桂阳舂陵国家湿地公园鸟类资源调查

Investigation of bird resources in Guiyang Chongling National Wetland Park of Hunan Province

在湖南桂阳舂陵国家湿地公园,采用样线法对区内鸟类资源进行调查,共记录到鸟类104种,隶属于16目45科,其中留鸟50种,夏候鸟17种,冬候鸟34种,旅鸟3种;鸟类时空分布存在差异,表现为鸟类多样性指数上春季>秋季>冬季>夏季,春季物种多样性指数3.25最高,鸟类分布均匀性指数上湿地恢复区>洪泛平原区>库塘峡谷区>近岸农业生产区>原水产养殖区,其中湿地恢复区鸟类均匀度较高,原水产养殖区鸟类分布均匀度最低。鸟类是桂阳舂陵国家湿地公园的重要组成部分,可敏锐地反映公园环境质量的好坏,今后须加大区内鸟类资源保护和栖息地管理工作力度。

The method of line translocation was used to investigate the bird resources in Guiyang Chongling National Wetland Park of Hunan province.A total of 104 bird species were recorded,belonging to 45 families of 16 orders.Among them,50 were resident birds,17 were summer migrants and 34 were winter migrants.The results showed that the diversity index of birds was spring>autumn>winter>summer,and the highest was 3.25 in spring.The evenness index of bird distribution was wetland restoration area>flood plain area>reserviors and pond gorge area>coastal agricultural production area>original aquaculture area.The evenness of bird distribution was higher in wetland restoration area,and the evenness of bird distribution was lowest in original aquaculture area.Birds are an important part of Guiyang Chongling National Wetland Park,which can sensitively reflect the environmental quality of the park.It is necessary to strengthen the protection of bird resources and habitat management in the future.
