摘　　要：以河北省大厂县为例,应用GIS空间统计和Vonoroi图变异系数(CV)分析等方法,研究了大厂县农村居民点的空间分布特征,分析了居民点布局影响因素,并将农村居民点划分为城镇化村、中心村、迁移村和基层村4种类型。优化布局中将保留村设为需求点,迁并村设为供给点,迁并村规模设为总供给,根据两步移动搜索(2SFCA)算法计算各保留村的需求比,从而确定迁并村迁移方向和范围,最终确定了农村居民点的布局优化方案,为大厂县农村居民点的发展和布局提供科学依据,也为当前农村居民点整治和未来新农村建设提供指导和参考。This paper takes Dachang County of Hebei Province as a study area. According to the integrated application of GIS spatial statistics and the Voronoi diagram variation coefficient analysis,the distribution character and influencing factors of the rural settlements of Dachang County is analyzed. In this paper, the rural residential area is divided into four categories： urban villages, central villages, migration villages and grass-roots villages. During the layout optimization of the rural settlements, reserving villages are regarded as demand points, while villages of relocation and combination are taken as supply points, its scale of relocation and combination is set as aggregate supplies. Based on the two-step floating catchment area method （2SFCA）, the demand rate of reserving villages is calculated,and the moving directions and migration scope of villages relocation and eombina tion are also determined. The results proposed a set of scheme for the optimization of rural settlements in Dachang County, which will provide some scientific basis for the local government to make some decisions, and most importantly, it will offer some guidance and reference for the current consolidation and further prospective rural construction in the future.
