城市河道环境治理与生态修复研究——以温州市温瑞塘河为例
Study on Urban River Environmental Governance and Ecological Restoration—Taking Wenruitang River in Wenzhou City as an Example

“绿水青山就是金山银山”，生态与环境是可持续发展道路上不可或缺的方面。在城市文明时代，城市河道的环境状况是城市环境情况的一个重要缩影。河道在防洪排涝、灌溉、水上运输、游玩娱乐等方面具有重要作用。改革开放以来，中国城市迅速扩大，由此产生了诸多的河水水质退化的情况，城市河道成为主要的污染聚集地之一，主要体现在河道填占、水质下降、底泥淤积、生态恶化等方面，这些问题严重制约了社会经济的进步，对居民的日常生活造成干扰。因此，治理城市河道，并对其进行生态修复是当今城市环境整治的重要方面。本文以城市河道在可持续发展背景下要求建设生态城市为研究出发点，以城市河道为研究对象，在网上和图书馆收集相关资料的基础上，利用实地调查、归纳总结等研究方法，对城市河道治理与生态修复相关理论研究及其进展进行了整理，查阅了国内外城市河道的治理与生态修复的历程及现状。并以温州市温瑞塘河为具体案例，分析了流域内河流环境污染问题的成因，并提出了相应的防治方案。在此基础上，再利用相关的生态修复手段，包括河流护岸设计、曝气在河流中的应用以及生态浮岛等方面进行了对河流的生态修复研究。
As a Chinese saying goes, “Clear waters and lush mountains are invaluable assets”, ecology and environment are indispensable aspects on the road to sustainable development. In the age of urban civilization, the environmental condition of urban river was an important miniature of the urban environmental condition. The river plays an important role in flood control and drainage, irrigation, water transportation, recreation and so on. Since China’s reform and opening up, Chinese cities have expanded rapidly, creating a lot of river water quality degradation, urban river have become home to one of the main pollutions, mainly reflected in channel fill, declining water quality, sediment siltation, ecological deterioration, etc., these problems seriously restrict the social and economic progress, cause disturbance to residents’ daily life. Therefore, it is an important aspect of urban environmental regulation to harness urban river and restore its ecology. Based on urban runoff under the background of sustainable development requires construction of ecological city as a research starting point, with urban river as the research object, on the basis of related information collected on the Internet and library, using the methods of on-the-spot investigation and inductive summary, the theoretical studies related to harnessing and ecological restoration of urban river were organized, the course and present situation of urban river governance and ecological restoration at home and abroad were reviewed. Taking Wenruitang River in Wenzhou City as a case, this paper analyzes the causes of river environmental pollution and puts forward corresponding prevention and control schemes. On this basis, the relevant ecological restoration methods, including river revetment design, application of aeration in river and ecological floating island, are used to study the ecological restoration of river.
