摘要
为了更全面反映水体综合状态,本文基于单因子评价水质等级的结果,计算指标与等级的相关系数,筛选出强相关的指标.采用专家打分构造犹豫模糊水质评价初始矩阵,建立基于犹豫模糊指数熵和线性插值悲观升维的加权犹豫模糊兰氏距离测度多属性评价方法.最后,结合浙江省部分水库水质数据进行实例分析.结果表明,所提出的基于犹豫模糊集距离测度的水质综合评价方法更为合理有效.
In order to assess the overall state of water bodies,based on the results of single factor evaluation of water quality grades,the correlation coefficient between the indicators and grades is calculated,and strong correlation indicators are selected.An initial matrix of hesitation fuzzy water quality assessment is constructed using expert scoring,and a weighted hesitation fuzzy Lancet distance measure multiple attribute evaluation method is established based on hesitation fuzzy exponential entropy and linear interpolation pessimistic dimensionality.Finally,an example analysis is conducted based on the water quality data of some reservoirs in Zhejiang Province.The results show that the proposed method for overall assessment of water quality is more reasonable and efficient.
