【摘要】 河流在人类的生产生活中发挥着重要的作用,但是随着城市发展规模的不断扩大,城市河流生态退化日趋严重,以河流为行洪、排污渠道的传统河道治理思想已经不能满足社会需求。本文根据我国城市河流治理中河道形态设计存在的问题,从河床形态多样化角度出发,归纳了近自然河流治理河道断面及平面形态设计基本原则,依据治理程度将现有城市河流分类, 设计不同的河道形态改造方案,丰富水流流态,通过首先营造自然的河流形态,逐步修复河流生态系统,迈出近自然河流治理的重要一步。更多还原

【Abstract】 Urbanization has profound effects on streams.Urban streams represent a special challenge to river restorers because they are often highly degraded and subject to multiple impacts.The past focus on using urban streams for drainage and flood control has left many in poor condition.This paper analy- zes the most severe problem on urban rivers and summarizes the basic principles to design the near na- ture river bed form.And according to the regulation degree,the urban rivers are classified and designed different restoration scheme.Following rebuilding nature river morphology,the degraded riverine eco- system will be restored.更多还原
