摘要
为有效提高水质量综合评价水平,避免评价过程中主观性因素的影响,创新性地将熵值法引入水质量综合评价中,提出了一种基于熵值法构建水质量综合评价模型.通过熵值法计算水污染各影响指标所占权重,进而计算水质量综合评价指数,指数越高,表明水资源中所含污染物越高,反之越低.结果表明,该模型能很好地计算影响水质量各污染物指标权重及综合评价指数,计算结果直接客观,可有效判断水质.
Abstract
In order to effectively improve the comprehensive evaluation level of water quality and avoid the influence of subjective factors in the evaluation process,the entropy method is innovatively introduced into the comprehensive evaluation of water quality,and a water quality comprehensive evaluation model based on the entropy method is proposed.By using the entropy method to calculate the weights of various impact indicators of water pollution,the comprehensive evaluation index of water quality is calculated.The higher the index,the higher the pollutant content in water resources,and vice versa.The results show that the model can effectively calculate the weights and comprehensive evaluation indices of various pollutants that affect water quality,and the calculation results are direct and objective,which can effectively judge water quality.
