摘　　要：基于分析水化学特征分析,使用模糊综合评判法、灰色关联度分析法和聚类分析对待判水样进行判别,结果表明:不能通过简单的对比方法来准确判别出水水源,因为十四灰和十下灰水的水化学类型和离子浓度相近;不确定性数学模型判别结果正确率较高,聚类分析判别为100%,模糊综合判别和灰色关联度判别为95.2%。Based on the analysis of hydrogeochemical characteristics and the use of the six ions as discriminating factor. The simulation results were showed as follows. The method of simple comparison can not be used to accurately determine the water sources, because water chemistry types and ion concentrations of the fourteen and tenth limestone groundwater are similar, which indicates the presence of possible hydraulic connection. The accuracy rate of uncertainty mathematics method is relatively higher, the accuracy rate of cluster analysis, fuzzy comprehensive judgment and grey correlation discrimination was 100% and 95.2%.
