煤矿区水环境质量现状评价研究

STUDY ON THE ACTUALITY OF WATER ENVIRONMENTAL QUALITY EVALUATION IN COAL MINE

运用灰色 聚类方 法对韩城 矿区桑树 坪煤矿 水环境质 量现 状进 行了 评价， 其评 价结 果与 模糊综合评 判大体 吻合。该 方法不仅 注意到水 质分级 界限的模 糊性， 而且 信息 利用 率和 精度 均有 较大幅度的 提高。因 此，利用 灰色聚类 进行水 环境质量 评价不 仅方法简 便，而且 结论更接 近客观实

The Grey clustering method is used to evaluate the actuality of water environmental quality in Sang Shuping coal mine. The result is compatible substantially with the fuzzy mathematics overall evaluation's. This method not only considers the fuzziness of water quality classification limit but also enhances the precision and the utilization ratio of information.Therefore,the method is convenient for water environmental quality evaluation,the conclusion is close to the reality.
