Abstract:

In order to determine butterfly resources and diversity status of the Qinling National Botanical Garden, we used the transect method across three years to observe butterflies within five habitats. A total of 134 species were recorded, belonging to 5 families and 76 genera. The species richness index, diversity index, evenness index and dominance index were 1.3295, 3.4616, 0.7068 and 0.7656, respectively, among them, Nymphalidae had the largest number of genera (33) and species (65), while Papilionidae had only 5 genera and 10 species. Nymphalidae had the highest diversity index (2.8525) and richness index (1.3622). Papilionidae had the lowest diversity index (1.4936) and Pieridae had the lowest richness index (0.2790). The comparison of butterfly diversity indicators in different habitats showed that butterfly diversity index increased with the increase of vegetation richness. These results show an abundance of butterfly diversity, indicating that Qinling National Botanical Garden may be of significant conservation value.
