Abstract:

This paper studies the spatial distribution of rural residential land of the town of Yihe, Shilong and Runxi in Chongqing, and optimizes the spatial pattern based upon their urban-rural linkages. According to the intensity of urban-rural linkage derived from gravity model, the three towns are categorized into three types of rural areas, namely industrial expansion area at urban fringe, ecological conservation districts in the suburbs and agricultural districts in remote mountainous areas. The authors construct an evaluation system, consisting of general index and featured index. Every plaque of rural residential land is classified as developing, adjusting or removing according to the result of evaluation. Three modes of optimization are concluded from the case study. The proposed method of spatial optimization focuses on the diversity of rural development and deals with challenges for rural areas in contemporary China. It contributes to a balanced urban-rural development and provides scientific evidence for the New-Type urbanization plan.

Key words: rural residential land, layout optimization, urban-rural linkage, gravity model, suitability evaluation, neighborhood effect, Chongqing

摘要：

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。
