| 矿山生态修复是国土空间生态修复的重要组成部分，然而现有相关研究主要聚焦工程视角下的单体矿山修复项目，或是纯生态视角下的修复优先级研究，少有体现国土空间尺度下矿山生态修复的统筹决策思路。以典型的矿山城市江西省丰城市为例，综合生态安全格局下的生态本底与国土空间规划中的社会发展诉求，判定矿山中生态–社会复合效益最大化的重点投入区及其他分区，并提出不同区域的修复策略。结果表明：丰城市采矿用地面积大、分布广；具有生态重要性的矿山占比达一半，但其中需要高投入进行修复的区域仅为十分之一；位于自然恢复区与低投入修复区的矿山占比最高，印证了国土空间尺度下基于自然途径的生态修复合理性。研究补充了矿山生态修复在宏观尺度决策的不足，摈弃均匀做功的生态修复模式，根据空间差异选择区域与策略，兼具生态保护与社会发展需求的双重视角，实现矿山生态修复的综合效益最大化，也使矿山生态修复专项规划能更好地融入国土空间规划体系。 |

| Abstract: |
| Mine ecological restoration is an important part of the ecological restoration of the territorial space. The existing studies of mine restoration have focused on individual projects from the angle of engineering or restoration-first studies from a purely ecological perspective, lacking an overall decision-making strategy under the territorial spatial scale. This research cites Fengcheng, a typical mining city in Jiangxi Province, as an example, to explore the ecological and social demands based on the ecological security pattern and territorial spatial planning. By determing the key input areas and other zones to maximize the ecological-social integral benefits in the mine, this paper puts forward the strategies of mine restoration in various areas. The results show that Fengcheng has the characteristics of extensive areas and wide distribution of mine land. Although the area in this region of ecological importance accounts for nearly half of the total, the area of high inputs accounts for one tenth. The area of low inputs and the area restored by nature account for the largest, thus proving the validity of natured-based ecological restoration. The research complements the inadequacy of macro-scale decisions at mine ecological restoration, provides views of ecological protection and social requirements. It also abandons the ecological restoration mode of even work, selects different restoration strategies according to spatial heterogeneity of the mine, so as to maximize the ecological and social benefits, and to better integrate the ecological restoration planning of mine into the system of spatial planning more smoothly. |
