Abstract结合GIS圈层分析与扇形分析,对成都市中心城区1995-2011年的空间扩展进行研究,揭示其土地利用的距离空间特征和各向异性特征。运用因子分析法对中心城区产业结构转换力进行评价,利用产业结构演变的城市化响应系数以及系统耦合度、协调度等指标,阐明1995-2011年间,成都中心城区城市生长与产业结构调整的协调过程。采用城市流模型,分析成都市的城市功能量、城市流强度以及城市流倾向度,定量确定成都市的主要外向功能及其对外联系情况。同时,以西部地区的重点城市西安和昆明作为参照城市,研究成都市功能地位变化。结合土地利用、产业结构与城市功能变化三部分内容,分析成都市发展的驱动因子以及城市空间结构与城市功能之间的作用机制和作用过程。 主要研究结论: (1)成都市中心城区在土地利用变化上,外向扩张与内部填充共存,各类用地演化存在各向异性。 1995-2011年间,不同土地利用类型在圈层上表现出不同的扩张特征。居住用地由外向扩张逐渐过渡为内部填充;公共设施用地随着居住用地的扩张而扩张,在居住用地的填充过程中,部分公共设施用地又转化为居住用地;工业用地在外向扩张过程中伴随着集团式发展,同时受政策引导影响逐渐搬迁至城市外围;交通用地面积则随着三环路、绕城高速的建设快速增长。此外,不同土地利用类型在不同方向的扩展强度上存在差异。 (2)成都市中心城区经济发展迅速,在发展过程中,经济密度提高促使成都市中心城区产业发展总水平提升,但不同产业的城市化响应、产业发展与城市生长协调性存在内部差异。 1995~2011年间,五城区产业结构转换力变化较大。2011年,凭借着经济和市场需求优势,锦江区的产业结构转换力优于其它各区,青羊区次之,而成华区受产业结构制约,其产业结构转换力在五区中最弱。 中心五城区不同产业发展城市化响应也存在区域差异。1995~2011年,城市经济密度是影响中心城区产业结构演变的主要因素,经济密度提高促使成都市中心城区产业发展总水平提升。人口承载力在合理范围内提高,是提高产业结构升级水平的关键。影响中心城区就业结构高级化水平的主要因素是城市非农人口密度。 中心城区产业发展与城市生长协调性的区域差异,不仅表现在人口-经济-空间城市化的耦合度、协调度的差异,还表现在人口城市化、经济城市化、空间城市化对城市化综合水平的贡献差异。成都市中心城区发展进程中,经济城市化贡献度最低。结合人口-经济耦合协调度、经济–空间耦合协调度和人口-空间耦合协调度,可将中心城区的城市化发展归纳为三类:综合协调导向型(金牛区)、双协调导向型(锦江区、成华区)、单协调导向型(青羊区、武侯区)。 (3)城市功能中,成都市的生产功能和科教文化功能较强。西部大开发政策实施促使成都市对区域经济增长的作用增强。 成都、西安和昆明的主要外向服务功能中,优势行业与劣势行业并存。西安市流通功能、科教文化功能始终较强,生产功能不断弱化。昆明市科教文化功能和管理服务功能较强,流通功能的优势逐渐降低,商贸功能不断强化。国家政策扶持对西部城市发展产生了积极的促进作用,2005年后,成都、西安对区域发展的带动作用增强,昆明带动作用减弱的趋势缓和。 (4)成都市空间结构的形成与功能演化是自然条件、土地利用、经济发展、交通优势度、政府决策等多种因素作用的结果。 自然条件是城市空间结构形成与发展的基础,土地利用是城市形态、城市功能的载体,经济发展是城市功能演化的动力,交通优势度是城市空间内、外功能区域联系的纽带,政府决策则是城市空间结构转变、城市功能演化的导向和驱动力。
Other AbstractCombined with circle analysis and sector analysis by GIS, this article studies on the spatial expansion of the central district of Chengdu during 1995-2011, and reveals its spatial features and anisotropy of land use. Using Factor Analysis, this paper evaluates the conversion of industrial structure. And with indicators such as urbanization response of industrial structure evolution, coupling coefficients and coordinating, it clarifies the coordination process of city growth and industrial restructuring in the central district of Chengdu. What’s more, the main outward features of Chengdu are quantitatively determined by urban flow model. And the status Chengdu plays in area, as well as its role of regional economic growth, is confirmed by the function amount, urban stream flow strength and urban stream flow propensity score. At the same time, evolution of city function status is researched, taking Xi'an and Kunming, two major cities in the western region as references. At the end of this paper, it is clarified that the driving factors and mechanism of the development of the central district, combined with evolution of urban land use, industrial structure and urban function. This paper obtained the following conclusions mainly: (1) In 1995-2011, outward expansion and internal padding coexistence in the evolution of urban spacial structurel in the center city of Chengdu. And evolution of land use is anisotropic. On the one hand, different land use exhibited different characteristics in the spheres expansion. Residential land expansion changed gradually from outward expansion to internal filling. Public facilities land expanded because of the expansion of residential land, and part of public facilities land converted to residential land in the filling process of the latter one. Industrial land developed in groups, and moved to the urban fringe gradually by policy guidance. Transportation land increased rapidly as the construction of beltway. On the other hand, different land use had different expansion strength on directions. (2) With regional differences, economy in the central district of Chengdu developed rapidly. Economic urbanization plays a limited role on urban development. Industrial structure conversion in five districts changed a lot from 1995 to 2011. In 2011, by virtue of the advantages of the economy and market demand, Jinjiang District had the best industrial structure conversion, and Qingyang District followed. However, subject to the constraints of industrial structure, Chenghua District had the weakest industrial structure conversion. It is different that urbanization response to different industries in the central five districts of Chengdu. In the central district of Chengdu, the density of the urban economy was the main factor affecting evolution of the industrial structure, and economic density improved the overall industries. Improvement of population carrying capacity within a reasonable range is the key to improve the industrial structure upgrading. The main factors affecting high-class employment structure was urban non-agricultural population density. Regional differences of coordination between industrial and urban growth not only performance on the coupling coordination degree of the population urbanization- economy urbanization- spatial urbanization, but also on the contribution of population urbanization, economic urbanization and spatial urbanization to comprehensive urbanization. In the development process of the central district of Chengdu, economic urbanization was least contributed to comprehensive urbanization. According to coupling coordination degrees between population urbanization and economic urbanization, economic urbanization and spatial urbanization, and population urbanization and spatial urbanization, urbanization in the central district of Chengdu was summarized as followed three categories: comprehensive coordination-oriented ( including Jinniu District), double coordination-oriented
