Avian Diversity in Different Habitats at Huaping Nature Reserve during Summer

July to August in 2005, we studied the Avian community structure in summer with transect lines methods in Huaping National Nature Reserve.According to the Shannon-wiener index,Pielou index,Dominance index and G-F index,we analyzed the avian diversity.Total of 66 species of birds belongs to 7 orders and 29 families were recorded.The number of species,species diversity and G-F index in the primary forest are the highest.The birds in that community has more species,families and genus,but the number is less.The avian density is the highest in the secondary forest,but the number aggregates several dominant species, diversity index is low.Farmland-economic forest has highest Pielou index,and the avian community structure will be reasonable,uniform and diverse.It is important for avian diversity,survival and multiplicity to protect spatial structure and distribution patterns,and to improve the complexity of plant community in various types of habitat.
