于1997~1999年对青海祁连地区不同生境类型中蝴蝶多样性进行了研究。研究中依据海拔高度、气候、土壤和植被的不同将该地区的蝴蝶生境划分为5种类型:山缘农田、山地草原、 森林草原、高寒灌丛草甸、裸岩。共收集蝴蝶4367只,隶属于6科35属53种。计算了5种生境 类型中蝶类物种丰富度、相似性系数、多样性指数。其中,蝶类物种丰富度由小到大的顺序为:裸岩(6种)<山地草原(13种)<森林草原(14种)<高寒灌丛草甸(22种)<山缘农田 (23种);多样性指数依次增加的顺序为:裸岩(H′=1.4629)、森林草原(H′=2.2398 )、山地草原(H′=2.2676)、山缘农田(H′=2.7071)、高寒灌丛草甸(H′=2.7734) ;森林草原和山缘农田的相似性系数最高(0.3704),其次为山地草原和高寒灌丛草甸(0.2500),裸岩与其他生境类型的相似性系数最低。

The faunal composition of butterflies in different habitat types in the Qilian area of Qinghai Province , northwest China , was surveyed f rom 1997 to 1999. Five habitat types were classified based on altitude , climate , soil and vegetation differences : hilly cultivated land , mountain steppe , forest steppe , alpine shrub meadow and bare rock. Of the total collection of 4 ,367 specimens , 53 species of 35 genera in six families were identified. Species richness , species composition similarity (J accard index) and species diversity index ( Shannon-Wiener index , H′) were calculated for the five habitat types. The species richness increased in the following sequence : bare rock (6 spp. ) , mountain steppe (13 spp. ) , forest steppe (14 spp. ) , alpine shrub meadow (22 spp. ) and hilly cultivated land (23 spp. ) . In cont rast , the species diversity increased in a different sequence : bare rock ( H′= 1.4629) , forest steppe ( H′= 2.2398) , mountain steppe ( H′= 2.2676) , hilly cultivated land ( H′= 2.7071) and alpine shrub meadow ( H′= 2.7734) . The butterfly species composition between forest steppe and hilly cultivated land had the highest similarity (J accard index = 0.3704) , with the second highest similarity between mountain steppe and alpine shrub meadow (J accard index = 0.2500) , and the lowest similarity between bare rock and other habitat types.
