摘　　要：农村居民点的现状适宜性评价是进行整治优化的基础,合理的整治范围为居民点的优化提供迁村合并的具体方案。以伊犁河谷察布查尔锡伯自治县为研究区,结合研究区实际地形特点,综合运用最小阻力模型、GIS空间分析和变异系数等方法构建了基于察县居民点的整治阻力及现状适宜性评价体系,并且将获得的察县综合累计阻力面与居民点现状适宜评价结果叠加,确定察县农村居民点整治类型,结合加权Voronoi图进行居民点的整治分区。结果表明:地势较陡且距大型水系越近的区域整治阻力越大,居民点现状适宜性越低。通过对居民点进行整治分类,对重点发展、内部改造、建议保留和迁移合并4种不同的整治分区进行初步整合,进而对农村居民点优化布局进行合理的引导,为农村居民点的整治优化提供决策支持。The status suitability evaluation of rural residential areas is the foundation of optimization for remediation.A reasonable range of remediation can provide specific solution for optimizing rural residential areas.We took Qapqal Xibe Autonomous County in Yili River Valley as the study area,combined with the actual terrain characteristics of the research area,integrated the method of the model of least resistance,GIS spatial analysis,and coefficient of variation and other methods to construct the status suitability evaluation system of residential areas renovation resistance based on the Qapqal Xibe Autonomous County,and superposed the result of integrated cumulative resistance surface and status suitability evaluation of residential areas to determine the type of residential areas renovation resistance,combined with weighted Voronoi diagram to regulate partition of residential areas.The results show that the terrain is steep and near the large river,the greater the resistance is,the lower the status suitability evaluation of residential areas is.Through the renovation and classification of residential areas,the preliminary integration of four different remediation divisions focusing on key development,internal transformation,suggestion retention and migration and consolidation was carried out,and then the reasonable optimizing layout of rural residential areas was guided,optimized layout,decision support for remediation optimization of rural residential areas was offered.
