中文摘要：

将生态位态势理论应用于农村居民点布局研究，从发展水平和发展潜力两方面选取指标分别作为发展“态”和发展“势”的评价因素，构建农村居民点发展评价模型，对居民点的发展实力划分等级。然后结合加权Voronoi图，明确各发展等级居民点的搬迁去向，从而实现全镇整治分区规划。沙河子镇农村居民点的发展实力可划分为高、中、低和不适宜发展4个等级；农村居民点整体发展较好，高、中发展实力级的居民点用地面积为304．07 hm2，占全区的84．23％；具有明显的地形分异特征，其发展等级呈现由中部向南北两侧递减的趋势；全镇以农村居民点城镇化为整理重点，划分为城镇化区、优先发展区、改造发展区和控制发展区4种整治分区。结合生态位态势理论和加权Voronoi图的农村居民点合理布局研究具有较强的现实指导意义。

英文摘要：

Niche ecostate-ecorole theory is applied in the study of rural residential distribution zone ,a devel-opment evaluation model was built to evaluates the rural residential niches located in Shahezi Town and grades the developmental strength of rural residential areas on the basis of developmental state and developmental potential . Then consolidation division of rural residential areas was realized by applying weighted Voronoi diagram and spatial analysis techniques to clear relocation destinations of different developmental grades of settlements .The results indi-cate that：1 ） different development strengths of rural residential areas could be divided into four grade , namely high, medium, low and unsuitable development;2） overall, rural residential development in Shahezi Town was good,land area of rural residential areas of high and middle-class development strength was 304.07 hm2 , account-ing for about 84 .23% of rural residential areas of the region;3 ） development strengths of rural residential areas presented a apparent terrain differentiation and a decreasing trend from the middle to the north and south ;4 ） con-verting from rural residential areas into Town should be regarded as key consolidation way in Shahezi Town , and ur-ban-rural combination area , priority development area , interior remodeling area and limiting development area were carried out .The analysis also found that niche ecostate-ecorole theory and weighted Voronoi diagram are combined to analysis rational distribution of rural residential land presents a strong practical significance .
