【摘要】：本文旨在建構城市雨洪調蓄開放空間系統(tǒng),即結合現(xiàn)有的開放空間建立平災兩用的城市開放空間系統(tǒng),并借助空間可達性分析中的網(wǎng)絡分析法探究該系統(tǒng)的研究途徑,基于GIs的技術平臺,計算獲得雨洪調蓄數(shù)據(jù)及其調配分布情況,最終輔助市政排水工程,提出有效緩解城市內(nèi)澇問題的城市設計策略與措施。為驗證基于網(wǎng)絡分析的城市雨洪空間系統(tǒng)調蓄容量分析方法的可行性,本文將南京老城片區(qū)作為主要研究對象,分析闡述該區(qū)域內(nèi)的城市雨洪管理中出現(xiàn)的問題,結合前文所述的理論與方法,針對南京市實際暴雨積水情況,提出合理的城市雨洪調蓄開放空間設計方案。 全文可分為四個部分： 首先,回顧國內(nèi)外相關研究,分別歸納了城市開放空間基本理論與城市開放空問布局方法研究,為城市雨洪調蓄開放空間系統(tǒng)的建立及城市雨洪空間系統(tǒng)調蓄容量分析方法的提出提供理論支持。 其次,基于以上理論的研究分析,提出了城市雨洪調蓄開放空間系統(tǒng)的概念,并依據(jù)空間可達性分析方法中的網(wǎng)絡分析法,建立了基于網(wǎng)絡分析的城市雨洪空間系統(tǒng)調蓄容量分析方法及其計算模型,詳細闡述了城市雨洪調蓄開放空間系統(tǒng)容量分析的工作程序。進而辨析了基于網(wǎng)絡分析的空間可達性分析與基于網(wǎng)絡分析的城市雨洪調蓄開放空間系統(tǒng)調蓄容量計算分析的關系。 然后,以南京市老城區(qū)為例,建構真實場景下的城市雨洪調蓄開放空間系統(tǒng)。通過實地調研收集資料,分析研究區(qū)的城市開放空間現(xiàn)狀。借助GIs相關分析功能,建立基礎數(shù)據(jù)庫,運用定量分析方法計算雨洪調蓄開放空間的調蓄量,評價城市雨洪調蓄開放空間系統(tǒng)的調蓄能力。并且搜集相關專業(yè)對于雨水利用的實際案例,從城市設計與景觀學的視角,針對平災兩用的雨洪調蓄空間設計提出可行的操作策略。 最后,本文陳述了城市雨洪調蓄開放空間系統(tǒng)理論及其研究方法的可行性,并總結了研究中存在的不足和需要進一步探討的問題,明確了該系統(tǒng)未來的發(fā)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.
