基于生产-生活-生态差异的县域村镇体系发展模式研究

As the basic administrative unit of urban and rural areas, the county is not only the core carrier to implement the national "three agriculture" policy, but also a breakthrough in exploration of balanced development between urban and rural areas under the new normal. Along with the continuous advancement of urbanization, the general shortage of power of economic development of town in the county and contradiction of dramatic changes in population and land in rural areas are concerned. County-level village and town systems are experiencing not only the optimization and adjustment of production, life and ecology space, but also a fundamental change. Choosing typical cases in different regions under the influence factors of resource condition, man-land relationship and mode of production, this research analysis uncertain and variable key factors in the development of the county-level village and town system, by using evaluation system of territorial multifunction, model of residential location and evaluation system of spatial suitability. Based on characteristics of production mode, living mode and ecological background in rural areas, this project studies on the function, jobs-housing, and spatial pattern of the county-level village and town system, which relate to the production life ecosystem differences. Furthermore, by building simulation model of the development of county-level village and town system under the influence of multi variable faction, this project provide different development mode, law and mechanism of county-level village and town system with scenario combination. Through the research of the project, it is expected to establish the differential pattern of urban and rural resources allocation and provide practical guidance for the current rural planning and construction.

作为统筹城乡的基本行政单元，县域既是落实国家“三农”政策的核心载体，也是新常态下探索城乡均衡发展的突破口。随着城镇化的持续推进，县域内乡镇普遍缺乏经济发展动力、乡村人口与土地剧烈变化引发的矛盾凸显，县域村镇体系正在经历生产、生活和生态空间的优化调整乃至根本性变革。项目立足乡村地区生产方式与产业构成、生活组织与居住模式、生态本底与土地产权等特征，选择资源条件、人地关系和生产方式等因素影响下不同地域的典型区域，通过建立地域多功能性评价体系、人口区位选择模型和空间适宜性评价体系，甄别影响县域村镇体系发展的不确定性和可变性关键因素，研究生产-生活-生态“三生一体”影响下的县域村镇体系产业职能、从业-居住和空间格局发展模式。在此基础上，运用情景模拟方法构建多变量影响下的模拟模型，提出基于多情景组合的不同县域村镇体系发展模式，探究其内在机制与规律，以促进建立差异化的城乡资源配置格局，指导规划建设实践。

县域作为统筹城乡的基本行政单元，是新常态下探索城乡均衡发展的突破口。随着城镇化的不断推进，县域村镇体系正在经历生产、生活和生态空间的优化调整乃至根本性变革。.本课题以探寻城乡一体化背景下的县域村镇体系发展新范式为总体目标，从生产、生活、生态三个层面对县域村镇体系产业职能发展模式、从业-居住发展模式、空间格局发展模式等方面进行研究，剖析影响村镇体系发展的各类因素，重新审视了乡村地区生产、生活、生态的相互关联。.通过研究不同资源禀赋、发展阶段、社会经济特征影响下的县域村镇体系，提出了城乡互补、产业联动的县域村镇产业发展与职能体系；通过研究城乡均衡、便捷高效、职住平衡的县域村镇从业-居住体系，从村与城镇两部分提出了县域小城镇就业-居住空间调整策略；通过研究城市开发边界和生态保护红线划定，建立土地适应性评价模型，提出了不同类型生态空间的发展模式；通过研究城、镇、乡、村体系在社会、资源、环境等方面的新规律和生产、生活、生态各方面因素之间的互动机制，构建了小城镇宜居性评价、小城镇综合实力评价等不同类型的县域村镇体系发展评价体系。此外，在理论研究基础之上，基于各类评价和理论研究框架，针对不同类型村镇体系进行实际应用研究和行业指南编制推广。从产业发展、用地布局、设施环境等方面完成了典型村镇规划案例实践，并从产业培育、镇村联动以及统筹模式等方面探究了集体建设用地的利用方式。.通过本课题的研究，进一步完善了基于新型城镇化发展的县域村镇体系发展理论，推进了“三生一体”影响下的县域村镇体系产业职能、从业-居住和空间格局发展模式领域的研究，有助于系统研判乡村地区生产方式与产业构成、生活组织与居住模式、生态本底与土地产权等特征，甄别影响县域村镇体系发展的不确定性和可变性关键因素。对深入探究县域“三生”内在机制与规律，促进建立差异化的城乡资源配置格局，以及指导县域村镇地区规划建设实践等方面具有重要意义。
