Avian diversity and its affecting factors in Shanghai Expo's site and surrounding areas

From March to September of 2006, an ornithological research in Shanghai Expo's site and its surrounding areas was conducted, and the correlations of the avian species and number with environmental factors were investigated. A total of 10 orders, 27 families and 67 species of birds were recorded, and the avian diversity index was 3.46. The statistic analysis on the structure and distribution of the avian communities, avian diversity indices and 8 major environmental factors showed that the avian species, number, and diversity were significantly correlated with the park area, water area and habitat style, the avian diversity and evenness indices were positively correlated with the number of tree species, and the location condition also had effects on avian species. Based on the results obtained, five advices for attracting avian in the greenbelt construction of Shanghai Expo were put forward.
