水环境质量系数在水质模糊评价中的应用

Application of Water Quality Coefficient in Water Quality Fuzzy Assessment

根据水质评价实际情况,考虑到评价过程具有较强的模糊性,将模糊数学应用到水质评价。针对模糊数学分辨率低的问题,构建水环境质量系数,并通过实例应用,表明引入水环境质量系数,评价结果能准确反映了等级间的细微差异,提高了分辨率。

According to the practical situation of water quality evaluation, the evaluation process has relatively strong fuzziness. So the model of fuzzy mathematics in water quality is established. In view of low resolution in fuzzy mathematics model, water quality is intro-duced. The application example shows the results of using water quality coefficient can accurately reflect the difference of water quality grade, and enhance resolution. In the end, it points out the special cases and the problems which should be paid attention to in apply.
