摘　　要：以徐州大黄山矿区耕地质量为例,通过对历年监测点数据资料和现场调查资料的分析,揭示高潜水矿区耕地质量在采矿业和农业交替扰动下的变化特征和驱动力,为合理选择复垦方式和利用方式以保证耕地可持续利用提供理论依据.研究表明,矿区耕地在利用—破坏—复垦—再利用过程中,其质量总体经历了下降—恢复—提高的变化,其中土壤肥力指标变化速度较快但不同指标变化不平衡;土壤环境质量指标变化则缓慢,有的甚至不可逆;耕地排灌条件改善明显,水资源数量保证率提高而水资源质量有所下降.Based on the soil quality analysis over annual monitoring and field investigation data at Da Huangshan mining area in Xuzhou, an evolvement feature and its driving force was revealed under the condition of mining and farming disturbance alternatively. Reasonable land reclamation methods and sustainable land utilization are proposed. The research also shows that the soil quality experienced a variation of descend-resume-elevate process during the process of land use-land deteriorating-land reclamation-land reuse. Compare with those unbalanced soil indexes variation, soil fertility index changes quicker while soil environment quality index changes slower; some of indexes even cannot athwart; farm irrigation and drainage system improved; quantity of water resources increases but the quality goes down.
