turf group, man-made hurst with herbage group, man-made hurst without herbage group, and suburban shrubbery group. The hierarchical cluster and the non-matric multi-dimentional scaling ordination are suitable for analyzing biodiversity differences among soil fauna communities.
