【摘要】：本文旨在建构城市雨洪调蓄开放空间系统,即结合现有的开放空间建立平灾两用的城市开放空间系统,并借助空间可达性分析中的网络分析法探究该系统的研究途径,基于GIs的技术平台,计算获得雨洪调蓄数据及其调配分布情况,最终辅助市政排水工程,提出有效缓解城市内涝问题的城市设计策略与措施。为验证基于网络分析的城市雨洪空间系统调蓄容量分析方法的可行性,本文将南京老城片区作为主要研究对象,分析阐述该区域内的城市雨洪管理中出现的问题,结合前文所述的理论与方法,针对南京市实际暴雨积水情况,提出合理的城市雨洪调蓄开放空间设计方案。全文可分为四个部分：首先,回顾国内外相关研究,分别归纳了城市开放空间基本理论与城市开放空问布局方法研究,为城市雨洪调蓄开放空间系统的建立及城市雨洪空间系统调蓄容量分析方法的提出提供理论支持。其次,基于以上理论的研究分析,提出了城市雨洪调蓄开放空间系统的概念,并依据空间可达性分析方法中的网络分析法,建立了基于网络分析的城市雨洪空间系统调蓄容量分析方法及其计算模型,详细阐述了城市雨洪调蓄开放空间系统容量分析的工作程序。进而辨析了基于网络分析的空间可达性分析与基于网络分析的城市雨洪调蓄开放空间系统调蓄容量计算分析的关系。然后,以南京市老城区为例,建构真实场景下的城市雨洪调蓄开放空间系统。通过实地调研收集资料,分析研究区的城市开放空间现状。借助GIs相关分析功能,建立基础数据库,运用定量分析方法计算雨洪调蓄开放空间的调蓄量,评价城市雨洪调蓄开放空间系统的调蓄能力。并且搜集相关专业对于雨水利用的实际案例,从城市设计与景观学的视角,针对平灾两用的雨洪调蓄空间设计提出可行的操作策略。最后,本文陈述了城市雨洪调蓄开放空间系统理论及其研究方法的可行性,并总结了研究中存在的不足和需要进一步探讨的问题,明确了该系统未来的发展方向。
[Abstract]:The purpose of this paper is to construct the open space system of urban rain flood regulation and storage, that is, to establish the urban open space system with the existing open space, and to explore the research ways of the system by means of the network analysis method in the spatial accessibility analysis.Based on the technical platform of GIs, this paper calculates the rainwater storage data and its distribution, finally assists municipal drainage works, and puts forward the urban design strategies and measures to effectively alleviate the urban waterlogging problem.In order to verify the feasibility of the capacity analysis method of urban rain flood spatial system based on network analysis, this paper takes the old city of Nanjing as the main research object, and analyzes and expounds the problems in the urban rain flood management in this area.Based on the theory and method mentioned above, a reasonable design scheme of urban storm-flood regulation and storage open space is put forward in view of the actual rainstorm water accumulation in Nanjing.The full text can be divided into four parts:First of all, reviewing the relevant research at home and abroad, the basic theory of urban open space and the research of urban open space layout are summarized respectively.It provides theoretical support for the establishment of urban stormwater storage open space system and for the analysis method of urban stormwater storage capacity.Secondly, based on the research and analysis of the above theory, the concept of urban stormwater storage open space system is put forward, and the network analysis method of spatial reachability analysis method is used.Based on network analysis, the capacity analysis method of urban stormwater storage space system and its calculation model are established, and the working program of capacity analysis of urban stormwater storage open space system is described in detail.Furthermore, the relationship between the spatial reachability analysis based on network analysis and the calculation and analysis of the storage capacity of urban stormwater storage open space system based on network analysis is analyzed.Then, taking the old urban area of Nanjing as an example, the open space system of urban rain flood regulation and storage is constructed.Through field investigation and data collection, the paper analyzes the status of urban open space in the research area.With the help of the related analysis function of GIs, the basic database is established, and the quantity of stormwater storage in open space is calculated by using quantitative analysis method, and the capacity of regulating and storing in urban open stormwater storage system is evaluated.From the perspective of urban design and landscape science, this paper puts forward feasible operational strategies for the design of rainwater flood storage space in the light of urban design and landscape science.Finally, this paper describes the feasibility of the theory and research methods of urban rain-flood regulation and storage open space system, summarizes the shortcomings of the research and the problems that need to be further explored, and clarifies the future development direction of the system.
