广州南沙红树林湿地鸟类群落多样性(2005～2010)

Bird Community Diversity of Nansha Mangrove Wetland in Guangzhou,China(2005～2010)

为探讨城市化对鸟类群落的影响,2005～2010年对广州南沙红树林湿地鸟类群落多样性进行了研究.结果表明:共记录鸟类149种,隶属于16目42科97属;其中冬候鸟或旅鸟77种,占51.7%,留鸟63种,占42.3%,夏候鸟9种,占6.0%;鸟类群落呈现出较强的季节性,从总体上看,物种数和总数量呈现秋冬季高峰,夏季最低.红树林湿地区具有最高的鸟类物种多样性与科属多样性,物种多样性和科属多样性变化趋势表现为红树林湿地区>河涌林带区>水域区.南沙红树林湿地的保护对丰富鸟类群落多样性具有重要作用.
