摘　　要：对桉树人工林系统昆虫种类进行调查和鉴定,记录了桉树人工林昆虫种类共有16目63科106种.从群落物种数来看,鞘翅目的物种丰富度最高(20.56%);从物种的个体数量看,鳞翅目昆虫的数量最多(30.71%);桉树林昆虫总的群落多样性指数为1.393 3,均匀性指数为0.930 1,鞘翅目的群落多样性指数(0.293 7)和均匀性指数(0.210 8)都最大.文中就昆虫群落多样性与稳定性的关系以及如何抑制害虫发生等问题进行了讨论.The survey and identification of insect species in Eucalyptus plantation have recorded 106 insect species, belonging to 63 families and 16 orders. In term of species quantity of the community, the richness of Coleoptera is the highest as 20.56% ; in term of individual quantity, Lepidoptera is the largest as 30.71%. Generally the community diversity index is 1. 3933 and evenness index is 0. 9301. In detail, Coleoptera ＇ s diversity index as 0. 2937 and evenness index as 0. 2108 are the biggest. The paper discusses the relationship between diversity and stability as well as the measures for controlling destructive pests.
