摘要
物元模型是对事物特征进行数学描述的一种模型。事物的特征分为确定性的和不确定性的,采用联系数来描述水质特征的不确定性的方面,从而建立了基于联系数的水质评价物元模型,并结合水环境质量评价具体说明模型的使用方法。案例分析表明,联系数的物元模型应用于水质评价具有客观合理、应用方便、并能反映水质变化的动态性的优点。
Matter-element analysis is a mathematical model describing the object characteristics, which includes certain and uncertain sides. Connection number was used to express uncertain aspects of water quality feature, and the matter-element model of water quality assessment was designed based on connection number. Application of the model for water quality assessment was specifically illustrated. The case analysis shows that the model is objective and convenient, which can reflect the dynamic change of water quality.
