摘　　要：如何对矿区水资源进行合理规划利用提高水资源利用率,首先是要对矿区水质进行准确的评价,而评价方法的选择直接关系到结果的真实度。利用模糊数学综合评价法对比传统的综合评价法对老虎台矿区水质进行评价,结果表明:综合评价法界限非常严格,未能综合考虑每个水样的离子成分,极值的作用过于明显;模糊综合评价法则能综合考虑每个水样的离子成分,剔除了极值的定性作用,评价结果合理,是水质评价中值得推广的有效方法。How to reasonably plan and use water resources of the mining area for the purpose of improving utilization efficiency,truly evaluate the water quality is the first step,the different method decide validity of the result.Using Fuzzy comprehensive evaluation method compared with the comprehensive evaluation method to evaluate water quality of Laohutai mine,the result show： the boundary of comprehensive evaluation method is strict without synthetically considering every ion,the function of extreme value is too prominent.Fuzzy comprehensive evaluation method can synthetically consider every ion,eliminate extreme value effect,so the evaluation result is reasonable,which is good to utilizing and popularizing.
