摘　　要： 本次研究共捕获土壤动物155只,分别隶属4门10纲18类.研究结果显示:样本中优势类群4类,常见类群7类,稀有类群7类;秋冬季所捕获的土壤动物类群数相同,但其他群落结构指标存在差异;秋冬季节乔木林下土壤动物类群和个体数表聚性明显;冬季土壤动物类群数和个体数逐层递减;线虫的季节动态在很大程度上决定了群落的季节动态. 155 soil animals, which belong to 4 phylum, 10 Classes, 18 kinds, were captured. The results show that there are 4 of predominant group, 7 of common group, 7 of rare group; the numbers of soil animal groups captured in fall and winter were the same, but there are differences in index of other community structure; it is obvious of the surface accumulation of group and individual number in fall and winter seasons under the arbor forest; group and individual number of soil animal decreases with layers in winter; Seasonal dynamics of nematode determines, to a large extent, the seasonal dynamics of community.
