露天采场土地复垦适宜性评价的FAHP-Entropy赋权法

Evaluation on Suitability of Land Reclamation in Open Pit Based on FAHP-Entropy Weighting Method

评价指标体系的建立和适宜性评价方法的选取是露天采场土地复垦的主要研究内容。在选取评价指标时,添加了原始土地利用方式和周围土地利用现状等指标,优化了土壤因素方面评价指标选取方式;在此基础上,建立了基于FAHP-Entropy赋权法的露天采场土地复垦适宜性评价模型,对天生坝露天采场东采坑进行了土地复垦适宜性评价。根据评价结果和天生坝露天采场东采坑的实际情况,得出结论:天生坝露天采场东采坑平台、边坡应复垦为灌木林地,坑底应复垦为天然水坑。建立的评价指标体系和适宜性评价模型具有适用性,可为露天采场土地复垦提供技术支持。

The establishment of the evaluation index system and the selection of suitable evaluation methods are the main research contents of the land reclamation in the open pit.When selecting the evaluation index,some indexes such as the use of original land and the utilization status of the surrounding land were chosen.Besides,the selection method of the evalua- tion index in the soil was optimized.According to this,an evaluation model for the suitability of land reclamation in open pit based on FAHP-Entropy coupling weighting method was established,and the evaluation on the suitability of land reclamation in the east mining pit of the Tianshengba open pit was carried out.According to the evaluation results and the actual situation of the east mining pit in the Tianshengba open pit,it concludes that the platform and the slope of the east mining pit in the Tianshengba open pit should be shrubbery land.In addition,the bottom of the pit should be natural puddle.The evaluation in- dex system and the suitability evaluation model established own good applicability,and can provide technical support for land reclamation in open pit.
