兼顾景观效益的三汊河国家湿地重点水鸟生境与修复分析

Analysis on Habitat and Restoration of Key Waterbirds in Sancha River National Wetland Considering Landscape Benefits

找出三汊河国家湿地重点水鸟数量减少原因;方法:采用样带法、定点观察法和数量研究法,调查研究区域内鸟类种类、数量、分布和生境类型现状,与2014年-2015年调查结果进行比较。结果:三汊河湿地现在鸟类种数减少15种。结论:应该通过水文修复、开辟浅滩、设置人工鸟巢、植被恢复、增殖鱼类、螺类等水生动物等一系列措施进行生境修复,为周边水鸟提供安全舒适的栖息环境,吸引鸟类回归,保护湿地水鸟物种多样性。

Objective:To identify the reasons for the decrease in the number of key waterfowl in the Sancha River National Wetland.Method:Using transect method,fixed-point observation method,and quantitative research method,investigate the current situation of bird species,quantity,distribution,and habitat types in the study area,and compare them with the results of the 2014-2015 survey.Result:The number of bird species in the Sancha River wetland has decreased by 15.Conclusion:Through a series of measures such as hydrological restoration,shoal opening,artificial nest setting,vegetation restoration,proliferation of fish,snails and other aquatic animal,habitat restoration can provide a safe and comfortable habitat for surrounding waterfowl,attract birds to return,and protect species diversity of wetland waterfowl.
