通过深入分析采矿塌陷区耕地质量破损演化过程,认为采矿塌陷区耕地破损可分为可耕性破损、土壤环境破损及土壤本底质量破损;以采矿塌陷区耕地破损状况为研究对象,提出了指标选取的科学性原则、目的性原则、可行性原则以及敏感性原则,并建立了基于矿山地表移动变形规律的评价指标体系;采用专家打分法以及层次分析原理对各层指标进行了重要性排序。所得结论将矿山耕地质量研究与矿山地表移动变形规律研究联系了起来,为矿山地质环境整治以及矿山地表耕地的保护提供了有益的参考。
Through in-depth analysis of the process of soil quality damage evolution in mining subsidence area, it is considered that the cultivated land damage in mining subsidence area can be divided into arable damage, soil environment damage and soil quality damage. Taking the damaged condition of arable land in mining subsidence area as the research object, The scientific principle, the principle of purpose, the principle of feasibility and the principle of sensitivity are selected, and the evaluation index system based on the law of surface movement and deformation of mine is set up. Using the method of expert scoring and the principle of level analysis, the importance of each level is sorted. The conclusions obtained relate the study of the quality of arable land in mines with the research on the law of surface deformation and movement of mines, which provides a useful reference for the remediation of the mines and the protection of the arable land on the mines.
