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,利用物元可拓法对建三江垦区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。
The basic theory and calculating process of Matter-Element Extension was discussed , ground water samples , which are in the section of cultivating plants in Jian Sanjiang, 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 Extension had been introduced in a great deal of field because of its impersonality, easy to calculate, well result etc.
