摘　　要：在确定评价空间的基础上,以水质标准中的Ⅰ级水质作为n维空间的基本点或参照点,结合权重计算每个待评单元以及水质标准中其他各级水质与"原点"的加权欧式距离,将待评断面划分为不同的水质级别,从而建立适合水质综合评价的加权欧式距离综合评价模型。用该模型对湟水河流域各断面的水质进行综合评价,计算简单,效果良好,符合实际,为水质综合评价提供了一种新的方法和思路。The weighted Euclidean distances between water quality of each unit to be evaluated and at other levels of the water standard, and the ＂original point＂ were calculated together with their weights, based on the determination of evaluation space, using Class I water quality in the water standard as the basic point or reference point of the N- dimension space, to divide the section to be evaluated into various water quality levels, establishing the weighted Euclidean distance model for comprehensive evaluation on water quality. This model was used for comprehensive evaluation on the water quality at various sections of Huangshui River with simple calculation and good results, which is practical and provides a new method and thought for the comprehensive evaluation of water quality.
