摘要
白洋淀是雄安新区重要生态功能区,白洋淀入淀河道承载着防洪行洪、向淀区输水的重要任务及河流廊道生态防护功能。通过对南拒马河、界河-龙泉河-清水河、潴龙河、萍河、瀑河、小白河等6条入淀河道典型河段调查,结合高分二号遥感影像解译分析结果,分析了6条入淀河道的物理障碍因素、物理连通状况及河岸植被带情况。按照功能定位,将河岸带划分为五种类型,基于InVEST模型的污染物净化效果分析,提出了不同类型河岸植被宽度与结构建议,可为下一步开展河道整治规划与建设提供科学依据。
Baiyangdian is an important ecological functional area in Xiong'an New Area.The channels to Baiyangdian carries important tasks of controlling flood,transfering water and protecting ecologies of the rives around it.Based on the investigation of six rivers entering the lake,such as the Nanjuma River,the Jiehe River-the Longquan River-the Qingshui River,the Zhulong River,the Pinghe River,the Puhe River and the Xiaobai River,which are typical river branches in this area,and combined with the interpretation and analysis results of the Gaofen-2 remote sensing images,analyzed the physical obstacles and physical connectivity of the six riversand the riparian vegetation belts of the six rivers,which can be divided into five types according to their functional orientation.Based on the analysis of pollution interception effect of InVEST model,then gives width and structure suggestions of different types of riparian vegetation.Research can provide a basis for scientific and rational river regulation planning and construction in the later period.
