This paper studied the structure of [WT5,5”BZ]butterfly communities and species diversity and [WT5,5”BZ]distribution character.The way of especial spot collection and net-catch in route were used in the investigation in middle re-gion of Qilian Mountain of Qinghai province.The result showed:The total number of butterflies collected was 2.500 which consist of 6 families,35 genera and 53 species. This paper classifies butterflies into 5 communities as follows: 1)the community of field of hill near 23 species,accounts for 43.4% of the total number; 2)the community of mountain and grassland 13 species,accounts for 24.5% of the total number; 3)the community of forest and grassland 13 species,accounts for 24.5% of the total number; 4)the community of alpine shrub meadow 22 species,accounts for 41.5%of the total number; 5)the community of bareness rock 6 species,accounts for 11.3% of the total number. The number of species in the community of field of hill near and alpine shrub meadow were the hightest, the number of species in the community of bareness rock was the fewest.
