摘　　要：[目的]研究几何形态学方法在研究蝶类昆虫种内居群间分化的可行性和有效性。[方法]以冰清绢蝶为研究对象,对我国冰清绢蝶主要地理分布区的10个地理居群共200个体翅脉脉相的相关指标进行研究,利用三维数码显微镜共测量、分析前后翅共计17种脉相的几何形态学性状(包括翅脉长度、翅脉两点间线段长度、中室面积等),再利用SPSS 21.0软件对筛选出的有效性状进行了统计和聚类分析。[结果]冰清绢蝶10个地理居群的形态分化和它们的地理分布之间存在明显的相关性;安徽滁州琅琊山的居群在聚类树上的位置较为特殊,没能显示出与其地理分布间的明显关联性。[结论]几何形态学分析方法在蝶类的种内分化研究中是一种十分有效的辅助手段。[ Objective] The aim is to investigate the feasibility and validity of the method of geometric morphology in the study of the differentia-tion among populations of butterflies. [ Method ] With Pamassius glacialis as study object, related index of 200 individual venation in 10 geograph-ic populations in major geographic regions were studied. Geometric morphological characters （including length of the venation, length of the line between two venation,area of the discal cell,etc. ） of a total of 17 kinds of venation of forewings and hindwings were analyzed through three-di-mensional digital microscope, and then SPSS 21. 0 software was used to carry out statistical analysis and cluster analysis on the selected effective characters. [Result] There was a significant correlation between morphological differentiation and geographical distribution of the 10 geographic populations of the Pamassius glacialis;since the location of the cluster in the clustering tree on Langya Mountain in Chuzhou Anhui was special, thus there was not a clear correlation between the geographical distribution. [ Conclusion ] Method of geometric morphology analysis is a very ef-fective auxiliary means in the study of intraspecific differentiation of butterflies.
