Open-pit mining is an important form of coal mining in China, and its damage to the ecological environment is particularly obvious in alpine regions. The ecological restoration of alpine open-pit coal mines faces severe challenges, and its restoration effect will directly affect the ecological security of China. Meanwhile, comprehensive and system-oriented evaluation of ecological restoration effects is still insufficient in current research. In this study, we selected different quantities of assessment factors on the two scales of ecological project area and ecological impact area to evaluate the ecological restoration effect of an alpine open-pit coal mine. Then, we formed a multi-scale and multi-dimensional ecological restoration effect assessment model of the alpine open-pit coal mine and used this model to analyze the implementation effect of the ecological restoration project of the Baiyinhua No. 2 Open-pit Mine. The results show that the multi-scale and multi-dimensional ecological restoration effect assessment model of alpine open-pit coal mine proposed in this study can accurately characterize the restoration effect of open-pit coal mines in alpine regions and can also be used as a significant evaluation tool in the future ecological construction of mining areas. This study hopes the multi-scale and multi-dimensional ecological restoration effect assessment model of alpine open-pit coal mine can provide a comprehensive, systematic, and scientific evaluation method for the ecological restoration of alpine open-pit coal mines and provide a scientific basis for the ecological restoration and green development of relevant mining areas.
露天开采是中国重要的煤炭开采方式，其对生态环境的破坏在高山地区尤为明显。高山露天煤矿的生态恢复面临严峻挑战，其恢复效果将直接影响中国的生态安全。同时，当前研究对生态恢复效果的综合系统评估仍然不足。本研究在两个尺度的生态项目区和生态影响区选择了不同数量的评估因素，对高山露天煤矿的生态恢复效果进行了评价。然后，我们构建了高山露天煤矿多尺度多维度生态恢复效果评价模型，并利用该模型分析了白音花二号露天矿生态恢复工程的实施效果。结果表明，本研究提出的高山露天煤矿多尺度多维度生态恢复效果评价模型能够准确刻画高山地区露天煤矿的恢复效果，也可作为未来矿区生态建设的重要评价工具。本研究希望高山露天煤矿多尺度多维度生态恢复效果评价模型能够为高山露天煤矿的生态恢复提供全面、系统、科学的评价方法，为相关矿区的生态恢复和绿色发展提供科学依据。
