湿地是鸟类的重要栖息地。然而，由于全球人类活动，湿地正在加速退化，依赖湿地的鸟类物种比例不成比例地下降。通过对广东海丰湿地3个不同区域（拱坪、东莞连安围和大湖）鸟类群落的样线调查，评价了该湿地对鸟类的保护价值。共记录鸟类139种，其中国家重点保护鸟类26种。大湖的物种丰富度和多样性最高，而东莞连安围的鸟类丰富度最高，物种多样性最低。最后，公平的物种丰富度和丰度都最低。各区组成物种的特有性不同，鸟类群落具有互补性。物种丰富度和个体数存在明显的季节差异。春季物种丰富度和多样性最高。海丰湿地对水鸟和陆栖鸟类都具有很高的保护价值。我们的研究结果表明，海丰湿地和其他湿地的保护工作不仅应该关注越冬候鸟，而且应该关注留鸟。要达到有效的保护，我们应该把保护区和周围的湿地作为一个整体来考虑，把生态研究、教育和当地的经济发展结合起来。
Wetlands are critical habitats for birds. However, wetlands are being degraded at an accelerating rate due to global human activity, and a disproportionate fraction of wetland-dependent bird species are in decline. We evaluated the conservation value of a new Ramsar site, Guangdong Haifeng Wetlands, China, for birds, by comparing bird communities (using line transect data) in 3 different districts: Gongping, Dongguan Lian'anwei and Dahu. We recorded 139 species of birds, including 26 species that are protected at a national level. Dahu had the highest species richness and diversity, whereas Dongguan Lian'anwei had the highest abundance of birds and the lowest species diversity. Finally, Gongping had both the lowest species richness and the lowest abundance. The endemism of constituent species differed among districts, and the bird communities were complementary. There were significant seasonal differences in the species richness and the number of individuals. Spring had the highest species richness and diversity. The present study identifies the high conservation value of Haifeng Wetlands for both waterbirds and terrestrial birds. Our findings suggest that conservation efforts in Haifeng Wetlands and other wetlands should focus not only on wintering migratory birds, but also on resident birds. To accomplish effective conservation, we should consider the reserve and surrounding wetlands as a whole, incorporating ecological research, education and local economic development.
