摘　　要：以供水管网微观模型为基础,综合考虑各种水质指标,采用自组织特征映射(SOM)网络和K-means算法对城市供水管网饮用水水质进行聚类分析。结果表明,水质综合评价方法可以综合考虑各种水质指标,克服了单一指标评价模型极端化、片面化的缺点,客观反映了管网中饮用水的水质状态。可见,利用SOM网络模型进行城市供水管网水质综合评价是可行的。Based on the microscopic model of water distribution system, and taking the various water quality indexes into account, the cluster analysis of drinking water quality in the water distribution system was performed by self-organizing map （SOM） and K-means algorithm. The result shows that a comprehensive water quality evaluation method can consider all kinds of water quality indexes comprehensively, overcome the defects of extremalization and one-sidedness from a single water quality model and reflect the water quality status in the water distribution system objectively. It is feasible to use the SOM network model to evaluate the water quality in urban water supply system.
