摘　　要：该文将城市滨水绿道规划用于治理某市内河污染,并分析应用效果。针对目标城市内河的交叉型河网结构与城市自然概况,沿内河水流方向各规划出五条城市滨水绿道,通过围合形成绿道网与绿道环,制定出纵向排水、植被种植、绿道铺设、护坡铺设等具体绿道规划措施。采用不同测定方法,取得各监测点河流中氨氮、总氮、总磷等污染成分及溶解氧的质量浓度,利用内梅罗综合污染指数评价方法,明确各监测断面的内河水体污染级别。滨水绿道规划前后内河各成分质量浓度、水质类别、污染等级及水体情况的变化表明,滨水绿道能改善内河水环境质量,弱化富营养化状态,加强水体自然生态缓冲能力、自净能力与承载力,消除Ⅴ类水体,降低污染程度,保证生态环境均衡。In this paper,the urban waterfront greenway planning is used to control inland river pollution of a city,and the application effect is analyzed.In view of the intersecting river network structure of the inland river and the natural situation of the target city,five urban waterfront greenways are planned along the water flow direction of the inland river.The greenway network and greenway ring are formed by enclo-sing them,and the planning measures such as longitudinal drainage,vegetation planting,greenway lay-ing,slope protection laying and other specific greenway planning measures are formulated.The dfferent measurement methods are used to obtain the mass concentrations of ammonia nitrogen,total nitrogen,to-tal phosphorus and other pollutant components and dissolved oxygen in the rivers at each monitoring point.Using the Nemerow comprehensive pollution index evaluation method,the pollution level of the in-land water body of each monitoring section is clarified.The changes in the quality concentration of vari-ous components,water quality categories,pollution levels and water conditions in the inland river before and after the waterfront greenway planning verify that the waterfront greenway can improve the water envi-ronment quality of the inland river,weaken the eutrophication state,and strengthen the natural ecological buffer capacity self-purification capacity and bearing capacity of the water,eliminate class V water,re-duce the pollution levels,and ensure the balanced ecological environment.
