摘要

针对水质评价中指标个数过多

未考虑各评价指标之间的联系

以及不确定性水质评价计算方法原理深奥、计算复杂等缺点

在因子分析法的基础上

提出基于因子分析的综合指标评价法.该方法既具有因子分析的特点

同时通过综合指标的求解又能够对评价样本进行排序和分级

还能对水质样本的污染状况及主要污染物种类进行分析.经过检验表明:该方法能正确进行水质评价.由太子河辽阳段的实例研究证明:该方法直观、计算简便

是一种水质评价的有效方法.

Abstract

Numerous disadvantages were found in the existing water quality evaluation method

such as too many indices needed

among which the relationship being neglected

the abstruseness in theory and complexity in calculation evaluating the water with uncertainty model.Based on the factor analysis method

a comprehensive index evaluation method was proposed.With this method

the evaluation samples were sorted and classed through the computing of the comprehensive index and the pollution condition and main pollutants were analyzed.The proposed method had been successfully used in the water quality evaluation of Taize River in Liaoyang region

which proved the effectiveness of this direct method featuring simple computing process.
