摘　　要：2012—2013年选取原始阔叶红松林、人工林、天然次生林和灌丛草甸4种典型植被生境,对小兴安岭凉水自然保护区的蝶类进行了系统研究。共捕获蝶类1438头,分属7科47属76种,4种植被生境中蝶类群落优势类群均为蛱蝶科,不同生境蝶类群落相似性与生境植被类型密切相关。计算分析了4种植被生境中蝶类多样性指数、物种丰富度、优势度指数、均匀度指数和种-多度关系,结果表明:3种森林生境蝶类多样性大于灌丛草甸,原始阔叶红松林蝶类具有最高的多样性指数、较高的物种丰富度、均匀度指数以及最低的优势度指数,种-多度分布为对数正态分布,说明环境质量优越,最适合蝶类生存和繁衍;灌丛草甸蝶类的多样性指数、物种丰富度和均匀度指数均为最低,而优势度指数最高,种-多度分布为对数级数分布,反映植物群落结构较单一,适合各种蝶类生存和繁衍的资源不足;天然次生林蝶类多样性指数、物种丰富度高于人工林,均匀度小于人工林,但前者种-多度分布为对数级数模型,后者为对数正态模型,说明在封山育林状态下,对森林植被组成进行适当合理的干扰。Liangshui Nature Reserve lies in the eastern part of Dalidailing Mountain, a branch of the Xiao Xing＇ an Mountains in Heilongjiang province in the eastern part of northeast China. Characterized by low mountains and hills, the reserve is situated at the eastern edge of Eurasia. The typical temperate continental monsoon climate is characterized by long, cold, snowy winters and short, cool, rainy summers. The original broad-leaved Korean pine forest, the main forest type in the reserve, is well preserved here, with paleo-floristic and faunal elements and typical community phytogenesis. The reserve has a diversity of forest types. The butterfly species in Liangshui Nature Reserve were studied based on samples collected in four forest types： original broad-leaved Korean pine forest, plantation forest, natural secondary forest, and shrub meadow. In the survey, the net catching method was the main method to collect samples of insects, and samples were then identified in the laboratory. Seven butterfly families, 47 genera, and 76 species were identified from a total of 1438 specimens. The Nymphalidae was the dominant family in all four habitats. Analysis of similarity showed that the types of butterfly communities observed were closely related to the vegetation types. The diversity, specific richness, dominance, evenness indices, and species-abundance relationship within the four kinds of habitats were calculated and analyzed. The results showed that changes in environmental quality influenced the diversity of the butterfly communities, and butterflycommunity diversity indices were lowest in the shrub meadow habitat. The butterfly community of the original broad-leaved Korean pine forest had the highest diversity index; the species richness and evenness indices were relatively high in this community, while the dominance index was the lowest among the four kinds of habitats. Additionally, the species rank abundance fits a lognormal distribution; this type of model shows the environment in this area is of superior qual
