【摘要】：目前,我国正大力推广建设海绵城市,多部委相继出台了多个政策及文件。本文探讨在海绵城市视角下,数量可观的口袋公园的提升改造成城市海绵体的模式与方法,旨在提高城市海绵体落实的可实施性,加快海绵城市的建设。本文分为三个部分来论述口袋公园通过提升改造,实现海绵化的全过程。本文通过对目前频发的城市雨水内涝现在进行总结和梳理,找到其频发的根本原因,针对根本原因进行思考。通过对城市海绵体概念、范畴的解读,以及对口袋公园概念、面积、功能、划分类型等相关概念的界定,明确研究目的及意义,界定研究对象,总结出二者均具有人口密度的高敏感性、离散状分布、均好性三个核心特征。在此基础上进行了口袋公园与城市海绵体的关联性研究,分别从可能性和紧迫性两个方面进行论述。通过已建成的实际案例进行佐证,验证二者的关联性。本文以深圳市为例,依据深圳市年径流总量控制率及其对应的设计降雨量,运用雨水设施规模中容积法的计算公式,将海绵口袋公园的雨水调蓄划分为三种模式,分别为独立内部调蓄模式、区域协作调蓄模式、外部系统调蓄模式,适用于不同年径流总量控制率要求下的海绵口袋公园设计。文章通过运用德尔菲法对影响海绵口袋公园选址的因素进行敏感性排序,得到其最为敏感的3个影响因素,并依据此因素判断深圳市海绵口袋公园的最佳建设区域。运用层次分析法,对口袋公园的设施选择影响因子进行层次结构体系的架构,利用判别矩阵得到各个指标的相对权重值。依据对口袋公园内部单项设施多个方面的详细评估,利用评分体系对各个单项设施进行打分排序,得到最适宜建设的单项设施。将所得结论应用于实际案例设计中,作为口袋公园雨水设施选择的依据,完成口袋公园的海绵化提升。
[Abstract]:At present, China is vigorously promoting the construction of sponge cities, many ministries have issued a number of policies and documents. This paper discusses the mode and method of transforming a considerable number of pocket parks into urban sponges from the perspective of sponge cities in order to improve the implementability of urban sponge bodies and speed up the construction of sponge cities. This paper is divided into three parts to discuss the whole process of sponging through upgrading the pocket park. In this paper, the author summarizes and combs the frequent waterlogging in the city Rain Water at present, finds out the root cause of the frequent waterlogging, and thinks about the root cause. By analyzing the concept and category of urban spongiform, and defining the concept of pocket park, area, function, classification and other related concepts, the purpose and significance of the study and the definition of research object are defined. It is concluded that both of them have three core characteristics of high sensitivity, discrete distribution and good quality of population density. On this basis, the relationship between pocket park and urban cavernous body is studied, which is discussed from two aspects: possibility and urgency. The correlativity between the two is verified by the actual cases that have been built. In this paper, taking Shenzhen as an example, according to the total runoff control rate and its corresponding design rainfall in Shenzhen City, and using the calculation formula of volume method in Rain Water facility scale, this paper divides Rain Water regulation and storage in Sponge pocket Park into three models. They are independent internal storage mode, regional cooperative storage mode and external system storage mode, which are suitable for the design of Sponge pocket park under the requirement of runoff total control rate in different years. In this paper, the factors influencing the location of sponge pocket park are ranked by Delphi method, and the three most sensitive factors are obtained, according to which the best construction area of sponge pocket park in Shenzhen is judged. The hierarchy process is used to construct the hierarchy structure of the influencing factors of facility selection in the pocket park, and the relative weights of each index are obtained by using the discriminant matrix. According to the detailed evaluation of the single facility in the pocket park, the single facility is ranked by using the scoring system, and the single facility that is most suitable for construction is obtained. The conclusion is applied to the practical case design as the basis for the selection of Rain Water facilities in the pocket park to complete the sponging promotion of the pocket park.
