Based on GIS ,a method of consolidation mode of rural residential choice was structured . First ,using the space partitioning feature of Voronoi diagram ,it classified the current rural residential area initially ;then , considering natural environmental and socioeconomic factors , it built a index system of construction suitability evaluation of rural residential area ,and determined the rights of evaluation factors by factor analysis method ,and based on GIS spatial analysis ,it had a partition on the rural residential area according to the construction suitability ;At last ,it led the selection of residential consolidation mode , combined with the results of classification and partition . By this method ,the author studied the consolidation mode of rural residential of Yunxi ,the analysis results showed that 30 .02% of the current residential chose the urban and rural residential consolidation mode;17 .35% chose central village consolidation mode ;44 .43% chose joint construction consolidation mode in village ;8 .20% chose relocation consolidation mode .%基于GIS构建了农村居民点整理模式选择的方法．首先，利用Voronoi图空间分割的特性，将现状居民点进行初步分类；然后，综合考虑自然环境、社会经济等因素，构建农村居民点的建设适宜性评价指标体系，通过层次分析法确定了评价指标因子的权重，并基于GIS的空间分析功能，对建设适宜性进行分区；最后，结合分类与分区的结果，选择农村居民点整理模式．基于该方法，实证研究了郧西县农村居民点整理模式．结果表明，30．02％的现状居民点选择城乡一体化整理模式；17．35％的现状居民点选择中心村整理模式；44．43％的居民点选择村内合建整理模式；8．20％的居民点选择搬迁整理模式．
