【摘要】：中国作为发展中的大国,近年来许多城市频繁遇到城市内涝问题。快速城市化进程中城市建成区过大、不可渗透地面过多、市政设施不完善,雨水管网设计标准过低等因素造成城市地表雨水径流量过大。我国城市面临的水生态问题不仅仅是洪涝灾害,还面临着严峻的水资源短缺和水污染问题,因此国家提出海绵城市的概念。其中城市人工湿地这样一种兼具净化、调蓄、景观等多元化功能的绿色基础设施在海绵城市的建设中必将起到不可替代的作用。现在在人工湿地的建设上有两种趋势:风景园林学科设计的人工湿地更多的关注景观效果,但对污染物的控制往往达不到理论上的效果。环境学科从污染物去除的有效性方面出发,但景观视觉效果不理想。本研究的目的是在用地紧张的城市中使人工湿地在海绵城市的背景下发挥其综合性功能:净水功能、蓄水功能、景观功能、科普功能等。这种多功能的发挥,就需要兼顾景观效果和生态效益这两个方面。本文首先对国内外海绵城市及人工湿地的相关概念进行梳理,并对相关案例进行分析,总结已建成的城市人工湿地的优缺点。第二,选取北京市奥林匹克森林公园人工湿地、玉渊潭人工湿地和颐和园葫芦河为研究对象,通过全年水质监测、径流模拟、调研分析等方式对人工湿地污染物控制能力、径流控制能力和景观效果三个方面进行分析研究。发现研究区人工湿地TP均严重超标;污染控制能力:奥林匹克森林公园人工湿地玉渊潭湿地葫芦河;径流调蓄能力:奥森葫芦河玉渊潭;景观效果:玉渊潭奥森葫芦河。针对研究区人工湿地在运行中存在的问题,分析其原因并提出相应的改善策略。第三,根据对文献、国内外案例、实地监测等的分析研究提出海绵城市背景下城市人工湿地实现净水、蓄水、景观等多元化功能的综合设计建议,为今后海绵城市建设中城市人工湿地的建设提供参考。第四,选取西宁市湟水河人工湿地项目对论文中的海绵城市人工湿地设计方法进行实践应用和验证。
[Abstract]:As a developing country, in recent years, many cities in China frequently encounter urban waterlogging problems. In the process of rapid urbanization, the urban built-up areas are too large, the impermeable surface is too much, and the municipal facilities are not perfect. The design standard of rainwater pipe network is too low and other factors cause the urban surface Rain Water runoff is too large. The water ecological problems faced by cities in China are not only flood disasters, but also severe water resources shortage and water pollution problems. Therefore, the state put forward the concept of sponge city, among which the urban constructed wetland is a kind of purifying and regulating. Green infrastructure with multiple functions such as landscape will play an irreplaceable role in the construction of sponge city. There are two trends in the construction of constructed wetland:. The artificial wetland designed by the subject of landscape architecture pays more attention to the landscape effect. However, the control of pollutants is often not effective in theory. The environmental discipline starts from the effectiveness of pollutant removal. But the visual effect of landscape is not ideal. The purpose of this study is to make the constructed wetland play its comprehensive functions in the background of sponge city in the city where land use is tight: water purification function, water storage function, landscape function. Science popularization function and so on. This kind of multi-function play, need to take into account the landscape effect and ecological benefits of these two aspects. Firstly, this paper reviews the concepts of sponge cities and constructed wetlands at home and abroad. And analysis of relevant cases, summed up the advantages and disadvantages of the constructed urban wetland. Second, select Beijing Olympic Forest Park constructed wetland, Yuyuantan constructed wetland and the Summer Palace Hulu River as the research object. Through the whole year water quality monitoring, runoff simulation, investigation and analysis and other ways to control pollutants in constructed wetlands. The runoff control ability and landscape effect were analyzed and studied. It was found that the TP of constructed wetland in the study area exceeded the standard seriously. Pollution control capacity: Olympic Forest Park constructed wetland Yuyuantan wetland Hulu River; Runoff regulation and storage capacity: Orson Hulu River Yuyuantan; Landscape effect: Yuyuantan Orson Hulu River. In view of the problems existing in the operation of the constructed wetland in the research area, analyze the reasons and put forward the corresponding improvement strategy. Third, according to the literature, domestic and foreign cases. Field monitoring analysis and research on the background of sponge city constructed wetland to achieve water purification, water storage, landscape and other diverse functions of comprehensive design recommendations. This paper provides a reference for the construction of constructed wetland in sponge city in the future. 4th, the project of Huangshui River constructed wetland in Xining city is selected to practice and verify the design method of constructed wetland in sponge city.
