| 摘 要： | 结合自然地理与植被条件对山西蝶类多样性分布的现状进行研究，结果表明，其特点是：不同林区差异性大，呈南北递减趋势，受小气候环境影响较大，资源呈片段化分布，耕作区种类多样性丧失严重。根据已知的216种蝶类在山西15个林区的分布情况，采用聚类平均法(UPGMA)对这15个林区的蝶类多样性进行聚类分析，在相似性系数为0.85时，可将山西林区划分为5个蝶类分布地带。按照地理位置和自然景观的不同，分别称之为：Ⅰ.南端山地蝴蝶区；Ⅱ.南部盆地蝴蝶区；Ⅲ.中南部山地丘陵蝴蝶区；Ⅳ.中部高山蝴蝶区；Ⅴ.西北部丘陵蝴蝶区。在关键区系分析中，得知南端山地蝴蝶区和中部高山蝴蝶区是山西蝶类多样性分布的重要地区，对这两个区系加以保护，即可保护山西已知蝴蝶种类的97.7%。

| Abstract: | On the basis of natural geography and vegetation, the present situatio n of butterfly diversity was studied in Shanxi. The results indicated that: in different forest regions, the diversity of butterfly had much difference and decreased progressively from south to north. Meanwhile, influenced by the microclimate environment, the butterfly resources appeared clumpy distribution. In cultivation area, the diversity of species lost seriously. Based on the distribution of 216 species of butterflies in 15 forest regions, the diversity of butterfly species was studied by UPGMA clustering analysis. The result show that 15 forest regions were divided into 5 butterfly regions when the similarity coefficient was 0.85. They were: Ⅰ. South-end mountain butterfly region； Ⅱ. South part basin butterfly region； Ⅲ.Middle-South part mountain- hill butterfly region； Ⅳ. Middle part high mountain butterfly region；Ⅴ. Northwest part hill butterfly region. According to the result of key fauna analysis, the important butterfly regions in Shanxi were Ⅰand Ⅳ. It was inferred that 97.7% butterfly species in Shanxi could be preserved when butterflies in the two butterfly regions were protected. |
