摘　　要：基于野外调查和标本信息的研究表明,苍山洱海国家级自然保护区有蝴蝶10科113属199种(亚种),包括云南省新记录8种;东洋区系成分占优势,达63.8%,广布成分占33.0%,古北成分占4.8%;主要存在3种来源:印中亚界起源、印度或印马亚界起源及古北界起源;蝴蝶垂直分布格局表现为物种丰富度随海拔升高呈现出先增加后降低的单峰分布格局;利用聚类分析划分出4个生态地理昆虫带:1)干热河谷灌木丛草坡昆虫带(1400～1700m);2)山地亚热带常绿阔叶林昆虫带(1800～2 300m);3)中山温性针阔混交林昆虫带(2 400～2900m);4)亚高山寒温性暗针叶林昆虫带(3 000～3 400m)。Based on the data from field investigation and the results of identifying butterflies specimens from Cangshan Erhai National Nature Reserve, 10 families, 113 genera, 199 butterflies species （subspecies）, including 8 new record species to Yunnan are recorded. The result of the faunistic characters shows that the Oriental species is dominant and accounts for 63.8%, the Cosmopolite species accounts for 33.0% and the Palaearctic species, 4.8%. After studying the fauna origin of these butterflies, the preliminary result shows that they mainly occured from the Indo-China subrealm, Indiardlndo-Malaysia subrealm and Palaearctic realm. The analysis of the spatial distribution pattern reveals that the species richness gradually increased and then decreased with the increase of elevation, such that a single-peak curve appears in vertical distribution. The result of cluster analysis indicates 4 eco-geographical insect phases： 1） the belt of slopes with bushes and grasses in dry and hot valleys （altitude 1 400-1 700 m）; 2） the belt of subtropical evergreen broad leaf forests on uplands （altitude 1 800-2 300 m）; 3） The belt of temperate zone mixed broad leaf and needle leaf forests on medium mountain heights （altitude 2 400-2 900 m）; 4） The belt of frigid-temperate zone dark needle leaf forests on sub-high mountain heights （altitude 3 000-3 400 m）.
