摘　　要：贵州省饮用天然矿泉水资源非常丰富,且类型多样。本文对贵州省饮用天然矿泉水进行采集检测工作。根据水质检测结果及其分布,贵州省饮用天然矿泉水水温变幅较大,变化于13.0℃~52.9℃之间,平均为22.2℃;pH值介于7.0~8.1之间,平均为7.4,总体呈中性水。Piper三线图显示其水化学类型以HCO_(3)(SO_(4))-Ca(Mg)为主。数理统计分析结果显示,贵州省饮用天然矿泉水阴阳离子的变异系数较大,反映出贵州省饮用天然矿泉水地下水化学组份形成与演化的因素相对复杂。贵州省饮用天然矿泉水类型分析得出,贵州省饮用天然矿泉水以单一锶型为主,二元复合型和多元复合型饮用天然矿泉水相对较少;饮用天然矿泉水锶含量等值线图显示,锶高值区主要分布于遵义市绥阳县和安顺市黔西县,而在黔东南州全区、贵阳市南部地区以及毕节市-六盘水市西部地区饮用天然矿泉水锶含量较低,未达锶型矿泉水限值。通过对全省饮用天然矿泉水锶含量等值线图的分析,探讨了贵州省锶型饮用天然矿泉水分布规律,为揭示全省锶型饮用天然矿泉水的成因规律具有一定指导意义。Guizhou province is rich in drinking natural mineral water resources,and the types are diverse.In this paper,natural mineral water for drinking in Guizhou province was collected and tested.According to the testing results and its distribution,the water temperature of natural mineral water for drinking in Guizhou province varies greatly,ranging from 13.0℃~52.9℃to an average of 22.2℃.The pH value is between 7.0 and 8.1,with an average of 7.4,and generally neutral water.The hydrochemical type of Piper three-line chart was mainly HCO_(3)(SO_(4))-Ca(Mg).The results of mathematical statistical analysis show that the variation coefficient of anions and positiveion in drinking natural mineral water in Guizhou province is relatively large,which reflects the relatively complex factors of the formation and evolution of groundwater components in drinking natural mineral water.According to the analysis of the drinking natural mineral water types in Guizhou province,the strontium type is the main type of drinking natural mineral water in Guizhou province,while the dual compound type and the multi-compound type are relatively few.The strontium content contour map of drinking natural mineral water shows that the strontium high value areas are mainly distributed in Suiyang County of Zunyi City and Qianxi County of Anshun City,while the strontium content in Qiandongnan prefecture,the southern region of Guiyang city and the western region of Bijie City and Liupanshui city is relatively low,which does not reach the limit value of strontium type mineral water.Based on the analysis of strontium content contour map of natural drinking mineral water in Guizhou province,the distribution law of strontium type drinking natural mineral water in Guizhou province was discussed,which has certain guiding significance for revealing the genetic law of strontium type drinking natural mineral water in Guizhou province.
