摘　　要：从2003年11月到2004年10月对洞庭湖湿地平原、丘岗、低山的4种生态系统中的小型节肢土壤动物群落的组成、多样性、相似性进行了比较研究。全年调查共获得小型节肢土壤动物27641个,隶属节肢动物门的6纲、24目。4个土壤动物群落中动物类群数和个体数均以针阔混交林>茶林>竹林>阔叶林;多样性指数(H')由大到小依次是针阔混交林>茶林>阔叶林>竹林,与群落均匀度的变化显著相关,而与群落的丰富度关系不密切;Jaccard系数、Gower系数和Pianka的α指数的分析结果表明,4种群落中共有的类群数极为相似,但群落中各类群的最大个体数和最小个体数的差值相差很大。Between Nov;2003 and Dec,2004,a comparative study was conducted on the community composition, similarity and number of arthropods of four different ecological systems in the plain and hilly areas of Dongting wetland . A total of 27641 heads of arthropods were found,belonging to 24 orders of 6 classes . Four types of forests had different number distributions of both communities and individual heads . （From the biggest to the smallest） they were mixed needle and broad leaf , camellia ,bamboo and broad leaf forests . The variety of index （H＇） （from the biggest to smallest） was distributed as follows ： mixed needle and broad leaf, camellia broadleaf and bamboo forests . this is closely correlated with the erermess,but not so with the riches of the communities . An analysis of Jaccard, Gower indices and Plank＇s a index shows that the number of types is similar in the four communities,but the difference between the biggest and smallest numbers of individual heads is great.
