模糊综合评判在矿区地表水重金属污染评价中的应用

本文介绍了模糊综合评判法用于地表水环境质量评价的基本原理及计算步骤，并以陕西风县寺沟铅锌矿区为例，在实验室采用火焰原子吸收分光光度计法，对该矿区6个监测点的水样进行测试。在该矿区地表水分析测试资料的基础上，采用模糊综合评判法对地表水环境质量的现状进行评价。结果表明，基于模糊综合评判的地表水重金属污染评价方法能较完整地反映地表水环境质量污染程度，是一种实用而准确的评价方法，且易于推广使用。

Application of Fuzzy Comprehensive Evaluafion Method in the Mimng Area of Heavy Metal Contamination of Surface Water Evaluation

Introduced the fuzzy comprehensive evaluation method for the surface water environmental quality assessment and calculation of the basic principles of the steps,and take the Sigou lead-zinc mine area at Feng country in Shaanxi province as the example,using atomic absorption spectrophotometer in the laboratory,carries on the test to the mining area 6 test point＇ s samples.In the mining area of surface water analysis test material foundation,uses the comprehensive evaluation method to carry on the appraisal to the surface water environmental quality present situation.The results indicated the fuzzy comprehensive evaluation of heavy metal pollution assessment method can reflect completely the surface water environmental quality pollution degree,is a practical and the accurate assessment method of evaluation,and easy to promote the use.
