摘　　要：选择海南岛有红树林分布的地点和红树林完全消失的地点,于2003—2005年冬季进行越冬水鸟资源调查。结果表明:在有红树林分布的区域如后水湾和东寨港等地,由于底栖生物的密度较高,因此水鸟的种类、数量以及水鸟多样性都明显高于没有红树林分布的地点。鸭科、科和鹬科水鸟的数量和种数在两者之间并无显著差异,而鹭科鸟类的种数和数量以及鸥科鸟类的种数在两者之间存在着显著差异。一些体型中等的鹬类如红脚鹬、青脚鹬和泽鹬的数量明显多于没有红树林分布的地点。从判别分析的结果可以看出,鹭科鸟类的种数和总数量是判别两地点最重要的2个变量。An investigation on status of waterbirds in two sorts of plots respectively with mangrove-forested and mangrove- deforested in Hainan Island was conducted consecutively in winters from 2003 to 2005 to facilitate the conservation and management of mangrove forests in Hainan Island. The results showed that the waterbird species, numbers and diversity were much higher in mangrove forests wetlands than that of mangrove-deforested plots, probably due to a higher density of invertebrate animals on the mudflat of mangrove forests, which attracted the more waterbirds to feed on. Whereas there was no marked difference in the numbers of ducks, plovers and small shorebirds such as Rufous-necked Stint,Temminck＇ s Stint between the two habitats, the numbers of egrets and herons were significantly higher on mangrove forests wetlands, and the numbers of some middle and larger sandpipers, such as Common Redshank, Common Greenshan.k and Marsh Sandpiper, on mangrove forests wetlands were higher than that of mangrove-deforested plots. Finally, some conservation suggestions were put forward to strengthen the conservation and management of mangrove forests in Hainan Island.
