基于信息熵的评价模型在惠济河水质评价中的应用

Application of the Model for Water Quality Assessment Based on the Information Entropy--In the Case of Huiji River

应用基于最大熵原理的水质模糊综合评价模型 ,对开封市惠济河水质进行了综合评价 ,分析了该河水质的时空变化规律 .计算结果表明 ,该模型不仅数学物理概念清晰 ,且克服了均值化的缺点 ,同时具有计算简便实用、可靠性高的优点 ,是一种较理想的水质评价模型 .

In this paper, the model for water quality assessment based on the information entropy is introduced. A case study is conducted by using this model in the Huiji River water quality assessment. The paper also analyzes the variation law of the water quality.The result indicates that the model possesses some clear mathematic and physical conception and it is simple, practical and accurate. So this model is a more ideal one for water quality assessment.
