Abstract:A survey on birds was conducted in the Three Gorges Reservoir of Chongqing area from 1996 to 1997. During the two-year survey, 18 929 individuals of birds, belonging to 226 species, 48 families and 15 orders, were recorded. Components and species diversity of the five bird communities were analyzed by Number rank, Sorensen Similarity index, Shannon-Wiener index and Pielou index. The results suggest that 1) The species components of the bird communities in the natural forests, in the manual forests, in the shrubland and in the aquatic communities are similar to that in the cropland; 2) The bird communities in the natural forests are the greatest in diversity; 3) Because of frequently anthropological disturbance, bird communities in the reservoir are mainly composed of Passeriformes birds.
