摘　　要：针对采煤塌陷地的特点和目前采煤塌陷区土地利用适宜性评价的不足,在初次划分的采煤塌陷区基本评价因素同质评价单元的基础上,叠置采煤引起的各种因素得到采煤塌陷地评价单元。根据评价单元之间带权重的欧氏距离,依次将面积较小而不具有实际意义的同质单元合并到相邻的最相似单元中,并以单元的面积为权重计算合并后的单元的因素评分值,得到适合于采煤塌陷区的土地利用适宜性评价单元。According to the characteristics of the coal mining subsidence area and the present land-use suitability assessment deficiencies in the coal mining subsidence area, based on the first divided homogeneous unit of evaluation factors in the coal mining subsidence area, overlay the factors caused by coal mining to obtain the evaluation unit. Based on the weighting euclidean distance between the evaluation units, turn the homogeneous unit, which is smaller and does not have practical significance, into the most similar adjacent unit, use weights of area to calculate the values about the factor of the combined unit, to get the land use suitability evaluation unit which is suitable for coal minin~ subsidence area.
