Abstract: In order to investigate the avifauna and bird community in Weihe Plain and to discuss the similarity between communities in the different habitats and its influ encing factors,the bird species and their abundance in seven different sites were studied by line sampling method,Shannon-Wiener,Pielou indices and Multivar iate analysis.According to the record,there are 63 species in that area,belonging to 13 orders,29 genera and 47 families.Dominant species in different suits showed that water area was the important factor to special bird.Diversity were related to human disturbance (Y=2.945-0.352X).Higher evenness suggested that different communities distributed even,and influenced by water and human disturbance.The results of the Hierarchical Cluster,Principal Components Analy sis (PCA) and Multidimensional Scaling (MDS) suggested that all suits could be divided into 3-4 groups by the human disturbance,and the result of the MDS was b etter than that of the Hierarchical Cluster.Special factor,such as human disturbance,had influenced the bird communitys structure significantly and resulted in dissimilarity between similar habitat.
