于2016至2018年间，采用样线法调查了九万山国家级自然保护区内的蝴蝶种类，分析了其蝴蝶群落的组成和多样性特征。结果表明，调查共记录蝴蝶6 965头，分属5科96属169种。其中，蛱蝶科Nymphalidae的属数、种数和个体数最多，分别为39属、85种、3 544头；粉蝶科Pieridae的物种数最少，仅为15种；弄蝶科Hesperiidae个体数最少，仅有416头。126种蝴蝶的个体数占比低于1%，属于稀有类群。常绿阔叶林带的多样性指数最高，而灌丛区和大型湖泊区间的相似性系数最高（0.56）。随海拔升高，蝴蝶物种数、优势度指数和丰富度指数呈现出先减后增的趋势，而多样性指数和均匀度指数则表现出先增后减的趋势。九万山国家级自然保护区内蝴蝶物种丰富，但稀有类群占比高，且蝴蝶个体数呈现出一定的下降趋势，提示该区域蝴蝶群落多样性面临威胁。因此，建议加强该地区蝴蝶资源特别是针对稀有类群的监测与保护，以维护其生物多样性。

英文摘要:

From 2016 to 2018, the transect method was employed to survey butterfly species in Jiuwan Mountain National Nature Reserve, analyzing the composition and diversity characteristics of butterfly communities. Results revealed a total of 6,965 butterfly individuals, comprising 5 families, 96 genera, and 169 species. Among these, Nymphalidae had the highest number of genera (39), species (85), and individuals (3544); Pieridae had the fewest species (15), and Hesperiidae had the fewest individuals (416). The individual counts of 126 butterfly species accounted for less than 1% of the total, classifying them as rare taxa. The evergreen broad-leaved forest zone exhibited the highest diversity index, while the shrubland and large lake zone showed the highest similarity coefficient (0.56). With increasing elevation, butterfly species, dominance index, and richness index demonstrated a pattern of initial decrease followed by increase, while diversity and evenness indices showed an initial increase followed by decrease. Although Jiuwan Mountain National Nature Reserve supports rich butterfly diversity, the high proportion of rare taxa and the apparent declining trend in butterfly abundance suggest that butterfly community diversity in this region faces threats.. Therefore, strengthening monitoring and conservation efforts for butterfly resources, particularly for rare taxa, is recommended to maintain biodiversity in this area.
