基于“生态+景观+经济”模式的矿区生态修复与人居环境建设研究:以陕西省府谷县三道沟煤矿沉陷区为例

    Research on ecological restoration and human settlement environment construction in mining areas based on “ecology+landscape+economy” model: a case study of the subsidence area in Sandaogou Coal Mine, Fugu County, Shaanxi Province

    • 摘要: 煤炭高强度开采造成地表沉陷及地质灾害频发,而传统的煤矿沉陷区生态治理模式成本高、实施阻力大、生态效益差,难以实现区域生态环境与经济发展之间的平衡。当前,矿区生态修复亟需探索可行的生态修复未来模式和实施路径,通过模式创新,实现矿区生态修复效益的可持续发展。本文以陕西省府谷县三道沟煤矿沉陷区的生态修复案例为实例,围绕“现状-问题-对策-效果”的逻辑链,通过实地调研,系统分析沉陷区生态治理过程中面临的问题,对沉陷区的生态修复路径、模式与技术进行多层次剖析,并客观评价基于“生态+景观+经济”模式下的矿区生态环境治理效果。研究结果表明,三道沟煤矿沉陷区在治理实践中采取精细化分区策略,坚持以自然恢复为主,人工干预为辅的原则,重点推进林业复垦和农业复垦工程,成功建成沉陷区生态林和农田示范区,实现了该区生态系统的结构修复和功能重建,有效促进了该区自然和乡村人居环境的协同发展。本实例证明,在以“生态+景观+经济”为核心的矿区生态修复综合治理模式中,能显著提升生态效益,对同类型煤矿沉陷区的生态治理具有推广意义,可为实现矿区地质环境治理与乡村振兴战略的有机统一提供理论依据,也可为矿区生态环境的可持续发展提供技术参考和实践经验。

       

      Abstract: High intensity coal mining causes frequent land subsidence and geological disasters. However, traditional ecological governance method for mining subsidence areas faces critical challenges: high cost, significant implementation difficulties, and poor ecological outcomes. This approach consistently fails to achieve a balance between regional ecological environment and economic development. Currently, there is an urgent need to explore feasible future models and implementation paths for ecological restoration in mining areas. Through model innovation, sustainable development of ecological restoration benefits in mining areas can be achieved. This study uses the ecological restoration case of the subsidence area at Sandaogou Coal Mine in Fugu County, Shaanxi Province, focusing on the logical chain of “context-problems-solutions-outcomes”. Through field research, the problems faced in the ecological governance process of subsidence areas are systematically analyzed, and the ecological restoration paths, models, and technologies of subsidence areas are analyzed at multiple levels. The ecological environment governance effect of mining areas based on the “ecology+landscape+economy” model is objectively evaluated. The research results demonstrate that the subsidence area in Sandaogou Coal Mine implements differentiated zoning strategies during rehabilitation. Guided by the principle of prioritizing natural restoration with targeted human interventions, it focuses on advancing forestry and agricultural reclamation projects, successfully built ecological forests and agricultural demonstration areas in subsidence areas. The structural restoration and functional reconstruction of the ecosystem in the area have been achieved, effectively promoting the coordinated development of the natural and rural living environment in the area. This example proves that in the comprehensive governance model of ecological restoration in mining areas with “ecology+landscape+economy” as the core, the ecological benefits can be significantly improved, which has promotional significance for the ecological governance of similar coal mine subsidence areas. It can provide theoretical basis for the organic unity of geological environment governance and rural revitalization strategy in mining areas, and also provide technical reference and practical experience for the sustainable development of ecological environment in mining areas.
