【摘要】：我国正处在快速城市化发展阶段,高速城市化使得土地原有面貌发生了巨大改变,不透水表面的急剧增加,破坏了自然排水系统应对雨洪的能力。再加上传统以“快速排放”为主要目标的市政排水基础设施体制不健全,在全球气候变化的背景下,导致我国许多城市面临着洪涝灾害加剧、水污染严重等严峻的雨洪问题。公园作为城市建成环境中最大的绿色生态系统,具备雨洪管理的巨大潜力,但目前我国城市公园在雨洪管理方面普遍能力不足。发达国家自上世纪七十年代就已开始对城市雨洪问题进行研究,学习和引进先进的雨洪管理理念与技术,对缓解城市雨洪问题,探索适应我国城市发展的可持续雨洪管理方法具有重要现实意义。在我国大力推进海绵城市建设的背景下,低影响开发(Low Impact Development,LID)作为一种创新的综合雨洪管理战略和可持续的景观途径具有明显优势。通过合理的规划设计手段即能在源头上对雨水径流进行有效控制,而城市公园是其主要载体。本文首先分析了我国面临的严峻雨洪问题及其成因,并指出城市公园在雨洪管理方面存在的主要问题。然后通过相关文献的查阅和归纳,对海绵城市和可持续雨洪管理相关理论与实践进行了研究梳理,分析出在建设城市可持续雨洪管理体系过程中,雨洪管理向园林绿地拓展的趋势是毋庸置疑的,而建设具有主动雨洪管理功能的城市公园是其中的关键,应把雨洪管理纳入到公园景观设计的基本环节。论文以LID为主要理论支撑,重点论述了城市公园雨洪管理系统设计方法,对设计的原则目的、步骤、流程和主要内容等进行了具体说明,提出了一套基于LID的城市公园雨洪管理系统设计方法。最后通过相关实践案例,详细说明了基于现状条件进行设计的具体操作方式。通过对城市公园雨洪管理系统设计的研究,从景观设计领域拓展城市雨洪管理方式,期望能为LID在城市公园设计中的运用提供理论支持。使城市公园在具备休闲游憩、环境美化等主要功能的基础上,承担起重要的生态功能,发挥更大的复合价值,增强城市生命力,在一定程度上缓解城市严峻的雨洪问题。
[Abstract]:Our country is in the stage of rapid urbanization. The rapid urbanization changes the original appearance of the land dramatically increases the impervious surface and destroys the ability of the natural drainage system to cope with rain and flood. In addition, the traditional municipal drainage infrastructure system with "rapid discharge" as the main target is not perfect. Under the background of global climate change, many cities in China are faced with severe problems of rain and flood, such as aggravated flood disaster, serious water pollution and so on. As the largest green ecosystem in the urban built environment, parks have great potential for rainwater management, but at present, urban parks in our country are generally deficient in stormwater management. Developed countries have begun to study urban rain floods since the 1970s, learning and introducing advanced rain flood management concepts and techniques to alleviate urban rain flood problems. It is of great practical significance to explore sustainable stormwater management methods adapted to the development of cities in China. Under the background of promoting sponge city construction in China, low impact development has obvious advantages as an innovative comprehensive rain flood management strategy and sustainable landscape approach. Through reasonable planning and design means, Rain Water runoff can be effectively controlled at the source, and urban park is its main carrier. This paper first analyzes the severe rain flood problem in China and its causes, and points out the main problems in the rainwater management of urban parks. Then through the relevant literature review and induction, the sponge city and the sustainable rain flood management related theory and the practice have carried on the research combing, analyzed in the construction city sustainable rain flood management system process, There is no doubt that the trend of rain flood management expanding to garden green space, and the construction of urban park with active rain flood management function is the key, the rain flood management should be included in the basic link of park landscape design. With lid as the main theoretical support, this paper focuses on the design method of rain and flood management system in urban parks, and explains the principle, steps, flow and main contents of the design in detail. A design method of rain flood management system for urban park based on lid is presented. Finally, through the relevant practice cases, the detailed operation mode of the design based on the status quo condition is explained in detail. Through the research on the design of urban park rain flood management system, this paper develops the urban rain flood management mode from the landscape design field, hoping to provide theoretical support for the application of lid in the urban park design. On the basis of the main functions of recreation and beautification, the city park can take on the important ecological function, play more complex value, strengthen the city vitality, and alleviate the severe rain flood problem in the city to a certain extent.
