摘　　要：根据对贵州碳酸盐建造中有代表性的地下热矿水中有关组分和水质数据即水温、矿化度、SiO_2、Ca^(2+)、SO_4^(2-)、(Ca^(2+)+SO_4^(2-))、Sr^(2+)和F^-的化学分析结果,本文进行了统计线性回归分析,指出热矿水中这些组分之间有显著的或一定的正相关关系;而且,此种相关特征在有成因联系的同一地区(如石阡地区)的相类同的赋水构造和建造中的热矿水之间表现得更为显著。根据热矿水形成的水—岩作用和成分形成,讨论了有关组分的来源、存在形式及组分对(如Sr^(2+)—SO_4^(2-))正相关特征的形成机理。指出锶型饮用天然矿泉水应是矿化度、SO_4^(2-)含量等适中的热矿水。On the basis of temperature and chemical data of the associated components, i.e. MDS, SiO2, Ca2+ , SO42- , Sr2+and F- , of the thermal mineral water in the carbonate rock formation in Guizhou, a statistical linear regression analysis has been carried out. The results show that there is a significant positive correlation between the temperature and these components, such as temperatur-SiO2, Ca2--SO42- , Ca2--F- , SO42--F- , and (Ca2+ + SO42-) -MDS, whose correlation coefficients (r) are 0. 9357, 0.8135, 0. 8404, 0. 9047, 0. 4545, 0. 4883 and 0. 4170 respectively, but the correlation of SO42--Sr2+ , F--Sr2+ ,Ca2+-SO42-and Ca2+-Sr2+is weaker. This correlation of the thermal mineral water in the similar water-stored structure and rock formarion appears to be more significantly reflected in Shiqian area of Guizhou in which its r values are respectively 0.8711, 0.9973, 0.9604, 0. 9890, 0. 9516, 0. 5074, 0. 9465 and 0. 9525. According to the water-rock interaction and the component development during production process of the thermal mineral water, the genesis mechanism of their correlation has been discussed in this paper, particularly those of the positive correlations for SO42--Sr2+. It is indicated that the origin of the component pairs are related to their source.
