摘要：

为研究25~35年茶树种植区域土壤动物组成结构及多样性特征。对常熟市虞山林场茶园土壤环境进行了调查，共获得土壤动物样本1095个，隶属于4门7纲27类。优势类群为线虫、蜱螨目和弹尾目3类，占个体总数的88.18%，构成了该地区土壤动物群落组成的主体；常见类群为蜘蛛目、原尾目、膜翅目幼虫和鳞翅目幼虫4类；其他为稀有类群。三样地环境中土壤动物群落结构分析表明：个体密度依次为茶园2＞茶园1＞茶园3；类群数依次为茶园1＞茶园3＞茶园2；多样性指数(H’)依次为茶园3＞茶园1＞茶园2；均匀度指数(J)依次为茶园3＞茶园2＞茶园1；土壤动物优势度指数(C)依次为茶园1＞茶园2＞茶园3。茶园中三样地不同群落的相似性(q)分析表明：茶园1与茶园2、茶园1与茶园3、茶园2与茶园3的q值均在0.5＜q＜0.75之间，均表明相似水平为中等。茶园中土壤动物垂直分布特征表现为具有明显的表聚现象。

Abstract:

In order to study Diversity of soil invertebrate communities of 25-30 years of tea planting area. A preliminary study was conducted at Tea Park Yushan Hill, a total of 1095 soil animal belonging to 4 phylums, 7 classes and 27 taxa. Among them, the dominant groups werer Nematoda, Acarina and Collembola, which amounted to 88.18% of total individuals; Common groups werer the Araneae, Protura, Hymenoptera and Lepidoptera sorts, amounting to 7.31% of total, other was rare groups. Three kinds of ecological environment of soil animal community structure analysis showed: the density were Tea Park 2＞Tea Park 1＞Tea Park 3; Number of groups were Tea Park 1＞Tea Park 3＞Tea Park 2; diversity(H') were Tea Park 3＞Tea Park 1＞Tea Park 2; Evenness (J) were Tea Park 3＞Tea Park 2＞Tea Park 1; Dominance (C) were Tea Park 1＞Tea Park 2＞Tea Park 3. The results also showed that similarity (q) of soil invertebrates The Tea Park1 and Tea Park 2 , Tea Park 1 and Tea Park 3, Tea Park 2 and Tea Park3 were moderate similar (0.75＞q＞0.50). Vertical distribution of soil invertebrate are concentrated in the surface.
