Abstract: During the summer of 2001 and 2002, we studied three typical summering avian communities in twenty-seven habitats that belong to subtropical cultivated land,wetland and forestland habitats within the auburb area of Shanghai. 68 species,which belonged to 11 orders,25 families, were recorded in three habitats.The total average density of birds is 2.7237/hm² ,The Shannon-wiener index(H)is 2.2815, species evenness(J) is 0.5407, C index is 0.2254. In three typical habitats,the diversity index(3.0759) in wetland area is higher than others, but the density (0.8495) is lower than others.On the contrary, the diversity index (1.6464) in cultivated land is lower than others but the density (4.9608) is higher than others. Meanwhile, the species of forest birds is few comparatively.The results showed that that teh density will be rose up through improving naturalness of enviroment,increasing spatial heterogeneity and reducing the disturbance of human beings.
