本研究在中国乡村转型发展的动态背景下，将乡村作为一个区域系统，在乡村-乡镇层面上审视了中国南方生态脆弱山区的乡村空间重构。提出了一套基于景观安全格局构建的乡村空间重构方法，以及基于蚁群优化算法和场景模拟的乡村居民点用地扩展模型。将这些方法应用于江西省长港镇的个案区。研究结果表明，理想安全情景下研究区土地利用安全格局为3种情景中最优，居住用地面积最小，关键生态用地损失最小。该情景能够充分满足生态安全、农业生产和区域社会经济发展的土地需求。研究结果表明，该方法可为南方生态脆弱山区乡村空间重构提供技术支持。仿真结果和案例区空间分区控制策略可为当地空间规划和控制实践提供决策参考。在当代中国，有必要认识和更好地探索农村的多重功能。政府对农村空间自我更新过程的科学规划和适当控制，可以更经济地利用土地，保证提供生态福利和粮食安全等公共产品。
Against the dynamic background of Chinese rural transformation development, this study takes the countryside as a regional system, and closely examines rural spatial restructuring in an ecologically fragile mountainous area of southern China at a village-township level. It puts forward a set of methods for rural spatial restructuring based on landscape security pattern construction as well as a model of rural residential land expansion using an ant colony optimization algorithm and scenario simulation. These methods are applied to the case area of Changgang Town, Jiangxi Province. The case study results indicate that the land use security pattern of the study area under the ideal security scenario is the best scenario of three examined, with the least extent of residential land and the minimum loss of key ecological land. Moreover, this scenario can fully satisfy the land demands of ecological security, agricultural production and regional socioeconomic development. These results indicate that the method we proposed can provide technical support for rural spatial restructuring in the ecologically fragile mountainous areas of southern China. Simulation results and spatial zoning control strategies for the case area can provide decision-making references for local spatial planning and control practices. In contemporary China, it is necessary to recognize and better explore the multiple functions of the countryside. The government’s scientific planning and appropriate control of self-renewal processes of rural space can make more economical use of land, and can guarantee the provision of public goods such as ecological welfare and food security.
