摘　　要：土地复垦适宜性评价是开展土地复垦的基础性工作,而不同评价方法的选取将影响土地复垦适宜性评价结果的准确性和客观性,进而影响土地复垦的决策工作。作者对现有的极限条件法、指数和法、可拓法、模糊综合评价法和人工神经网络评价法等适宜性评价方法进行了对比分析,并在此基础上,提出了一种新的极限综合评价法,并将该方法应用于鹤壁市第八煤矿的土地复垦工作中,取得了良好的效果。该方法比传统的评价方法有更好的适用性,且操作简单,得出的评价结果更加科学。The suitability evaluation of land reclamation in mining area has multiple significance for land reclamation,and different methods selected will affect the accuracy and objectivity of suitability evaluation results,thereby will affect decision-making of land reclamation.In the paper,five basic methods：extreme condition method,sum of index method,extension method,fuzzy comprehensive assessment method and artificial neura1 network method were discussed and analyzed,and on the basis,a comprehensive extreme condition method was developed and applied in land reclamation of Eighth Coal Mine in Hebi and good results were acquired.This evaluation method has better applicability than traditional methods,its operation is simple and evaluation results obtained will be more scientific.
