摘要
为研究物元可拓法在地下水水质评价中的应用,首先对物元可拓法进行了介绍,再以北京市某地区地下水为研究对象,进行了水质综合评价,细化了水质评价标准,使评价结果更准确;利用关联度函数及权重系数等手段,排除了人为的干预,使评价结果比较客观的反映了地下水水质总体状况。经验证,模型评价符合当地实际情况。研究表明:利用物元模型对区域水资源状况进行综合评判具有客观、真实性。
In order to research the application of matter -element extension method in the evaluation of groundwater quality ,the paper first introduced the method and then took the groundwater in a region of Beijing as research object .It conducted the comprehensive evaluation of water quality and detailed the e-valuation standard of water quality , which made the evaluation result more accurate .The paper used the means of interrelatedness function and weighting factor method in order to exclude human intervention , made the result objectively reflect overall condition of groundwater quality .The evaluation accords with the local actual situation .The result indicated that the evaluation of region water resources situation by matter-element extension model is objective and tru .
