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

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.
