摘　　要：土地复垦适宜性评价能够对损毁土地进行预测性的评价,在确定土地复垦最佳方向上具有重要作用。以赵固二矿为研究区,根据当地实际情况,筛选评价因素和构建指标体系,采用利用指数和法和极限条件法,并结合Arcgis空间分析工具进行适宜性评价,确定了宜耕、宜园和宜林这3个不同的复垦方向,合理地将损毁地划分了高度适宜、一般适宜、勉强适宜和不适宜这4个适宜性程度的等级,并分析了不同复垦方向上的勉强适宜区的评价单元的限制因素。评价结果表明,赵固二矿损毁土地比较适宜复垦为林地,可以通过改善灌排条件利用水土改良措施降低污染程度,提高适宜性程度。Land reclamation suitability evaluation has predicted evaluation on damaged land and plays an vital role in determining the best direction of land reclamation.The authors took Zhaogu No.2Mine as research area and based actual situation of the coal mine,screened evaluation factors and construction index system,used index method and limitation method by combining with the Arcgis spatial analysis tool to suitability evaluation,furthermore confirmed three different reclamation directions were suitable for forest,garden and arable land,divided the damaged areas into high appropriate,generally suitable,barely suitable and unsuitable four levels of suitability,and analyzed limited factor of the evaluation unit in the barely suitable areas by different reclamation directions.The evaluation results showed that the damaged land of Zhaogu No.2Mine was suitable for reclamation as forest land,and could improve the degree of pollution by improving the irrigation and drainage conditions and using soil and water improvement measures to improve the degree of suitability.
