摘要
为了解不同利用方式土地的大型土壤动物群落结构,于2004年10—11月对浙江省金华市市区北部7种土地,即农田(P)、菜园(K)、果园(O)、荒地(W)、庭院(Y)、草皮绿地(L)和建筑工地(B)进行垂直(上、中、下3层)取样,共获得大型土壤动物1161只,隶属3门8纲20目。分析表明:大型土壤动物群落优势类群为近孔寡毛目、膜翅目,常见类群为蜘蛛目、双尾目、正蚓目、等足目、柄眼目、鞘翅目、鳞翅目和双翅目,其他均为稀有类群。大型土壤动物群落的群落复杂性指数(C)为O>K>W>B>L>P>Y,Shannon-Weiner指数(H′)为L>B>W>K>O>P>Y,C比H′更好体现了群落的复杂性与多样性。垂直分布显示大型土壤动物具明显的表聚现象。根据大型土壤动物群落聚类和排序的结果,可将7种土地分为3组,即强干扰无植被组、草本种植组和果园组,显示了大型土壤动物对不同土地利用方式的响应情况。
From October to November 2004 by using a sampling method, we investigated the soil macrofauna communities at 7 using types of soils, paddy field (P), kaleyard (K), orchard (O), wilderness (W), yard (Y), lawn (L) and building site (B) in Jinhua, Zhejiang. There were 1 161 soil macrofauna individuals belonged to 20 orders, 8 classes, and 3 phylums in total samplings. The dominant orders were Nematoda and Hymenoptera, the frequent orders were Araneae, Diplura, Lumbricida, Isopoda, Stylommatophora, Coleoptera, Lepidoptera and Diptera, and then the remnant orders were rare orders. the complexity index of community (C) tended O>K>W>B>L>P>Y, and Shannon-Weiner index (H′) L>B>W>K>O>P>Y. C was manifested better than H′ in representing the complexity and the diversity of communities. The vertical distribution of soil macrofauna had obvious surface assembly. Using the Hierarchical Cluster and the Non-matric Multi-dimensional Scaling method, the 7 communities were classed to 3 groups: highly disturbing and non-bestrow group, herbage growth group and orchard group, which shows the response of soil macrofauna communities to the different soil using types.
