摘　　要：1992-2002年6-9月,对祁连山北坡及河西走廊蝶类经行系统的采集,共采集蝶类标本6000余号,经鉴定、整理隶属于8科74属128种,根据世界及中国昆虫地理区划,该区分布有古北区系种99种,东洋区系种2种,广布种27种,以古北种占有绝对优势.同时对国内其他地区(包括其周边地区)的蝶类区系与祁连山及河西走廊蝶类区系作了相似度比较,初步探讨了祁连山北坡及河两走廊蝶类在中国蝶类区系中的地位,以及祁连山及河西走廊对于蝴蝶分布的影响和中国昆虫地理区划中的意义.The faunal composition of butterflies in the northern slope of the Qilian Mountains and in the Hexi Corridor were surveyed from 1992 to 2002. Of the total collection of more than 6000 specimens, 128 species of 74 genera in 8 families were identified. According to a preliminary analysis of our materials, it was estimated that 99 species belonged to the palaearctic realm, making up 77.35% of our collection; 2 species belonged to the Oriental realm, amounting to 1.56% of the total and other 27 species were cosmopolitan. Through a comparison of the similarity between the fauna and the peripheral region, the effect of the Qilian Mountains and the Hexi Corridor on the geographical insect regionalization in China was illustrated.
