为了探明河北小五台山自然保护区蝴蝶种类及其组成,对该保护区的蝶类群落组成及多样性进行了研究.结果表明,小五台山保护区有蝴蝶123种,隶属于7科75属.其中,蛱蝶科的属和物种数种最丰富,为25属49种,占绝对优势;喙蝶科的属数和种数最少,为1属1种.蛱蝶科和眼蝶科的优势种最多,占优势种类的78.57％,构成蝶类的主要优势种群.弄蝶科的物种丰富度指数和均匀度指数最高,分别为1.914 9和0.200 4;蛱蝶科的多样性指数最高,为3.000 8,凤蝶科的物种丰富度指数最低,为0.552 6;凤蝶科的优势度指数最高,为0.866 9.4个不同采集地的蝶类多样性显示,涿鹿杨家坪具有最高的物种数(107种)、个体数(2 020只)和总的多样性指数(3.635 2),涿鹿杨家坪和蔚县金河口的物种相似性系数最高,为0.584 7,共有蝴蝶69种,为中等相似.%To identify the species and compositions of butterflies in Xiaowutai Mountain State National Nature Reserve in Hebei, the community diversity of butterflies thereof was investigated in 4 different sites in 2010. Results show that there were 123 butterfly species belonging to 7 families and 75 genera. Nymphalidae had the most number of genera (25) and species (49), while Libytheidae only had 1 genus and 1 species. Nymphalidae and Satyridae had most dominant species, accounting for 78. 57%, which constituted the main groups in butterfly community. Hesperiidae had the highest richness index (1. 914 9) and evenness index (0. 200 4). Nymphalidae had the highest diversity index (3.000 8). Papilionidae had the highest dominance index (0. 866 9), while Papilionidae had the lowest richness index (0. 552 6) and diversity index (0.552 6). The diversity index, specific richness, dominance index, evenness index and similarity coefficient of the four sites were calculated and analyzed. It is concluded that Yangjiaping had the most species (107), number of individuals (2 020) and highest diversity index (3.635 2). The similarity coefficient of butterfly community between Yangjiaping and Jinhekou was the highest.
