【摘要】：随着城市新区开发建设不断加快,传统的新区规划建设方法忽略对水环境的保护及利用,导致新区水环境污染,不透水地面急剧增加,城市洪水频发,城市的发展与生态资源环境未能和谐共存等问题。为了弥补传统新区规划设计的不足,本文将引入海绵城市理念,引导和调控城市新区规划设计,为城市新区规划建设提供的新思路,实现城市新区开发建设与资源环境保护的平衡。作为全国海绵城市建设的试点城市,本论文研究的对象是南宁市新区昆仑大道片区规划。首先,文章阐述了海绵城市、低影响开发、生态城市的概念和内涵特征,简单概括了 LID与海绵城市、海绵城市与生态城市的关系。对LID场地规划设计理论,海绵城市相关理论进行研究,归纳出海绵城市新区规划的3个原则,明确新区规划需要落实的控制目标,总结目标落实5点思路和5点规划方法以及LID场地规划的5个设计理念和4个设计方法。其次,在相关理论学习的基础上,深刻剖析了4例国内外海绵城市规划实践案例,从旧区重建和新区规划两方面了解了具体的设计方法,总结经验并从中获得4点启示。再次,将海绵城市理论和实践的研究运用到昆仑大道新区规划中。通过结合GIS、湘源软件模拟地形、汇水特征、自然排水分区,结合水系植被分布识别昆仑大道片区的海绵本底,构建海绵格局、确定海绵功能区划,提出海绵城市建设目标,具体为年径流总量那平江流域≥75%、四塘江流域≥80%;水面率≥18%;绿地率≥38.99%;排水防涝标准为30年一遇。最后,得到昆仑大道片区新区规划成果。通过水文循环构建生态格局以水循环为主线,提出“一带两轴,四廊五组”规划布局结构,土地利用布局遵循新区自然地形,路网适应水系,绿化与水系道路结合分散渗透,分区排水,创造开放空间,力求在城市新区开发建设和自然环境资源保护两个方面实现共赢。论文试图将海绵城市理论融入城市新区规划中,探寻新区规划实践新方法和新思路,为未来城市新区的规划设计与海绵城市建设提供参考与借鉴。
[Abstract]:With the rapid development and construction of new urban areas, the traditional planning and construction of new areas ignore the protection and utilization of the water environment, resulting in the water environment pollution, impermeable surface of the rapid increase, frequent urban floods. In order to make up for the deficiency of traditional new district planning and design, this paper will introduce the concept of sponge city to guide and regulate the planning and design of new urban area. It provides a new way of thinking for the planning and construction of new urban districts and realizes the balance between the development and construction of new urban areas and the protection of resources and environment. It is a pilot city for the construction of sponge cities in China. The object of this paper is the planning of Kunlun Avenue in Nanning New District. Firstly, the paper expounds the concept and connotation of sponge city, low impact development, ecological city, and summarizes the concept and connotation of LID and sponge city. The relationship between sponge city and ecological city. This paper studies the theory of LID site planning and design, and summarizes the three principles of sponge city new area planning. Clear the new area planning needs to implement the control objectives, summed up the implementation of the goal 5 ideas and 5 points of planning methods, LID site planning 5 design concepts and 4 design methods. Secondly. Based on the study of relevant theories, this paper deeply analyzes four cases of sponge urban planning practice at home and abroad, and understands the specific design methods from the two aspects of old district reconstruction and new area planning. Summing up the experience and obtaining 4 enlightenment. Thirdly, the theory and practice of sponge city is applied to the planning of Kunlun Avenue New area. By combining GIS-Xiangyuan software to simulate the terrain, catchment characteristics. Natural drainage zoning, combined with the distribution of water vegetation to identify the sponge background of Kunlun Avenue area, to construct sponge pattern, to determine the sponge functional zoning, and to put forward the construction objectives of sponge city. The total annual runoff in the Naping River basin is more than 75, and that in the Sitang River basin is 鈮，
