摘要: 2006年对横断山区蝶类的垂直分布进行了调查,共发现蝴蝶603种,隶属12科229属,其中,蛱蝶科在属数、种类数和个体数量上均为最多,绢蝶科、珍蝶科和喙蝶科种类数量很少,但都是该区域的珍稀蝶类。从山麓到山地上部,沿高程梯度,蝴蝶群落的差异明显,无论是种类组成还是群落多样性特征,蝴蝶群落都呈现出明显的垂直分带;横断山区蝴蝶群落垂直带谱包括低山农田蝴蝶群落(Ⅰ)、山地中亚热带常绿阔叶林蝴蝶群落(Ⅱ)、山地暖温带常绿阔叶与落叶阔叶混交林蝴蝶群落(Ⅲ)、山地温带针阔混交林蝴蝶群落(Ⅳ)、山地寒温带暗针叶林蝴蝶群落(Ⅴ)和高山亚寒带灌丛草甸蝴蝶群落(Ⅵ),群落多样性指数变化趋势为Ⅱ>Ⅰ>Ⅲ>Ⅳ>Ⅴ>Ⅵ;在6个垂直带中,山地中亚热带常绿阔叶林带是地形最复杂、植物种类最丰富的垂直带,其蝶类物种数、个体数量、多样性指数均高于其他垂直带,表明在横断山区的蝴蝶群落垂直带谱中,该带蕴藏了最为丰富的蝶类多样性,因此也是最需要优先保护的生态带。

Abstract: An investigation was conducted along an elevation gradient with 26 sampling sections in Hengduan Mountains to study the vertical distribution of butterflies in the Mountains. A total of 603 species belonging to 299 genera and 12 families were recorded, among which, Nymphal had the most richness and abundance, while Parnassiidae, Acraeidae, and Libytheidae had the least ones but were rare and precious. Along the elevation gradient, there was an obvious difference in the species composition and community diversity, manifesting a distinct vertical pattern. The vertical distribution of the butterfly communities could be divided into six zones, i.e., low montane farmland zone (Ⅰ), mantane subtropical evergreen broadleaf forest zone (Ⅱ), montane warm temperate evergreen and deciduous broadleaf mixed forest zone (Ⅲ), montane temperate coniferous and broadleaf mixed forest zone (Ⅳ), montane cold temperate dark coniferous forest zone (Ⅴ), and alpine subfrigid shrub meadow zone (VI). The diversity index ranked in the order of Ⅱ>Ⅰ>Ⅲ>Ⅳ>Ⅴ>Ⅵ. Among the six zones, zone Ⅱ had the most abun
dant vegetation types and the most complex topography, and had higher specie richness, individual number, and diversity index of butterfly than the other zones,being the most important ecological area needed to be protected in priority.
