By the methods of fixed point, line intercept, and random investigation, the vertical distribution and community diversity of butterflies in Yaoluoping National Nature Reserve were investigated from 2005 to 2008. A total of 3681 specimen were collected, belonging to 111 species, 69 genera, and 10 families, among which, Nymphalidae had the higher species number, individual's number, and diversity index than the other families. The butterflies in the study area were a mixture of Oriental and Palaearetic species, with the Oriental species diminished gradually and the Palaearetic components increased gradually with increasing altitude. Among the three vertical zones ( <800 m, 800-1200 m, and >1200 m in elevation), that of 800-1200 m had the most abundant species of butterflies; and among the six habitat types (deciduous broad-leaved forest, evergreen conifer forest, conifer-broad leaf mixed forest, bush and secondary forest, farmland, and residential area), bush and secondary forest had the higher species number, individual's number, and diversity index of butterflies, while farmland had the lowest diversity index. The similarity coefficient of butterfly species between the habitats was mainly dependent on vegetation type, i.e., the more the difference of vegetation type, the lesser the species similarity coefficient between the habitats, which was the highest (0.61) between conifer-broad leaf mixed forest and bush and secondary forest, and the lowest (0. 20) between evergreen conifer forest and bush and secondary forest.
采用定点、线路截获及随机调查的方法，于2005年至2008年对鹞落坪国家级自然保护区蝴蝶的垂直分布及群落多样性进行了调查。共采集到3681号标本，隶属于10科69属111种，其中蛱蝶科的种类数、个体数及多样性指数均高于其他科。研究区域内的蝴蝶为东洋界和古北界种类的混合，随着海拔升高，东洋界种类逐渐减少，古北界成分逐渐增加。在三个垂直带（海拔<800米、800 - 1200米、>1200米）中，800 - 1200米带蝴蝶种类最为丰富；在六种生境类型（落叶阔叶林、常绿针叶林、针阔混交林、灌丛及次生林、农田、居民区）中，灌丛及次生林蝴蝶的种类数、个体数及多样性指数较高，而农田的多样性指数最低。生境间蝴蝶种类的相似系数主要取决于植被类型，即植被类型差异越大，生境间的种类相似系数越小，针阔混交林与灌丛及次生林之间的相似系数最高（0.61），常绿针叶林与灌丛及次生林之间的相似系数最低（0.20）。
