广西北部湾沿海地区水鸟多样性及季节变动

于2010年开始,对广西北部湾沿海地区水鸟多样性及其季节分布和变动情况进行调查研究。结果广西北部湾沿海地区共调查记录到水鸟151种,隶属于8目24科,其中国家重点保护鸟类有19种。本地区水鸟以冬候鸟比例最大,占51%。水鸟多样性的季节变动巨大,夏季主要是鹭科和秧鸡科鸟类为多,到冬季鹭科鸟类减少,鸻形目鸟类大幅度增加。水鸟的时间分布大致划分为迁徙期、繁殖期和越冬期,部分水鸟的繁殖、迁徙、越冬期有交叉重叠。

Diversity and Seasonal Variation of the Waterbirds in Beibu Gulf Coastal Area of Guangxi

From the beginning in 2010,the diversity and seasonal variation of the waterbirds in Beibu Gulf coastal area were investigated.In Beibu Gulf coastal area of Guangxi,151 waterbird species are recorded,which belong to 24 families and 8 orders,and 19 of them are national protected in China.In this area,the winter migrant has the largest rate of 51% among the 151 species.The diversity of waterbirds has great seasonal change,because the Heron and Rail are dominant in summer,but in winter the species and number of the Waders increase while the Heron reduce.The seasonal variation of the waterbirds is roughly divided to migration,breeding and wintering,which reveal overlaps in some waterbirds.
