广东连南瑶排梯田国家湿地公园鸟类物种多样性

Avian species diversity in Yaopai Terrace National Wetland Park of Liannan,Guangdong Province

为掌握广东连南瑶排梯田国家湿地公园的鸟类物种多样性,2019年10月至2020年10月,采用样线法和样点法对湿地公园鸟类进行了系统调查。结果显示,共记录到鸟类89种,隶属于12目38科。在89种鸟中,有留鸟62种,夏候鸟10种,冬候鸟14种,旅鸟3种;鸟类区系为,古北界26种,东洋界55种,广布种8种;另有13种鸟类属国家二级重点保护野生动物。在7种生境中,灌丛、乔木林、农田中鸟类物种多样性指数较高,沼泽、库塘、村落、河流中鸟类物种多样性指数较低。最终,建议湿地公园管理部门通过加强湿地修复、降低人为干扰、秋冬季维持梯田湿地环境等措施提高湿地鸟类的物种多样性。

In order to master the bird species diversity in Guangdong Liannan Yaopai Terrace National Wetland Park,a systematic survey program was implemented with the sample line method and sample point method in the wetland park from October 2019 to October 2020.The results showed that a total of 89 species of birds belonging to 12 orders and 38 families were recorded.Among the 89 species,there were 62 species of resident birds,10 species of summer migratory binis,14 species of winter migratory birds and 3 species of traveling birds;in tenns of fauna composition,there were 26 species in the Palearctic Region,55 species in the Eastern Oceanic Region,and 8 species in the Widespread Region;in addition,13 species belonging to the national secondary key protected wildlife.Among the seven habitats,the bird species diversity index in shrubs,arbor forests and fannland is high,while that in swamps,reservoirs,ponds,villages and rivers is low.Finally,it is suggested that the wetland park management department must improve species diversity of wetland birds by strengthening wedand restoration,reducing human interference,and maintaining terrace wetland environment during autumn and winter.
