Abstract: The scope of the fauna and geographical vertical distribution of the butterflies of the south slope of Qinling Mountains are studied. The investigators try to illustrate the conservation value of the Giant Pandas' habitat through the study which spans 8 years. 191 species are recorded, 3 of them are China's new records, and 44 of them are new records of Shanxi Province. The result of a serious of analysises shows that the percentages of Oriental species, Palearctic species and widely distributive species are 40.8%, 20.9% and 31.9% respectively. The fauna of butterflies of the south slope has the character of intergradation which is correlated to the geographic location of the Qinling Mountains. The obstruction of Qinling to Oriental species is more obvious to Palearctic species. The area in question has great conservation value as following aspects: (1) The population of butterfly shows great species abundance; (2) The heterogeneity of habitat revealed by the presence of multi-subspecies and multi-morphological species provides animals a steady habitat; (3) The faunal character and vertical distribution of butterflies show great value of ecological study; (4) The mid-mountain (800～2600m) that has better environmental condition and less human disturbance is a typical shelter for the wild animals.
