Abstract

Delimitation of town economic zones at county scale can provide a scientific decision-making basis for urban and rural development.By establishing the factors system for comprehensive evaluation of each central town,the central-strength is calculated by using principal component analysis.And the central towns influenced region is divided with help of weighted-Voronoi diagram based on the breakpoint theory,and then the town economic zones is delimitated according to the influenced region.
