摘要:

在经济发展新常态和建设“美丽中国”的要求下,科学合理地划定基本农田保护红线、城市开发边界和生态保护红线(“三线”)对统筹协调“生产-生活-生态”空间、高效配置土地资源、优化城市景观格局等具有积极意义。本文在对“三线”内涵解析的基础上,提出了“三线”协同划定的分析框架和协调策略,选取江苏省常州市金坛区为案例区,通过构建“生态-耕作-建设”三种利益导向的土地适宜性评价体系,分析了不同目标导向下各类土地利用适宜性程度,综合各适宜性评价结果识别土地利用冲突区,基于生态优先、集中紧凑、邻域和谐和空间识别的原则,对各类冲突区进行耦合协调,以期为“三线”划定提供新思路。研究结果表明:金坛区的生态保护红线范围主要包括西部的茅山片区、北部的天荒湖湿地以及钱资湖、长荡湖等区域,总面积260.63km2;基本农田主要分布在茅山片区及低山丘陵的东侧,中部冲积湖积圩田平原和东部的高亢平原,总面积303.57km2;城市开发边界圈定了中心城区可扩张的最大范围,总面积69.43km2

Abstract:

In the economic development of the new normal and construction of ‘Beautiful China’ requirements, delimiting the basic farmland protection red line, urban growth boundary and ecological protection red line (e.g. three lines) scientifically is needed for coordinating production-life-ecology spaces, allocating land resources and optimizing patterns of urban landscapes. Based on analysis and understanding of connotation of these three lines, we put forward an analysis framework and coordination strategy, and selects Jintan District in Changzhou, Jiangsu as a case study. By constructing an ecological-farming-construction oriented land suitability assessment system, we analyzed the suitability of land use under different target interest orientation and identified the land use conflict zone using comprehensive suitability evaluation results. The principle of ecological priority, concentration, neighborhood harmony and space recognition, therefore, can couple and coordinate each type of conflict zone and provide new ideas to delimit the three lines. We found that the ecological protection red line in Jintan District is mainly distributed in the west of Maoshan area and Tianhuang lake wetland in the north, Qianzi lake and Changdang lake area, with a total area of 260.63 km2. The basic farmland area is 303.57 km2, mainly distributed in the east side of the Maoshan area and the low hills, central alluvial lake plow plain and eastern high-Kang plain. The urban growth boundary delineates the maximum extent of the central city'’ expansion, with a total area of 69.43 km2.

Key words: basic farmland protection red line, urban growth boundary, ecological protection red line, land use conflict, coupling coordination, Jintan District in Changzhou
