Optimization of Rural Residential Land Based on Weighted-Voronoi Diagram

Considering the micro-state of rural residential land,the appraisal index system of the rural residential land comprehensive influence is constructed to identify central village,maintaining village and minor residential area(relocation village).The central village influenced region is delimited according to their comprehensive influence to find out the location of the minor residential area by using weighted-Voronoi diagram,which is the one of spatial segmentation methods of urban geography,to maintain their original social spectrum and daily habits.
