市域空间发展类型区划分的方法探讨 ——-以江苏省仪征市为例

市域空间发展类型区划分是新时期我国从空间管治角度落实科学发展观的重要举措。 这一工作一方面是我国既有区划工作的延续，另一方面又隐含着重大的方法论创新的内在需 求，即需要由原来的基于均质区域背景的区划论升格为基于均质区域与功能区域并重的新的区划论。为此，我们专门开发了适合于空间发展类型区划分的信息系统(SPIS)，以解决不同类型因子的空间赋值以及分值迭加问题，尤其是侧重解决不同等级、不同形态的服务设施， 基于路网结构的不同类型、不同方式、不同半径的空间扩散的技术实现问题，在此基础上首次提出了空间发展类型区划分的指标判别法和指标迭加法，并以仪征为例进行了空间发展类型区划分的有效尝试。由于以自己开发的专用软件为定量分析工具，故整个区划过程公开透明，提供了从原始资料的收集、整理、分析、系统处理、多方案比较的动态分析过程，从而为空间发展类型区划分的科学性、规范性，以及有深度的定量分析提供了方法论角度的探索。

The Methods of Spatial Development Regionalization: A Case Study of Yizheng City

Spatial Development Regionalization is a great act to fulfil scientific viewpoint of development from the aspect of space control. This job is an extension of traditional regionalization, and it demands methodology innovation to upgrade the traditional regionalization theory based on equal region to a new one paying equal attention to equal region and functional region. Therefore, we design the spatial planning information system (SPIS) to solve the problem about the different types of gene evaluation and mark superposition, especially to achieve the spatial diffusion of different types and patterns and radius of public service with different scales and forms based on road network. On this basis, we put forward the index discriminance and index superposition, and make a case study of Yizheng city. Using the special procedure designed ourselves, the whole process is open and transparent. It is a dynamic process which can present the original data collection, disposal, analysis and comparison between different plans, thus it gives a sample of scientific, standard and profound method for spatial development regionalization.
