Avian Community Investigation and Diversity in Heilongjiang Dazhanhe Nature Reserve

Line transects and netting sampling methods were used to investigate avian resources in Dazhanhe Nature Reserve. Species diversity,evenness and the comparability index between different habitat communities were calculated. There were 203 avian species in Dazhanhe Nature Reserve,of which 92 Asseriformes species and 110 non-Asseriformes species were found,and composed mainly of Muscicapidae,Anatidae and Scolopacidae. Birds of the Palaearctic realm represented a higher proportion(65.52%) of avian species in Dazhanhe nature reserve,common species were less(30.54%) and little from Oriental realm(3.94%) were represented. For species diversity index of the four communities,the rank was wetlandforestscroplandresidents,the evenness index was ranked by wetlandforestscroplandresidents;the comparability index was ranked by residents-cropland(S=0.25) wetland-forests(S=0.23) wetland-cropland(S=0.14) residents-forests(S=0.07) .
