The Study on Bird Community Diversity along the Xiamen Coastal Wetland in Summer

The bird species and their population abundance were investigated in 11 sampled areas along Xiamen coastline during summer(from June 1999 to August 1999).The results showed that there were 11 families and 27 species of birds found in Xiamen wetlands during the research period.The dominant species in population size were Little Egret(Egretta garzetta) and Kentish Plover(Charadrius alexandrinua),which reflect that many birds have lefted Xiamen coastline,and the individual number of there 2 species occupied 70.33% of the total individual number.Little Egret was the commonest bird,which distributed in every quadrat of the area.The diversity index of the bird community was higher in the reservoir of xiangshan(3.18) and Yundang Lake(2.33),and lower in Liushan(0).The diversity index of the bird community was mainly influenced by the amount of bird species and by the evenness of population number among the species.
