摘要
2005-2006年的1月、4月、7月和10月，利用样带法对广州市新垦红树林湿地和周边农田进行鸟类物种多样性研究。利用Shannon-Wiener指数分析了生境类型的鸟类群落种数、数量、物种多样性、均匀性指数等特征。结果表明，新垦红树林湿地1月鸟类种数高于周边农田湿地2倍，鸟类群落个体数量高于农田湿地9倍；红树林湿地4月和7月鸟类种数高于周边农田湿地1．5倍，鸟类群落个体数量高于农田湿地4倍；红树林湿地10月鸟类种数高于周边农田湿地1．5倍，鸟类群落个体数量高于农田湿地6．8倍；新垦红树林湿地和周边农田湿地鸟类物种多样性表现出明显的季节性变化。
From 2005 to 2006 in January, April, July and October, the bird diversity was investiaged in Xinken mangroves and fanning wetland with sample belt. The species and numbers of bird community, species diversity, and evenness indices were analyzed using the Shannon - Wiener index. The results shows that bird species was 2, 1.5, 1.5 times higher in mangroves than in fanning wetland in January, April and June, October, while the individual numbers of bird community are 9, 4, 6.8 times higher in mangroves than in fanning wetland in January, April and June and October.. It indicates that wetland of mangroves and farmland are significant for seasonal variation of bird species diversity.
