【摘要】 为了解河南南太行山区的蝴蝶的群落组成和分布特点，本研究于2020-2021年对该地区不同生境的蝴蝶群落进行了系统调查和多样性分析。结果共记录到蝴蝶2 688头，隶属于5科55属79种。蛱蝶科的种类数(44种)和个体数(1 329头)均为最多，是保护区的优势类群。玉斑凤蝶Papilio helenus是该地区首次记录的新种。不同生境间物种数和Margalef丰富度指数有明显差异(P<0.05),天然林中蝴蝶的物种数、个体数、Shannon多样性指数、Margalef丰富度指数和Pielou均匀度指数均最高。不同生境间蝶类的相似性有所差异，天然林和次生林的Jaccard相似性系数最大，为0.6849,天然林和农田的Jaccard相似性系数最低，为0.3971。区系组成主要以广布种(59.49%)为主，古北种(30.38%)次之。蝴蝶资源的多样性和丰富性受不同生境的植被类型和人为干扰程度的影响。更多还原

【Abstract】 In order to understand the community composition and distribution characteristics of butterflies in the southern Taihang Mountains of Henan, systematic survey and diversity analysis were used to analyse butterfly communities in different habitats in the region from 2020 to 2021. A total of 2 688 butterflies belonging to 55 genera and 79 species belonging to 5 families were recorded. The number of species(44 species) and the number of individuals(1 329) of Nymphalidae were the largest, which was the dominant group in the protected area. Papilio helenus was the first new species recorded in the area. There were significant differences in the number of species and richness index between habitats(P<0.05), and the number of species, individuals, Shannon diversity index, Margalef richness index and Pielou evenness index of butterflies in natural forest were the highest. The similarity of butterflies varies between habitats, with the largest Jaccard similarity coefficient of 0.6849 in natural forest and secondary forest, and the lowest Jaccard similarity coefficient in natural forest and farmland at 0.3971. The fauna wa s mainly composed of Widespread species(59.49%), followed by Palaearctic species(30.38%). The diversity and richness of butterfly resources were influenced by vegetation types and the degree of anthropogenic disturbance in different habitats.更多还原
