| 摘 要： | 科学划定城镇空间和农业生产空间的空间开发管制边界,是兼顾城市发展与粮食安全的重要举措.该文以鹰潭市中心城区为例,借助GIS平台进行建设开发适宜性评价和耕地综合质量评价.基于2个评价结果开展城镇空间和农业生产空间协调优化布局研究.通过城市发展方向预测、新增建设用地规模、基本农田保护面积和耕地国家利用等四方面修正,形成城市开发边界和基本农田保护红线初步方案.根据空间矛盾协调原则做出空间决策,优化协调城镇空间和农业生产空间布局.研究结果为:中心城区建设开发适宜性分值由高到低呈现出以中心城区中心为圆心的“圈层”式的空间分布,中心城区耕地综合质量高的耕地主要分布在西部和东部;综合建设用地重心移动分析、凸壳原理分析城市扩张模式、基础设施与产业布局分析得出中心城区北部的夏埠乡、志光镇和鸿塘镇是中心城区未来发展的重点方向;引入耕地国家利用等指标,将基本农田保护红线方案划分为可调区和不可调区,城市开发边界方案与耕地保护红线方案不可调区布局冲突的空间决策为调整城市开发边界,优先保障耕地.城市开发边界方案与耕地保护红线方案可调区布局冲突的空间决策为调整耕地保护红线,优先保障城市发展.

| Abstract: | Abstract: The scientific delineation of urban space and agricultural production space restriction boundaries is an important measure for the development of city and food security. The urban growth boundary needs to be set to control the urban space sprawl. The farmland accounted for a large proportion of agricultural production space, the prime farmland protection boundary is established to protect the agricultural space. In the year of 2014, the Yingtan City was chosen by the Chinese government as the pilot city to lunch the multi-plan integration project, this project makes the Yingtan City become a perfect place to analyze the reasons that cause the spatial layout contradictions between the urban space and agricultural space, and to seek measures to solve the spatial layout contradictions. In this paper, we took the central district in Yingtan City as an example, and built the layout optimization of urban space and agricultural production space on the basis of construction suitability evaluation and comprehensive farmland quality evaluation on the GIS platform. Through the correction form the city development direction prediction, new construction land scale, the prime farmland protection scale, and farmland utility grade, the preliminary scheme of urban growth boundary and prime farmland protection boundary were generated. The overlay analysis process was applied on the GIS platform to diagnose the contradiction area between the preliminary schemes of urban growth boundary and the prime farmland protection boundary. The urban growth boundary and the prime farmland protection boundary were optimized based on the contradiction coordination principle through spatial decision-making process. The base of spatial contradiction coordination was to make the urban growth boundary and the prime farmland protection boundary of the equal importance. The results showed: (1) the construction suitability evaluation score from high to low presented the circle type of spatial distribution, the plots which had comprehensive farmland evaluation scores were distributed in the east and west part of the central district; (2) based on the analysis of construction land weight transfer, convex hull analysis of urban expansion type, and the infrastructure and industrial zone layout analysis, the north part of the central district was the future city development main direction; and (3) the preliminary scheme of prime farmland protection boundary was divided into adjustable area and regulation area based on the farmland natural utility grade. The farmland plot with lower natural utility grade than the average farmland utility grade in the research area was divided into the adjustable area. The farmland plot with higher natural utility grade than the average farmland utility grade in the research area was divided into the regulation area. The spatial decision to deal with the contradiction between the urban growth boundary preliminary scheme and the regulation area was to adjust the urban growth boundary preliminary scheme to ensure the farmland protection. The spatial decision to deal with the contradiction between the urban growth boundary preliminary scheme and the adjustable area was to adjust the prime farmland protection boundary preliminary scheme to ensure the urban development. From the research, we concluded that the spatial decision-making process could make the delineation of the urban growth boundary and the prime farmland protection boundary more objective and scientific. |
