摘　　要：2003年11—12月，采用样线调查方法对云南铜壁关自然保护区的4种代表性生境类型进行了昆虫多样性调查，鉴定标本6633号，隶属10目89科463属783种，昆虫区系具有典型的东洋区特征．89个科中，叶甲科Margalef物种丰富度指数最高，蚁科、瓢虫科次之．保护区昆虫以小种群的方式存在，783个种中相对多度低于1‰的昆虫物种有468种．分别用Shannon—Wiener指数（H＇）、Simpson优势度指数（D）、Pielou均匀度指数（Jsw）和Margalef物种丰富度指数（dMa）对4种生境类型进行统计分析，结果表明，类型1（季节雨林）的H’、D、Jsw最高，类型2（山地雨林）的dMa最高，类型4（中山湿性常绿阔叶林）的H’、D、Jsw、dMa最低，说明昆虫多样性与生境植物种类的丰富程度、海拔高低密切相关．Insect diversity had been investigated by route method in 4 types of representative habitat of Tongbiguan Nature Reserve in Yunnan province during November to December of 2003. There have totally been 6633 specimen identified, accounting for 783 species, 463 genera, 89 families and 10 orders. The insect fauna had typical oriental characteristics. Among 89 families, the richness index of Margalef species was the highest, Formicidae family and Coccinellidar family followed by in order. The insects existed in small population in this reserve. Of the 783 species, there was 468 insect species less than 1%o in terms of relative abundance. In addition, four types of habitat were statistically analyzed by Shannon- Wiener Index （H＇）, Simpson Dominance Index （D）, Pielou Evenness Index （J sw） and Margalef Species Richness Index （dMa） respectively. The results revealed that Type One （seasonal rain forest） had the highest H＇ , D and Jsw Type Two （mountain rain forest） had the highest dMa,while Type Four （ mid -mountain humid evergreen broadleaved forest） had the lowest H＇, D, Jsw, dMa All these illustrated that insect diversity was closely interrelated with the richness of plant species in the habitat and the elevation as well.
