上海世界博览会园区内及周边地区鸟类多样性及其影响因子

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

2006年3-9月,对上海世博园区及周边地区鸟类资源进行普查,并对鸟类数量、种类和环境因子相关性进行研究。结果表明,该区域内现有鸟类10目27科67种,其群落多样性指数为3.46。运用概率统计方法分析了鸟类群落结构和分布特征,并将鸟类群落指数与园林绿地的8项环境指标进行分析,表明鸟类的种数、数量以及多样性指数与公园的面积、水域面积、形状指数、生境种类呈极显著相关;鸟类多样性、均匀性指数与树种总数呈显著相关;鸟类种数与环境中的位置条件有关。同时,就世博园区绿地建设中的引鸟工程,提出了5点建议。

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.
