| 为了科学划分农村居民点类型，对不同类型农村居民点提出相应的整治措施，本研究以吉林省辉南县为例，构建生产-生活-生态空间评价指标体系，采用最小阻力模型和K-均值聚类分析划分村庄组团类型，依据改进的空间引力模型和加权Voronoi图结果，进一步在村庄组团内部划分出不同的农村居民点类型。结果表明，研究区域“三生”空间综合阻力值分布差异性特征显著，总体呈东高西低趋势，按照综合阻力值大小分为最小、较小、中度、较大、最大5个阻力区。基于综合阻力分区结果与聚类结果划分出4种村庄组团类型：集聚提升类村庄47个，总面积为1.243×107 m2；城郊融合类村庄35个，总面积为7.169×106 m2；特色保护类村庄41个，总面积为1.252×107 m2；稳定改善类村庄18个，总面积为4.201×106 m2。根据村庄组团内部相对引力值关系和每个农村居民点实际的功能辐射范围，进一步在村庄组团内部划分出重点建设型、一般建设型、迁移合并型3种农村居民点类型，并在此基础上对农村居民点布局优化提出相应的整治策略。研究表明，生产-生活-生态空间评价指标体系可以较好地反映外界因素组合对辉南县农村居民点布局的影响，基于最小阻力模型等多种空间分析方法划分村庄组团及其内部组合特征，能够科学划分农村居民点类型，从而对不同农村居民点类型提出相应的治理措施，制定符合当地发展的策略。 |

| To scientifically categorize the types of rural settlements, corresponding rectification measures were proposed for different types of rural settlements. Taking Huinan County, Jilin Province as a case study, a spatial evaluation index system of production-life-ecology was constructed to categorize the types of village clusters by analyzing the minimum resistance model and K-means clustering results, and further classified different rural settlement types within the village clusters according to the improved spatial gravity model and weighted Voronoi diagram. According to the size of the comprehensive resistance value, it was divided into five resistance zones： minimum, small, medium, large, and maximum, and four village group types were established based on the comprehensive resistance zoning results and clustering results. The cluster promotion included 47 villages with a total scale of 1.243×107 m2, and the suburban integration included 35 villages with a total scale of 7.169×106 m2. The featured protection included 41 villages with a total scale of 1.252×107 m2, and the stable improvement included 18 villages with a total scale of 4.201×106 m2. According to the relative gravitational value relationship within the village group and the actual functional radiation range of each rural settlement, the direction of migration and merger of rural settlements were determined, and rural settlements were further divided into three types within the village group：key construction, general construction, and migration and merger. Corresponding rectification strategies were proposed for the optimization of the layout of rural settlements. The production-life-ecology spatial evaluation index system can better reflect the influence of the combination of external factors on the layout of rural settlements in Huinan County. Based on various spatial analysis methods, such as the least resistance model, the characteristics of village groups and their internal combinations were categorized, the types of rural settlements were scientifically classified, corresponding management measures were proposed for different types of rural settlements, and strategies in line with local developments were developed. |
