摘　　要：研究目的:以空间相互作用为着眼点,结合"居住场势"评价,对重庆市长寿区农村居民点体系进行重构,以期为科学开展农村居民点规划和综合整治提供依据。研究方法:运用修正后的引力模型测算农村居民点与最近城镇之间的作用引力,从外部环境和经济发展两方面选取指标建立"居住场势"指标体系,评价农村居民点的发展实力。研究结果:(1)长寿区223个农村居民点的引力值介于0.21—52.32,运用Natural breaks方法将农村居民点划分为16个就地城镇化型农村居民点和207个非城镇化型农村居民点;(2)以207个非城镇化型农村居民点的"居住场势"值进行聚类分析,依此构建县域"中心村—基层村—迁并村"3级农村居民点体系,研究结果符合长寿区农村居民点的发展规律。研究结论:空间相互作用理论较好地揭示了城镇—农村居民点这一层次结构中各要素间的联系,是从空间结构优化这一角度拓宽了农村居民点体系重构的思路。The purpose of the study is to reconstruct rural settlement system of Changshou district of Chongqing City based on the spatial interaction analysis, and provide references for the planning and comprehensive improvement of rural settlement. Method employed is to improve gravity model for estimating the interacted gravity value between rural settlement and county towns, and establish indicator system for the ＂power of rural residential field＂ to assess the developmental strength of rural settlement over aspects such as natural environment and economic development. The results indicate that 1 ）the interacted gravity values of 223 rural settlements were between 0.21--52.32, which were classified into local urbanization type （including 16 rural settlements） and non-urbanization type （including 207 rural settlements）according to Jenks natural breaks method. 2）The 207 non-urbanization type rural settlements were divided into three types including central village, basic village and transitive village based on the ＂power of the residential field＂ with the help of hierarchical cluster analysis. The three ranks of rural settlements were more reasonable for developing. The results show that the spatial interaction theory is suitable for revealing the connection between the relevant factors of town-rural settlement, the study broaden the thinking of rural settlement system reconstruction from the viewpoint of spatial structure optimization.
