Abstract
For the limited method and study on the service area division of the regional market town system, this paper comprehensively analyzes and evaluates the different factors affecting the space service area division of the regional market town system, with AHP and comprehensive fuzzy evaluation. Those factors are concluded as generalized costs and market town attractive factor, to represent the comprehensive attraction for single market town to its space service area, after establishing service area division model based on the gravitational model, the weighted voronoi diagram and the discrete generation algorithm are introduced on the Marine GIS platform to realize the precise dynamic division of the regional market town system. At the same time, considering the regional village distribution and market town demand distribution, we can calculate the actual operation demand of each market town. Practical example shows that the proposed method is able to meet the requirements for the market town planning and can offer the reference to the decision making for administrative departments in the number, scale, location, layout and service area expanding of the market town.
