【摘要】：城市擴展是城市在各種內(nèi)外動力作用下的空間推進,其過程不僅僅是簡單的物理過程,而是在自然地理、社會經(jīng)濟等多方面因素相互影響、共同作用下形成的一種有機增長過程,而跨江河發(fā)展則是城市空間結(jié)構(gòu)擴展的一種特殊形式。從國內(nèi)外沿江河流域城市的擴展規(guī)律可以發(fā)現(xiàn),當城市發(fā)展到一定階段時,沿江河城市就會從沿江發(fā)展走向跨江發(fā)展,最終走向擁江發(fā)展�？缃l(fā)展已成為沿江發(fā)展城市擴展城市空間、優(yōu)化城市結(jié)構(gòu)、提升城市競爭力的重要舉措。 本文以不同時期長沙市城區(qū)的土地利用現(xiàn)狀圖、規(guī)劃圖、遙感影像圖為基礎(chǔ),運用GIS空間分析方法和多元統(tǒng)計分析法等研究方法,從時間序列、空間結(jié)構(gòu)形態(tài)演變等方面對長沙市跨江發(fā)展的演變過程進行系統(tǒng)的分析,將長沙市的跨江發(fā)展劃分為6個階段,并結(jié)合自然地理、社會經(jīng)濟發(fā)展情況以長沙市跨江發(fā)展的推動力和制約因素兩個方面為切入點,從人口與社會經(jīng)濟發(fā)展、交通條件、政府支持、外在需求與各種引力等方面深入探討長沙市跨江發(fā)展的作用機制�；陂L沙市跨江發(fā)展的歷程與作用機制,結(jié)合長沙市跨江發(fā)展的現(xiàn)狀條件,以及跨江發(fā)展會引發(fā)什么樣的問題,并依據(jù)國內(nèi)外跨江發(fā)展城市的實踐與經(jīng)驗教訓(xùn),提出了長沙市實施和推進跨江發(fā)展的主要策略。結(jié)果表明： (1)長沙市跨江發(fā)展的演變歷程可劃分為6個階段：1949年以前的沿江發(fā)展階段、1949-1965年的萌芽發(fā)展階段、1965-1978年的初期發(fā)展階段、1978-1989年的緩慢發(fā)展階段、1989-2008年的加速發(fā)展階段、2008年至今的全面加速推進階段。 (2)長沙市跨江發(fā)展過程的驅(qū)動機制：①長沙市自身經(jīng)濟發(fā)展是持久連續(xù)的動力,這種動力伴隨著長沙市經(jīng)濟發(fā)展實力的增強而強化,反之,城市的跨江河發(fā)展又會帶動經(jīng)濟的發(fā)展；②各級政府通過行政、規(guī)劃等政策手段是長沙市跨江發(fā)展的直接推動力,這種動力一般具有明顯的目的導(dǎo)向性,其所起作用的大小取決于政府的推動力度；③長沙市河西區(qū)域的吸引力及城市發(fā)展引發(fā)的各個方面對跨江河發(fā)展的需求對長沙市跨江發(fā)展的推動作用明顯,此作用力直接關(guān)系到城市跨江河發(fā)展的效率和進程。隨著長沙市經(jīng)濟水平的不斷發(fā)展,政府在推動城市跨江河發(fā)展過程中的作用相對來講趨于弱化,而城市的內(nèi)生推動力經(jīng)濟的發(fā)展將會逐漸成為城市跨江河發(fā)展最根本的推動力。本文將長沙市跨江河發(fā)展的阻力主要歸結(jié)于自然地理條件的限制、技術(shù)經(jīng)濟條件的限制。隨著社會經(jīng)濟的發(fā)展以及科學(xué)技術(shù)水平的不斷提高,自然地理條件以及技術(shù)設(shè)施條件的制約作用趨于弱化,城市經(jīng)濟發(fā)展水平成為制約長沙市跨江發(fā)展的關(guān)鍵因素。 (3)依據(jù)國內(nèi)外跨江發(fā)展城市的實踐與經(jīng)驗教訓(xùn),并結(jié)合長沙市跨江發(fā)展的現(xiàn)狀條件,及跨江發(fā)展過程中可能引發(fā)的問題,對長沙市推進跨江發(fā)展提出了四點建議：①加快構(gòu)建完善的交通網(wǎng)絡(luò)系統(tǒng)；②推進區(qū)域聯(lián)動整合,處理好區(qū)域功能互補性與獨立性；③實施濱水區(qū)域的合理開發(fā),實現(xiàn)“山、水、洲、城”的有機融合；④省市政府需提供持續(xù)的政策支持。
[Abstract]:Urban expansion is a space propulsion under the action of various internal and external forces. The process of urban expansion is not only a simple physical process, but also an organic growth process formed under the interaction of many factors such as natural geography, social economy and other factors. The development of the river is a special form of the expansion of urban space structure. The expansion law of the cities along the river valley at home and abroad can be found that, when the city develops to a certain stage, the city will develop from the river along the river to the cross river development, and eventually to the development of the river, which has become an important measure to expand the city space along the river, optimize the urban construction, and enhance the competitiveness of the city.
This paper, based on the land use status map of Changsha city in different periods, based on the planning map and remote sensing image, uses the methods of GIS spatial analysis and multivariate statistical analysis to systematically analyze the evolution process of Changsha city's cross river development from the time series and the evolution of the spatial structure form, and the trans Jiang hair of Changsha city. The exhibition is divided into 6 stages, and combined with the natural geography and social and economic development, the driving force and restriction factors of Changsha's cross river development are the starting point. From the aspects of population and social and economic development, traffic conditions, government support, external demand and various gravitational forces, the mechanism of the cross river development in Changsha is discussed. Based on Changsha, The process and mechanism of the cross river development in the city, combined with the current conditions of Changsha's cross river development, and what kind of problems will be caused by the cross river development, and according to the practice and experience of the cities across the river at home and abroad, put forward the main strategy to implement and promote the development of the river across the river in Changsha. The results show that:
(1) the evolution process of Changsha's cross river development can be divided into 6 stages: the development of the river along the river before 1949, the stage of germination and development of 1949-1965 years, the initial stage of 1965-1978 years, the slow development stage of 1978-1989 years, the accelerated development stage of 1989-2008 years, and the comprehensive acceleration and promotion stage from 2008 to the present.
(2) the driving mechanism of Changsha's cross river development process: (1) Changsha's own economic development is a lasting and continuous driving force, which is accompanied by the strengthening of the strength of Changsha's economic development. On the contrary, the development of the city's cross river development will lead to the economic development. (2) the government at all levels through administration, planning and other policies are the trans River in Changsha. The direct driving force of development, this kind of motive force generally has obvious goal orientation, the size of its function depends on the impetus of the government; thirdly, the attraction of the Hexi region of Changsha city and the development of the city caused by the urban development have an obvious effect on the cross river development in Changsha. With the continuous development of the economic level of Changsha, the role of the government in promoting the development of the city across the river tends to weaken, and the development of the urban endogenous driving economy will gradually become the most fundamental driving force for the development of the cities across the river. This paper will cross the river in Changsha. The resistance of development is mainly due to the limitation of natural geographical conditions and the restriction of technical and economic conditions. With the development of the social economy and the continuous improvement of the level of science and technology, the constraints of the natural geographical conditions and the conditions of technical facilities tend to weaken, and the level of urban economic development has become the key factor restricting the development of Changsha's cross river.
(3) according to the practice and experience of the cities across the river at home and abroad, and combining the present conditions of Changsha's cross river development and the possible problems in the process of cross river development, four suggestions are put forward to promote the development of cross river development: (1) speeding up the construction of a perfect traffic network system; 2. Promoting regional linkage integration and handling good regional work It can be complemented and independent; thirdly, to implement the rational development of the waterfront area to realize the organic integration of "mountain, water, continent and city"; (4) the government of provinces and cities should provide continuous policy support.
