Study On Urban Water System Space In Guangzhou

Guangzhou, located in South China Sea coast, is the confluence of three rivers. With dense water network and staggered waterways, the development of Guangzhou has been closely related to the evolution of the urban water system. The historical evolution of Guangzhou urban water system space, problems encountered in the process of the contemporary water system space construction from macro to micro, all of these are typical in our country. Therefore, taking Guangzhou urban water system space as the research object, has important theory significance and practical value.The study time limits is from the founding of the city until the present, with emphasis on modern; and the study spatial extent based on built-up area, focus on downtown Guangzhou and its urban fringe.The research methods include literature study and research, field survey, regional cultural learning, questionnaire survey, comparative analysis.Based on the relationship between the city development and the water system evolution, the thesis is mainly composed of the following five chapters:Chapter Two is the research on the development process of the city development and the water system evolution from the historical development level. From the founding of the city up to now, every major city structural adjustment, the water system construction have made the appropriate changes, and sometimes even have guided the development of the city. Through the review of the water system development and urban relations, it offers historical reference, and lay a solid foundation for below.Chapter Three analyzes the structure of Guangzhou urban water system from the physical form level. In this chapter, the Overall landform, the new look of water network combined with green network and road network are discussed. At the same time, Guangzhou Pearl River Waterfront space, the waterfront settlement space and the waterfront settlement landscape space are studied in-depth.Chapter Four is a case study. From the engineering practice level, typical cases of river system, river-and-creek system and lake system are classified selected and researched. From macro point of view, the relationship of water system evolution and urban development, structural adjustment is analyzed. From meso and micro point of view, in the practice of engineering, history and culture, city texture, residents living, ecological environment, landscape features and other aspects are discussed, and Post-Occupancy evaluation is taken as well. Chapter Five is the study of technical measures. From the construction and implementation level, in line with the ecology-oriented and landscape-oriented principle, three factors were selected to study the localization method, including the section form, the revetment structure, and measures combined with water ecological restoration. For every factors, cases of typical site characteristics, good effect, wide application prospect are chosen and discussed. The discussion both focuses on the principle and application effect of a single technology, and also introduces the integrated use of effects under different conditions.Last but not least, based on the above four-parts of studies, the implementation pathway of constructing Guangzhou urban water system space is analyzed. By combining the actual situation of Guangzhou and learning from some successful cases,five factors are chosen and discussed.For the case in Guangzhou, it is a new direction of selecting the relationship between the city development and the water system evolution as the entry point of the study. In this thesis, the combing of the urban water system evolution history, enrich the basis of the research data. At the same time, it can be regarded as a phased research results, case analysis and summary can lay a solid foundation for further research.
