大兴安岭塔源林场不同生境蝶类多样性与相似度分析

Analysis of Butterfly Diversity and Similarity in Different Habitats of Greater Khingan Range Tayuan Forest Farm

[目的]对大兴安岭塔源林场不同生境蝶类的多样性与相似度进行分析。[方法]首次对大兴安岭塔源林场蝶类资源进行调查,掌握塔源林场不同生境中蝶类的资源分布情况。[结果]经研究发现塔源林场有蝶类82种活动,隶属于7科53属,包括优势种11种。通过分析样地中野生蝶类资源的分布情况发现,灌丛环境蝶类多样性与优势度指数最高,草甸的均匀度指数最高,湿地的各项指数均最低。相似度情况以灌丛和湿地最高,林缘和草甸的相似度最低。[结论]该研究对于分析大兴安岭塔源林场蝶类情况具有重要的意义。

[Objective] To analyze the butterfly diversity and similarity in different habitats of Greater Khingan Mountains Tayuan Forest Farm. [Method] To investigate the butterfly resources and master the distribution of butterfly in different habitats in the Greater Khingan Mountains Tayuan Forest Farm. [Result] There were 82 species of butterfly in the Tayuan Forest Farm, belonging to 53 genera of 7 families, of which 11 were dominant species. By analyzing the distribution of wild butterfy resources in the plots, we found that butterfly diversity and dominance index were the highest in shrub environment, and the evenness index of meadow was the highest, and the index of wetland was the lowest. The similarity was the highest between shrub and wetland, and the similarity between forest edge and meadow was the lowest. [Conclusion] This study is of great significance for the analysis of butterfly in Greater Khingan Mountains Tayuan Forest Farm.
