【摘要】:伴隨著城市經(jīng)濟(jì)的高速發(fā)展,城市建設(shè)的速度隨之加快,繼而城市空間形態(tài)演化迅速。城市空間形態(tài)的快速演化就會(huì)帶來(lái)一系列城市問(wèn)題,例如城市人口膨脹,城市特色景觀破壞、城市土地開(kāi)發(fā)過(guò)快等,傳統(tǒng)的城市規(guī)劃理論在新環(huán)境下已經(jīng)不能解決上述問(wèn)題,同時(shí)城市空間形態(tài)的快速演變也對(duì)規(guī)劃工作帶來(lái)新的挑戰(zhàn),需要更科學(xué)的規(guī)劃理論和方法去研究和解決上述問(wèn)題。 本論文基于歷年以及近期的遙感影像,,通過(guò)相關(guān)軟件處理解譯后獲得重慶市主城區(qū)歷年建成區(qū)、建設(shè)用地的圖斑,進(jìn)行統(tǒng)計(jì)后獲得建成區(qū)、建設(shè)用地?cái)?shù)據(jù)。本文將城市空間形態(tài)的衡量指標(biāo)分為內(nèi)部和外部指標(biāo)來(lái)分別研究,進(jìn)一步深入發(fā)現(xiàn)空間形態(tài)的演變特征和內(nèi)在規(guī)律。在獲得數(shù)據(jù)后運(yùn)用擴(kuò)張強(qiáng)度、擴(kuò)展方向、緊湊度、多樣性指數(shù)對(duì)城市外部空間形態(tài)進(jìn)行分析研究,運(yùn)用建設(shè)用地布局結(jié)構(gòu)數(shù)據(jù)對(duì)內(nèi)部空間形態(tài)進(jìn)行研究。在對(duì)重慶市的城市現(xiàn)狀以及空間形態(tài)演化規(guī)律有清晰的了解后,基于現(xiàn)狀對(duì)現(xiàn)行的規(guī)劃進(jìn)行評(píng)估,明確城市發(fā)展程度,城市發(fā)展是否與總體規(guī)劃相匹配,整體發(fā)展速度是否合理。在對(duì)現(xiàn)狀進(jìn)行評(píng)估后,結(jié)合人口、經(jīng)濟(jì)數(shù)據(jù)與城市空間形態(tài)數(shù)據(jù)綜合分析,并預(yù)測(cè)空間形態(tài)的變化趨勢(shì),在空間上更加直觀形象的研究探索。 通過(guò)論文的研究,主要得出以下結(jié)論:(1)重慶市主城區(qū)外部空間形態(tài)保持健康發(fā)展趨勢(shì),內(nèi)部城市空間形態(tài)布局趨于合理,但仍存在調(diào)整空間;(2)城市規(guī)劃對(duì)城市空間形態(tài)變化具有明顯的引導(dǎo)調(diào)控作用,引導(dǎo)和推動(dòng)著城市空間結(jié)構(gòu)的形成與擴(kuò)展。之后通過(guò)對(duì)現(xiàn)狀的規(guī)劃評(píng)估,發(fā)現(xiàn)了存在的問(wèn)題。(3)根據(jù)主城區(qū)城市空間形態(tài)的現(xiàn)狀分析、演變分析、發(fā)展趨勢(shì)分析和存在的問(wèn)題,提出了相應(yīng)的城市規(guī)劃工作建議,完善了城市規(guī)劃理論體系。
[Abstract]:With the rapid development of urban economy, the speed of urban construction accelerates, and the urban spatial form evolves rapidly. The rapid evolution of urban spatial form will bring a series of urban problems, such as urban population expansion, urban landscape damage, urban land development and so on. The traditional urban planning theory can not solve the above problems under the new environment. At the same time, the rapid evolution of urban spatial form also brings new challenges to the planning work, which requires more scientific planning theory and methods to study and solve the above problems. Based on the remote sensing images of the past years and recent years, this paper obtains the plot of the building area and the construction land of Chongqing's main urban area after interpretation by the relevant software, and obtains the data of the building area and the construction land after statistics. In this paper, the measurement index of urban spatial form is divided into internal and external indexes, and the evolution characteristics and internal law of spatial form are further discovered. After obtaining the data, the expansion intensity, expansion direction, compactness and diversity index were used to analyze and study the urban outer spatial form, and the internal spatial form was studied by using the construction land layout structure data. After having a clear understanding of the urban status quo and the evolution law of spatial form in Chongqing, the current planning is evaluated based on the present situation, and the degree of urban development and whether the urban development is matched with the master plan are determined. Whether the overall speed of development is reasonable. After evaluating the present situation, combined with the data of population, economy and urban spatial form, the author makes a comprehensive analysis, and predicts the change trend of spatial form, and explores more intuitionistic image in space. Through the research of this paper, we can draw the following conclusions: 1) the outer spatial form of Chongqing's main urban area keeps a healthy development trend, and the layout of internal urban spatial form tends to be reasonable. However, there is still a significant role of urban planning in guiding and regulating the change of urban spatial form, guiding and promoting the formation and expansion of urban spatial structure. Then through the planning evaluation of the present situation, found the existing problems. (3) according to the present situation analysis, evolution analysis, development trend analysis and existing problems of the urban space form of the main urban area, put forward the corresponding suggestions for urban planning work. The theoretical system of urban planning has been improved.
