以重庆市义和镇、石龙镇和润溪乡为例,引入引力模型,分析不同区位村镇的城乡联系强度和资源禀赋,确定3种不同的村镇发展类型。构建包括特色指标和普适指标两类指标的居民点综合适宜性评价体系,将各镇居民点划分为重点发展型、保留改造型和迁村并点型3种类型进行空间引导和优化。为适应不同乡镇的发展定位,示范镇农村居民点的优化模式分别体现集聚扩张、内部调整和迁并整合的特征。对不同类型农村居民点优化过程和技术进行探讨,为3个示范镇的规划提供科学依据。
Taking Yihe Town, Shilong Town and Runxi Township in Chongqing as an example, a gravity model was introduced to analyze the urban-rural contact strength and resource endowment of villages and towns in different locations. Three different types of village and town development were identified. Construct the comprehensive suitability evaluation system of settlements including two kinds of indexes of special characteristics and pervasive indexes, and divide the settlements of each town into three types: key development type, retained remodeling type and relocation village, and point type to guide and optimize the space. In order to adapt to the development orientation of different villages and towns, the optimization model of rural settlements in model towns embodies the characteristics of agglomeration, expansion, internal adjustment and integration. The different types of rural settlements optimization process and technology to explore for the three model town planning provide a scientific basis.
