摘要:

基于ArcGIS9.3平台,运用可达性分析技术,以江苏省淮安市为例,定量分析了城市功能用地可达性格局特征与演变。研究发现,城市功能用地可达性空间范围不断扩大,城市内部可达性水平变化不大,城市边缘的可达性变化较大;城市功能用地的空间分布与可达性水平关系密切,集中分布在可达性时间成本小的范围内;主要功能用地可达性空间格局演变表现出不同的特征,工业用地逐步由可达性成本小的城市核心区迁移到可达性成本相对较大的城市外围,居住用地相对均衡地分布在不同可达性时间范围内,小型公共设施用地主要分布于可达性时间成本小的城市核心区,大型公共设施用地则逐步迁移到可达性时间成本相对较大的城市外围;影响城市功能用地可达性格局及其演变的因素归纳为5个方面,包括地理环境、经济发展、交通引导、人口增长和政府调控。研究表明城市道路网可达性水平的提高,能够引导城市功能用地的空间布局,带动城市空间形态的演变。

Abstract:

Based on ArcGIS9.3 and accessibility analysis technology, this article analyses the evolution of accessibility pattern of land use for different function quantitatively in Huai′an City and comes to the conclusions: The first, with the expansion of urban space, the range of accessibility time is also expand correspondingly, the level of accessibility changed a little in the core of city but changed significantly in the edge of city, and the increase of the level of accessibility in the core city will lead the city to development concentration further, and the increase of the level of accessibility in periphery of the city will lead the urban development elements to spread. The second, there are the close relationship between spatial distribution of urban land use and the level of accessibility. The land use for main function concentrated in lower-cost accessibility time; the evolution of accessibility spatial pattern of main function land shows different characteristics; industrial land migrate gradually from lower-cost accessibility time in urban core area to higher-cost accessibility time in urban periphery; the residential land is distributed in the different accessibility time uniformly; the small public facilities land distribute in lower-cost accessibility time in urban core area mainly, but the public facilities land migrate gradually to higher-cost accessibility time in urban periphery. The third, on the basis of the results mentioned above, we summarize five factors which impact on the evolution of accessibility pattern of land use for different function, such as natural conditions, economic development, transportation guide, population growth and government regulation. The increase of accessibility level can guide the urban development elements to concentrate development; city government should take the effective measures to improve the accessibility level by planning and building the road network in the connection zone of the two city subdivision, and to guide the urban transition zone to development rapidly. Only in this way can the city subdivision turn into one city and effective use the city public resources.

Key words: land for urban functions, evolution of spatial pattern, accessibility, Huai'an City
