北京野鸭湖湿地恢复工程的生物多样性效应研究

Study on The Effects of Biodiversity in Restoration Project of Yeyahu Wetland in Beijing

近年来由于人类活动和自然因素的影响,野鸭湖湿地退化严重.于2008～2010年调查了野鸭湖湿地恢复区恢复前后的植物、鸟类情况,对3年的野外调查数据进行分析,结果显示,自2009年春季实施的恢复工程,使恢复区湿地水域面积明显扩大;湿地植物种类、数量、盖度逐年增加;鸟类多样性指数较恢复前有大幅度提高,湿地水鸟所占比重逐年上升;同时,形成的独特景观带动了当地旅游发展.结果表明,该恢复工程较为成功,对野鸭湖湿地生态功能的恢复和改善具有指导作用,并可推广到其他类型湿地.

Influenced by the human activities and the natural factors,partial wetlands ecosystem has been deteriorating in the past.A survey including the condition of plants and birds in the restored area is made from 2008 to 2010 in Yeyahu Wetland Nature Reserve,the results show that after implementing restoration project since the spring of 2009,water area has increased,the species,quantity and the coverage of hygrophytes have increased year by year,as same as the waterbirds,the diversity index of birds is obviously improved than 2008,and the unique landscape brings some tourism benefits at the same time.It is indicated that this restoration project is relatively successful,it can be an instructional example for the restoration in Yeyahu and other wetlands.
