摘要
随着全球对铁矿石资源需求的增加,铁矿石开采活动日益频繁,导致了土地破坏和生态环境恶化。为实现矿山可持续发展,土地复垦适宜性评价已成为矿山生态环境治理与恢复的重要评价手段之一。针对山西省怀仁市A铁矿山的土地复垦适宜性进行了评价。通过构建包含土壤侵蚀能力、地形坡度、土壤结构、有效土层厚度、排水条件和土壤有机质质量分数6项关键指标的评价体系,运用极限条件法开展土地复垦潜力评估,得出土地复垦适宜性等级,为后续土地复垦工作和矿山可持续发展提供科学依据。
In the context of the escalating global demand for iron ore,the frequency of iron ore mining activities has been on the rise,resulting in land degradation and ecological environment deterioration.To achieve sustainable development of mines,the evaluation of land reclamation suitability has emerged as a pivotal tool for mine ecological environment management and restoration.The land reclamation suitability for Iron Mine A in Huairen City of Shanxi Province was systematically evaluated.An evaluation framework comprising six key indicators-soil erosion potential,topographic gradient,soil texture and structure,effective soil depth,drainage capacity,and mass fraction of soil organic matter was established.The limit condition method was applied to assess the potential for land reclamation,thereby determining the suitability classification,providing a scientific basis for the subsequent reclamation work and sustainable development of mines.
