新疆四大煤田采动生态损伤特征与生态修复研究进展

    Research progress on mining-induced ecological damage characteristics and ecological restoration in the four major coalfields of Xinjiang

    • 摘要: 煤炭开采不可避免地扰动矿区土地生态环境,亟待构建适配新疆特殊生境的生态修复理论与技术体系。通过梳理新疆四大煤田(准东煤田、吐哈煤田、伊犁煤田、库拜煤田)自然地理格局和地质采矿条件,解析了区域采动生态损伤特征,采用文献计量与案例分析方法,综述了2000—2024年新疆矿区生态修复研究进展,展望了四大煤田生态修复重点研究方向。研究结果表明:①四大煤田开采模式与生态损伤特征呈现显著空间分异:准东-吐哈荒漠戈壁矿区以露天开采为主导,高强度采剥破坏地表砾幕层结构,导致防风固沙功能衰退;伊犁绿洲矿区井工开采引发地表塌陷与地裂缝扩展,诱发耕地损毁与草场退化;库拜山地矿区采动覆岩及地表裂隙扰动浅表层生态水位,加剧岩漠化进程;②新疆矿山生态修复研究起步晚,但研发速度快,研究热点聚焦于微地形-植被协同修复、土壤重构和微生物修复技术,近年来逐渐重视荒漠戈壁矿区采动砾幕层损伤基础研究及其仿自然修复技术研发;③新疆矿山生态修复研究重点正经历从“末端治理”到“过程调控”的初步过渡和从“单要素修复”到“系统重构”的系统修复;④当前面临核心瓶颈:缺乏区域采动损伤基础理论支撑,分区生态修复目标不明,修复技术标准化与长效性不足,难以满足区域优质煤炭产能的持续释放需求。研究有助于系统了解新疆煤矿区生态修复现状,一定程度上为区域矿山生态修复规划、技术研发和标准制定提供基础。

       

      Abstract: Coal mining inevitably disturbs land ecosystems, urgently necessitating the development of ecological restoration theories and technologies tailored to Xinjiang’s unique habitats. This paper systematically examines the natural geography and geo-mining conditions of Xinjiang’s four major coalfields, analyzes regional mining-induced ecological damage characteristics, reviews ecological restoration research progress in Xinjiang mining areas (2000-2024), and proposes priority research directions for these coalfields. Key findings include: ①significant spatial heterogeneity exists in mining modes and ecological impacts. Open-pit mining in the Zhundong-Turpan-Hami desert-gobi coalfields disrupt gravel-layer structures, impairing windbreak and sand fixation capacities; underground mining in the Yili oasis coalfields induces surface subsidence and ground fissures, exacerbating cropland and grassland degradation; and fracture networks in the Kuche-Baicheng mountainous coalfields disturb shallow ecological water tables, accelerating rocky desertification. ②Despite its late inception, ecological restoration research in Xinjiang has progressed rapidly, emphasizing micro-topography-vegetation synergy, soil reconstruction, and microbial remediation, with growing attention to gravel-layer damage mechanisms and nature-inspired restoration technologies in desert-gobi mining areas. ③Research on ecological restoration in Xinjiang’s mining areas is undergoing an initial transition from “end-of-pipe treatment” to “process regulation” and from “single-element restoration” to “systemic reconstruction”. ④Critical challenges persist, including insufficient theoretical frameworks for regional mining damage, ambiguous zonal restoration objectives, and non-standardized, short-lived restoration technologies, its difficulty in meeting the sustained release demand for high-quality coal production capacity in the region. This study provides a comprehensive baseline for ecological planning, technology innovation, and standardization in Xinjiang’s coal mining areas.
