国土空间尺度下生态修复空间优先级与策略探究——以矿山用地为例

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...

Spatial Priority and Strategy of Ecological Restoration Under the Territorial Spatial Scale: A Case Study of Mine Land

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.
