摘要
土地破坏程度评价对指导矿山土地复垦和生态重建具有指导意义。应用模糊数学综合评价方法对花山煤矿土地破坏程度进行评价。介绍了模糊数学评价的原理、方法和评价程序,确定了各种破坏类型土地的破坏程度评价因子、因子权重及评价等级。根据土地破坏类型,花山煤矿破坏土地可划分为两大类六单元。各单元分别建立起土地破坏程度评价的模糊评价矩阵,最终评价得出花山煤矿土地破坏程度综合评价结果为:江边排矸场为重度破坏,C区排矸场为中度破坏,地表塌陷区、水泥厂排矸场、金塘湾排矸场、沿江沟排矸场为轻度破坏。
The evaluation on the degree of destructed land in sea of mining is of important sense to guide land reclamationand ecological reconstruction. Applying for method of fuzzy mathematics comprehensive evaluation, this paper has evaluated the degree of destructed land in area of Huashan Coal Mine. It introduces the principle of evaluation, method of evaluation and procedure of evaluation about fuzzy mathematics, it also determines the evaluation factors, factors weight coefficients and evaluation standards which suit to evaluate the destructing degree of different kinds of mined soil. Based on types of ruined soil, two types and six units have been divided in Huashan Coal Mine. The fuzzy matrix is established on every evaluation unit. In the end, the comprehensive evaluation on the degree of destructed land shows that the coal-gangue mountain named Jiangbian was destructed very serious, the coalgangue mountain named C-qu was destructed relatively serious, the subsiding land and the coal-gangue mountain, named Shuinichang, Jingtangwan and Yanjianggou, were destructed lightly serious.
