From May 2004 to February 2005, an investigation was made on the avian communities in four typical habitats, i.e., village and farmland, urban woodlot, floodplain, and riverine wetland in Wuhu City, with the related diversity indices analyzed. A total of 117 species belonging to 15 orders and 31 families was recorded. The avian species and G-F index in village and farmland, urban woodlot, and floodplain were higher in summer than in winter, while the species number, Shannon-Wiener index and Pielou index in riverine wetland were significantly higher in winter than in summer. The avian species and G-F index in urban woodlot were the highest, and the Shannon-Wiener index and Pielou index in floodplain were higher than those in other three habitats. The highest density was observed in village and farmland in summer and in urban woodlot in winter, being 31.1140 and 42.9160 ind x hm(-2), respectively. The avian species, density, Shannon-Wiener index and G-F index in riverine wetland were the lowest. Avian diversity could be enhanced by increasing spatial heterogeneity and reducing human disturbance.
2004年5月至2005年2月，对芜湖市的四种典型栖息地，即村庄与农田、城市林地、河漫滩和河流湿地的鸟类群落进行了调查，并分析了相关多样性指数。共记录到15目31科117种鸟类。村庄与农田、城市林地和河漫滩的鸟类物种数和G-F指数夏季高于冬季，而河流湿地的物种数、香农-威纳指数和皮洛指数冬季显著高于夏季。城市林地的鸟类物种数和G-F指数最高，河漫滩的香农-威纳指数和皮洛指数高于其他三种栖息地。夏季村庄与农田的鸟类密度最高，冬季城市林地的鸟类密度最高，分别为31.1140和42.9160只·hm(-2)。河流湿地的鸟类物种数、密度、香农-威纳指数和G-F指数最低。增加空间异质性和减少人为干扰可提高鸟类多样性。
