福建红树林湿地鸟类区系研究

红树林湿地是热带、亚热带海岸带的重要湿地类型。由于红树林是自然辅助供能的高生产率的生态系统 ,具有高光合率、高呼吸率和高归还率的三高特点 ,为红树林区底栖动物的生活提供了能量来源 ,丰富的底栖动物又为鸟类等高等动物提供了充足的饵料来源。红树林湿地特殊的环境特点 ,使之成为咸淡水交迭的环境下生存的动植物、微生物丰富的基因库10 ] 。因此 ,红树林区域在生物多样性研究中具有重要价值。在香港米埔红树林保护区 ,鸟类学家对当地鸟类的迁徙和生态进行了 30多年的研究15,16 ] ,2 0世纪 80年代后对广东、广西、海南等地主要红树…

Bird Communities in Four Mangrove Wetlands in Fujian

From January 1996 to January 1997, birds survey was carried out in 4 mangrove wetlands in Fujian. As a result, 92species, belonging to 55 genera, 27 families, and 13 orders were recorded. Among them， 29 species, 31.52 % of the total were passeriformes; 63 species, 68.48% of the total were nonpasseriformes. The survey revealed that the bird communities in Fujian mangrove wetlands had the features as follows: ①Nonpasseriformes was more than passeriformes. Wading birds were more abundant in bird communities. ②Farm birds were common and forest birds were scarce. ③Lack of endemic species. ④Winter visitors and passing migrants were dominant in bird communities. ⑤Migrant behaviors varied with species. ⑥Mangrove wetland is important for bird conservation, especially for egrets and migrant wadings.
