【摘要】：自然水空間是自然生態(tài)過程與水文過程發(fā)生耦合的承載空間,在我國快速城市化進程中,自然水空間被人為改造,其原本的自然過程產(chǎn)生了相應(yīng)變化,切斷了城市與自然之間的生態(tài)聯(lián)系,由此引發(fā)水資源、水安全、水生態(tài)等問題。對城市水問題綜合解決的首要工作是城市水空間體系的生態(tài)化修復(fù),而城市水空間體系生態(tài)化修復(fù)的前提,則是:對自然水空間生態(tài)水文過程的認識,對城市水空間受擾機制的理解,進而預(yù)測與自然生態(tài)環(huán)境和諧的城市水空間圖景。本研究首先引入生態(tài)水文學(xué)的生態(tài)水文過程理論,認識自然生態(tài)水文過程與自然水空間格局之間的契合關(guān)系,歸納出地表水的匯流、運移、蓄積三大過程與水空間格局演變的相關(guān)性;然后,以自然生態(tài)水文過程與自然水空間格局之間的契合關(guān)系為參照,理解城市地表水的匯流、運移、蓄積過程與相應(yīng)空間的變化,發(fā)現(xiàn)順應(yīng)生態(tài)水文過程的城市水空間體系的缺失,是引發(fā)城市水生態(tài)問題的關(guān)鍵;提出修復(fù) 匯流‖、 通道‖、 節(jié)點‖和 循環(huán)‖等四大城市生態(tài)水文過程的方法體系,探索城市水空間體系生態(tài)化修復(fù)中的水網(wǎng)修復(fù)、濕地體系構(gòu)建等主要內(nèi)容以及尺度界定、水網(wǎng)模擬、濕地尋找等關(guān)鍵技術(shù);最后,在成都市新都區(qū)北部商城水空間體系規(guī)劃中,加以應(yīng)用驗證。本研究對城市水資源、水安全、水生態(tài)、水環(huán)境問題的全面求解,從物質(zhì)空間的體系層面,從理念及方法的生態(tài)轉(zhuǎn)型方面,進行了積極的探索,對我國生態(tài)城市、海綿城市等建設(shè),具有一定的理論和實踐意義。論文分為六章:第一章,闡述了研究的背景、目的和意義,并對城市水空間、生態(tài)水文過程等概念進行了界定,明確了研究方法和研究內(nèi)容。第二章,介紹了城市水空間體系構(gòu)建的基礎(chǔ)研究和相關(guān)方法,總結(jié)了國內(nèi)外城市水空間體系構(gòu)建的思維轉(zhuǎn)變及先進經(jīng)驗,指出現(xiàn)有方法體系下需深化的要點和存在的不足。第三章,通過對比自然理想水空間格局,分析生態(tài)水文過程下水的匯流、運移、蓄積三大過程與相應(yīng)空間格局契合關(guān)系在城市中的變化,歸納城市水空間問題的成因,提出了多尺度下的城市生態(tài)水文過程修復(fù)策略。第四章,基于修復(fù)城市水空間體系的功能性缺失,提出了城市水空間的 匯流‖、 通道‖、 節(jié)點‖、 循環(huán)‖四大體系的修復(fù)方法,構(gòu)建出能夠承載城市水資源匯流、運移、蓄積三大過程的生態(tài)水空間,并提出了相應(yīng)的水循環(huán)保障措施。該部分研究運用GIS平臺的Arc SWAT分布式水文模型,通過建立城市數(shù)字高程模型,模擬城市水空間,提出了城市流域、水網(wǎng)格局、濕地格局重塑的相應(yīng)方法。第五章,以參與項目《成都市新都區(qū)北部商城水空間體系規(guī)劃》為例,結(jié)合實際情況,對城市水空間體系構(gòu)建方法加以應(yīng)用,驗證其可行性并完善其理論研究。第六章,對研究成果進行總結(jié)以及討論。
[Abstract]:Natural water space is the carrying space where the natural ecological process and the hydrological process are coupled. In the process of rapid urbanization in China, the natural water space has been artificially transformed, and its original natural process has changed accordingly. The ecological connection between city and nature is cut off, which leads to water resources, water safety, water ecology and so on. The most important task to solve the urban water problem is ecological restoration of urban water space system, and the premise of ecological restoration of urban water space system is the understanding of ecological hydrological process of natural water space. Understanding the disturbed mechanism of urban water space and predicting the urban water space picture in harmony with natural ecological environment. In this study, the theory of ecological hydrological process is introduced to understand the relationship between the natural ecological hydrological process and the spatial pattern of natural water, and the confluence and migration of surface water are concluded. Based on the relationship between the natural eco-hydrological process and the spatial pattern of natural water, the confluence, migration, accumulation process of urban surface water and the change of the corresponding space are understood by reference to the relationship between the natural eco-hydrological process and the spatial pattern of natural water. It is found that the lack of urban water space system conforming to the ecological hydrological process is the key to the urban water ecological problem. This paper puts forward a method system for repairing the eco-hydrological process of four major cities, such as confluence, channel, node and cycle, and explores the restoration of water network in the ecological restoration of urban water space system. The key technologies such as the construction of wetland system, the definition of scale, the simulation of water network, the search of wetland and so on. Finally, it is applied in the planning of water space system of Shangcheng city in the north of Xindu district of Chengdu. This research has carried on the active exploration to the city water resources, the water safety, the water ecology, the water environment question, from the material space system level, from the idea and the method ecology transformation aspect, has carried on the active exploration to our country ecology city, Sponge city construction has certain theoretical and practical significance. The thesis is divided into six chapters: the first chapter describes the background, purpose and significance of the study, and defines the concepts of urban water space and ecological hydrological process, and clarifies the research methods and contents. The second chapter introduces the basic research and related methods of urban water space system construction, summarizes the thinking transformation and advanced experience of urban water space system construction at home and abroad, and points out the key points and shortcomings of the existing method system. In the third chapter, by comparing the natural ideal water spatial pattern, the author analyzes the change of the confluence, migration and accumulation of the water in the ecological hydrological process and the corresponding spatial pattern in the city, and sums up the causes of the urban water space problem. The restoration strategy of urban eco-hydrological process on multiple scales is put forward. In the fourth chapter, based on the functional deficiency of the urban water space system, the restoration methods of the four urban water space systems, namely, the confluence of the urban water space, the channel, the node, the loop and so on, are put forward, which can carry the confluence of the urban water resources. The ecological water space of the three processes of migration and accumulation, and the corresponding protection measures of water circulation are put forward. In this part, the distributed hydrological model of Arc SWAT based on GIS platform is studied. Through the establishment of urban digital elevation model, the urban water space is simulated, and the corresponding method of rebuilding urban watershed, water network pattern and wetland pattern is put forward. In the fifth chapter, taking the project "Planning of Water Space system in Northern Commercial City of Chengdu" as an example, combining with the actual situation, the author applies the method of constructing urban water space system, verifies its feasibility and perfects its theoretical research. Chapter six summarizes and discusses the research results.
