摘　　要：介绍了物元可拓法的基本原理及计算步骤。在此基础上,利用物元可拓法对长春市伊通河附近地下水水样进行水质等级评价。从评价结果中看出,运用物元可拓法对地下水水质进行综合评价,排除了人为的干预,并利用关联度函数及权重系数等手段,使最终评价结果更加接近于实际情况,比较客观的反映了地下水水质总体状况。物元可拓方法由于其评价客观,计算简便,结果比较理想等优点,已经在诸多领域中得到了广泛应用。The basic theory and calculating process of Matter-Element Analysis was discussed, ground water samples, which are near the Yitong River in Changchun city, were evaluated. From the result of evaluation, the evaluation result gained from this method are more close to the real world by eliminating the human intervening, using correlated function and weight coefficient, and represent an impersonal remark of the main characteristic in groundwater quality. Matter-Element analysis had been introduced in a great deal of field because of its impersonality, easy to calculate, well result etc.
