摘　　要：398眼水源井离子指标回归分析结果表明，太原市地下水中总硬度与硫酸盐、氟化物、硝酸盐（氮）存在相关性。地区不同，相关情况不同．全市范围内，总硬度与硫酸盐呈正相关，与氯化物无显著相关性。分地区看，情况恰好相反。本次研究结果表明，总硬度与氟化物显著负相关。文中提供的多元回归方程可进行有关预测。Multiple regression analysis of ionic indexes of 398 wells revealed that the total hardness is associated with sulfate,chloride, fluoride and nitrate. The correlations are different in the different districts of the city. The total hardness is highly and positively associated with sulfate, while the association between total hardness and chloride is statistically insignifican in the area of whole city. The result of different districts of city is opposite to that in the area of whole city, however. This study revealed that total hardness is highly associated with flouride negatively. The multipel regression equations provided in this article can be used as predictors.
