长园河湿地生态修复工程实践

近年来,湿地恢复已成为当今社会生态恢复的重要课题之一,开展河道湿地生态修复是提高河道水环境承载能力、改善河道生态环境的有效途径.本文在长园河中下游段进行湿地生态修复工程实践,在全面分析长园河湿地现状的基础上提出生态修复目标,按照一定的修复原则把工程分为4个区域即湿地生态修复与景观优化示范区、河岸缓冲过滤带重建示范区、连通性修复与生态护岸示范区、生物浮岛示范区进行重点修复,修复后取得了很好的效果,为未来华北地区山区型河道退化湿地的生态修复提供示范作用.

ChangyuanRiver Wetland Ecological Restoration Engineering Practice

In recent years,wetland restoration has become an important issue in ecological remediation realm of today＇s society.The development of river wetlands ecological restoration is an effective way to increase the carrying capacity of the river water environment,and improve river ecology environment.In this paper,the ecological restoration engineering along the middle and lower segments of Changyuan River was done.On the basis of a comprehensive analysis of the Changyuan River wetland status,the ecological restoration objective was drawn up.The project is divided into four regions according to certain restoration principles,which are wetland ecological restorationand landscape optimization demonstrationarea,riparian buffers filter strip reconstruction demonstration area,connectivity recovery as well as ecological embankment demonstration aera and biological floting island demonstrtion area.The focused restoration on these four areas showed good results,which played an exemplary role in the future work of mountainous river degraded wetland ecological restoration in north China.
