Abstract:

We collected data on breeding birds in Anhui Province, and predicted and mapped their ranges using GIS techniques. We divided the study area into 425 grids which were used as operative geographic units to analyze breeding bird distributional patterns and hotspot. Faunistic composition analysis showed that geographic units in Anhui Province could be divided into two groups along a boundary from northern Dabie Mountain to Chaohu Lake. Indomalayan species accounted for 60% of the total species in all geographic unit groups, with an increase in the group’s prevalence from north to south. Ecological distribution analysis showed that bird distribution units could be divided into two groups which were consistent with division by climatic zones. When divided into seven groups, clusters were closely related to the environmental features such as terrain and landform. The hotspot analysis showed that richness of total breeding birds, breeding birds in the “List of Wildlife Under Special State Protection” of China, and breeding birds listed in CITES appendices I and II were all higher in southern Anhui Province. Therefore, we suggest that areas in southern Anhui Province should be targeted for special protection for bird diversity conservation.

Key words: species range type, species richness pattern, cluster analysis, distribution prediction, hotspot analysis
