Application of the Mathematical Model to Water Environmental Quality Evaluation and Forecasting

本文探讨了水环境质量评价、预测的数学模型及其应用。通过相关分析,说明水质评价因子选取的合理性,用聚类分析的基本原理和方法进行水质评价;用等距节点的Newton插值方法进行水环境质量预测。并用实例说明上述方法的应用。

This paper discusses water environment quality evaluation, mathematical prediction model and its application. Through correlation analysis, we explain the rationality of the appraisal factor selection. With the utility of the basic principles and methods of cluster analysis, we carry out water quality assessment. Water quality forecast is accomplished with the introduction of Newton＇ s interpolation method. Finally a numerical example is provided to show how the proposed method works.
