摘　　要：2006年对江西武夷山自然保护区4个地区徐家厂、侗木关、十四公里和黄岗山进行地表甲虫群落组成多样性的调查，共设样地22块，主要采用巴氏罐诱法。采到标本1625号，隶属16科。以隐翅虫科数量最多，占数的31．0％，步甲科次之，占22．6％，叩甲科、叶甲科和金龟子科的数量各占5％以上，它们共同构成该地区地甲虫的优势类群。徐家厂甲虫的个体数量、多样性指数和丰富度指数最高，黄岗山的均匀度指数最高。4个地区虫群落的相似性指数均处在0．25～0．50之间，为中等不相似水平。几种常见甲虫在阔叶林、针阔混交林、针叶林高山灌丛这4种生境内的数量分布有显著差异。整个鞘翅目在针叶林内的个体数量最多，高山灌丛内的最少。指数随海拔的升高出现不同变化。这些结果说明江西武夷山自然保区的甲虫数量与生境有密切关系，海拔高度其多样性有一定影响。The diversity of litter-layer beetles was investigated in Wuyishan Nature Reserve. Four areas were selected, Xujiachang, Tongmuguan, Shisigongli and Huanggang-Mountain. We built up 22 plots mainly using pitfall traps. 16 beetle families were found among the 1625 captured specimens, of which 31.0% was Staphylinidae and 22.6% was Carabidae. Elateridae, Chrysomelidae and Scarabaeidae were each above 5% of the total. Xujiachang had the highest individual num- bers, diversity （H＇） and richness （S）. Huanggang-Mountain had the highest evenness （J）. The similarity coefficient （q） of the four areas was between 0. 25 - 0. 50, which means these areas were middling dissimilar. All beetles of Coleoptera were the most abundant in coniferous forest, but were the rarest in shrubs. With the elevation growing up, the indices changed differently. All the results show that habitat has close relation with the number of litter-layer beetles. Elevation may influenee its diversity.
