摘　　要：主要采用巴氏罐诱法,以四川省九龙县为例调查贡嘎山南麓的鞘翅目昆虫资源。通过4个研究地点、60个样方的调查共采集鞘翅目昆虫标本2036号,隶属29科。隐翅虫科、步甲科的个体、物种数量均最多,属优势类群。在4个研究地点中以洪坝鞘翅目昆虫数量最多,洪坝以25科110种777号标本占据明显优势,是该地区鞘翅目昆虫最为丰富的区域。鞘翅目昆虫群落多样性分析表明,在种级水平上洪坝鞘翅目昆虫的丰富度指数和多样性指数最高:瓦灰山鞘翅目昆虫的优势度和均匀度最高。在科级水平上,洪坝的各项指数在4个研究地点中均最高。虽然鞘翅目昆虫群落组成和数量差异较大,但种级水平相似性系数差异不大,而在科级水平的相似性系数差异较大。各指数随着海拔的升高呈现下降的趋势,这些结果说明该地区的鞘翅目昆虫数量与海拔高度有着密切的关系。We investigated the diversity of Coleoptera on the southern slopes of Mt. Gongga using the bait - trap method. 2036 beetle specimens representing 29 Coleoptera families were captured from 60 plots of four research facilities. Numbers and species of the Staphylinidae and Carabidae were highest. Of the four research facilities, Hongba was richest in Coleoptera, with 777 specimens of 110 species and 25 families. At the species level, Hongba had the highest Coleopteran diversity and richness, while Mt. Wahui had the highest dominance and evenness. At the family level, al I indices of Hongba were highest of the four research facilities. Coleoptera community composition differed between the four facilities, and the similarity coefficients were low at species level, but high at family level. All indices declined with increasing elevation.
