| 中文摘要: |
| 为了探讨露天开采矿山的土地复垦适宜性方向和主要限制因素,以登封某铝土矿为研究区,选取合适的评价因子,建立适宜性评价指标体系,采用极限条件法对研究区损毁土地进行适宜性评价,得出研究区不同损毁单元的适宜性方向和适宜性等级,并对不同适宜性方向的主要限制因素进行分析,提出针对性的改良措施,提高评价单元的适宜性等级。评价结果表明,露天采场台阶和边坡、排土场台阶和边坡适宜复垦为林草地,排土场顶部平台和工业场地可复垦为耕地或林草地,露天采场坑底可复垦为坑塘水面。研究工作可为露天开采矿山的土地复垦提供一些参考。 |
| 英文摘要: |
| In order to explore the suitability direction and main limiting factors of land reclamation in open-pit mining, took a certain bauxite mine in Dengfeng as research area, select appropriate evaluation factors, establish a suitability evaluation index system, and use the limit condition method to evaluate the suitability of damaged land in study area. The suitability evaluation is carried out to obtain the suitability direction and suitability grade of different damaged units in the study area, and the main limiting factors of different suitability directions are analyzed, and targeted improvement measures are proposed to improve the suitability grade of the evaluation unit. The evaluation results show that the steps and slopes of the open pit, the steps and slopes of the dumping site are suitable for reclamation into forest or grassland, the top platform of the dumping site and the industrial site can be reclaimed into cultivated land, forest or grassland, and the bottom of the open pit can be reclaimed into pond. The conclusions can provide a certain reference for the land reclamation of open-pit mining. |
