摘要
将属性集理论及其属性综合评价方法引入灌溉水质评价 ,在研究分析和确定灌溉水质单指标属性测度的基础上 ,探讨了对单指标属性测度采用加权法求解水质综合属性测度问题。以对水质评价中普遍采用的盐浓度、渗透率、特殊离子及其毒性等 5个指标进行了示例分析计算 ,所得结果表明采用该方法评价灌溉水质的科学性和客观性。
Attribute aggregate theory was introduced and applied in irrigation water quality evaluation in this paper. Relevant problems of employing weight method to deal with single index attribute measures for comprehensive water attribute measure are discussed as well. A practical sample was analyzed and calculated with the method with four indexes (i.e., concentration of salt, rate of infiltration, special ion, and toxicity), and results showed that the method is scientific and objective for irrigation water quality evaluation.
