摘要
根据植被、地貌和蝶类生活习性,将蝶类的生境划分为11个类型,5个垂直分布带.结果表明：已知研究区内分布有蝶类274种,隶属于10科123属.罕见种86种,优势种10种,共占蝶类总数的35%.其中,绢粉蝶属种类占中国绢粉蝶的52.6%,占调查区优势种的30%.阔叶林和各种类型灌丛最适宜蝶类栖息,植被最好的1 500~2 000 m垂直带的蝶类种类最多,个体数最高.
This paper reports the ecogeographical distribution of butterflies in the Daxiangling Mountains in Sichuan province, which is a part of the results of a systematic survey of butterflies in the Hengduan Mountains carried out in May -- September of 2006. In the survey, the habitats of butterflies were divided into 11 types and 5 vertical zones according to the vegetation, landforms and the life habits of butterflies. A total of 274 species of butterfly, belonging to 123 genera and 10 families, were recorded in the area studied. Of the 274 species, 86 were rare species and 10 were dominant species, which make up 35 percent of the total. Three species of Aporia accounted for 30 percent of Chinese Aporia and 52.6 percent of the dominant species in this area. They were found to distribute primarily in broadleaf forests and shrub vegetations at an elevation of 1 500--2 000 m, and such environments were favorable for the survival of the butterflies in the Daxiangling Mountains.
