摘要：在元谋干热河谷采用网扫法调查了云南松林、桉树林、新银合欢林、桉树＋新银合欢林、印楝林及多树种混交的人工林鞘翅目昆虫多样性。结果表明，鞘翅目甲虫标本925号，计71种，分属18个科，其中叶甲科种类最丰富，象甲科数量最丰富。人工林鞘翅目昆虫群落物种丰富度在7～23，Shannon—Wiener多样性指数在1．249～2．562，昆虫多样性总体较低。各样地鞘翅目群落之间为不相似水平。云南松林鞘翅目昆虫群落物种丰富度、Shannon—Wiener指数、Simpson指数及Pielou指数分别为20、2．562、0．104和0．855，其多样性最高，多树种混交林较高，印楝林较低，而桉树林、新银合欢林、桉树＋新银合欢林多样性极低。多树种混交的恢复对昆虫多样性提高有显著促进作用。
By the method of sweep netting, an investigation was made on the beetle （Insecta： Coleoptera） diversity in Pinus yunnanensis , Eucalyptus, Leucaena leucocephala, Eucalyptus ＋ L. leucocephala, Azadirachta indica, and multiple tree species mixed plantations in Yuanmou dryhot valley. A total of 925 beetles were captured, belonging to 71 species and 18 families. Chrysomelidae had most species, while Curculionidae had most individuals. The species richness of the beetle communities was 7 - 23, and the Shannon-Wiener index was 1. 249 - 2. 562, suggesting a lower insect diversity as a whole. Among the test plantations, P. yunnanens/s plantation had the highest diversity of beetle communities, followed by the mixed plantation, A. indica plantation, and Eucalyptus, L. leucocephala , and Eucalyptus ＋ L. leucocephala plantations. The restoration of multiple tree species mixed plantation was of significance in enhancing insect diversity.
