【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]:Science designated urban space and agricultural production spatial development control boundary, is an important measure for both city development and food security. This paper takes Yingtan city as an example, the construction and development of suitability evaluation of cultivated land comprehensive quality evaluation based on GIS platform. The 2 evaluation results in urban space and space layout optimization of agricultural production based on the coordination of city development direction. Through the forecast, the scale of new construction land, basic farmland protection area of cultivated land and four countries use correction scheme and basic farmland protection in city development. Hong Xianchu step boundary make spatial decision according to the space coordinate principles, coordination and optimization of urban space and spatial layout of agricultural production. The results are as follows: Center Urban Construction Development Suitability scores from high to low, showing a city in the center the center of the "circle" of the spatial distribution of Comprehensive quality of cultivated land of high heart is mainly distributed in the western and eastern city; by analyzing the movement of the center of gravity of comprehensive construction, principle analysis of Convex Hull City expansion model, analysis of city center in northern summer Buxiang infrastructure and industrial layout, and Chi Guang Zhen Hong Tang town is the focus of the future direction of development of the city center area of cultivated land; introduction the state indexes such as basic farmland protection red scheme is divided into adjustable area and adjustable area, spatial decision scheme and the red line of cultivated land protection scheme of city development boundary can not be adjusted to adjust the layout of the district conflict City Development boundary, give priority to the protection of cultivated land. The spatial decision scheme and the protection of arable land red line City Development Zone adjustable boundary scheme the layout of conflict to adjust the red line of cultivated land protection, give priority to the development of the city.
