摘　　要：对常熟市虞山林场杨梅园土壤动物群落的构成进行了调查,共获得土壤动物样本1 405个,隶属于4门、7纲、22类。优势类群为蜱螨目和弹尾目2类,占个体总数的90.72%,构成了该地区土壤动物群落组成的主体;常见类群为线虫,占全部土壤动物个体数量的4.76%;其他为稀有类群。3样地环境中土壤动物群落结构分析表明,个体密度为样地3>样地2>样地1;类群数和土壤动物多样性指数(H’)为样地1>样地2>样地3;均匀度指数(J)为样地3>样地2>样地1;优势度指数(C)为样地3>样地2>样地1。不同群落的相似性(q)分析表明,样地1与样地2、样地1与样地3、样地2与样地3的q值均大于0.5且小于0.75,表现为中等相似。土壤动物垂直分布有明显的表聚现象。A preliminary study on the diversity of soil invertebrate communities was conducted at Bayberry Park.A total of 1 405 samples of soil animal was obtained,belonging to 4 phylums,7 classes and 22 taxa.The dominant groups were Acarina and Collembola,which amounted to 90.72% of total individuals and composed the main component of soil animal cluster in the region;Common groups were the Nematoda sorts,amounting to 4.76% of the total.Other types were rare groups.Three kinds of ecological environment of soil animal community structure analysis showed： the density order was artificial plot3plot2plot1;Number of groups and diversity（H＇＇） were artificial plot1plot2plot13;Evenness（J） were plot3plot2plot1;Dominance（C） were plot3plot2plot1.The analysis of the similarity（q） of different group suggested that the similarity（q） of soil invertebratesthe plot1 and plot2,plot1 and plot3,plot2 and plot3 were moderate similar（0.75q0.50）.Vertical distribution of soil invertebrate was concentrated in the surface.
