【摘要】：本文旨在建構(gòu)城市雨洪調(diào)蓄開(kāi)放空間系統(tǒng),即結(jié)合現(xiàn)有的開(kāi)放空間建立平災(zāi)兩用的城市開(kāi)放空間系統(tǒng),并借助空間可達(dá)性分析中的網(wǎng)絡(luò)分析法探究該系統(tǒng)的研究途徑,基于GIs的技術(shù)平臺(tái),計(jì)算獲得雨洪調(diào)蓄數(shù)據(jù)及其調(diào)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(wèn)題的城市設(shè)計(jì)策略與措施。為驗(yàn)證基于網(wǎng)絡(luò)分析的城市雨洪空間系統(tǒng)調(diào)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(duì)象,分析闡述該區(qū)域內(nèi)的城市雨洪管理中出現(xiàn)的問(wèn)題,結(jié)合前文所述的理論與方法,針對(duì)南京市實(shí)際暴雨積水情況,提出合理的城市雨洪調(diào)蓄開(kāi)放空間設(shè)計(jì)方案。 全文可分為四個(gè)部分： 首先,回顧國(guó)內(nèi)外相關(guān)研究,分別歸納了城市開(kāi)放空間基本理論與城市開(kāi)放空問(wèn)布局方法研究,為城市雨洪調(diào)蓄開(kāi)放空間系統(tǒng)的建立及城市雨洪空間系統(tǒng)調(diào)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(diào)蓄開(kāi)放空間系統(tǒng)的概念,并依據(jù)空間可達(dá)性分析方法中的網(wǎng)絡(luò)分析法,建立了基于網(wǎng)絡(luò)分析的城市雨洪空間系統(tǒng)調(diào)蓄容量分析方法及其計(jì)算模型,詳細(xì)闡述了城市雨洪調(diào)蓄開(kāi)放空間系統(tǒng)容量分析的工作程序。進(jìn)而辨析了基于網(wǎng)絡(luò)分析的空間可達(dá)性分析與基于網(wǎng)絡(luò)分析的城市雨洪調(diào)蓄開(kāi)放空間系統(tǒng)調(diào)蓄容量計(jì)算分析的關(guān)系。 然后,以南京市老城區(qū)為例,建構(gòu)真實(shí)場(chǎng)景下的城市雨洪調(diào)蓄開(kāi)放空間系統(tǒng)。通過(guò)實(shí)地調(diào)研收集資料,分析研究區(qū)的城市開(kāi)放空間現(xiàn)狀。借助GIs相關(guān)分析功能,建立基礎(chǔ)數(shù)據(jù)庫(kù),運(yùn)用定量分析方法計(jì)算雨洪調(diào)蓄開(kāi)放空間的調(diào)蓄量,評(píng)價(jià)城市雨洪調(diào)蓄開(kāi)放空間系統(tǒng)的調(diào)蓄能力。并且搜集相關(guān)專業(yè)對(duì)于雨水利用的實(shí)際案例,從城市設(shè)計(jì)與景觀學(xué)的視角,針對(duì)平災(zāi)兩用的雨洪調(diào)蓄空間設(shè)計(jì)提出可行的操作策略。 最后,本文陳述了城市雨洪調(diào)蓄開(kāi)放空間系統(tǒng)理論及其研究方法的可行性,并總結(jié)了研究中存在的不足和需要進(jìn)一步探討的問(wèn)題,明確了該系統(tǒng)未來(lái)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.
