摘　　要：娘子关泉域径流-排泄区主要分布于山西省阳泉市,泉域内岩溶水是阳泉市重要的供水水源。分析评价了泉域径流-排泄区水质变化,结果显示岩溶水污染严重,主要污染物为SO2-4、总硬度、TDS。岩溶水中SO2-4的浓度来源对判别总硬度和TDS的污染源具有指示性意义,应用硫同位素(34S)计算表明采煤是岩溶水水质污染的重要原因。与2003年水质对比,地表水和岩溶水中SO2-4来自煤系硫的比重都有所增加,尤其以岩溶水排泄区的增长速率最大。The runoff-drainage area of Niangziguan spring is mainly distributed in Yangquan City, Shanxi Province. Karst water of the spring is an important water supply for the city. The results of the assess- ment of the water quality variety through runoff-drainage area show that the karst water is seriously con- taminated with the main pollutants of SO42- ,TDS and total hardness. The content of SO42- in the karst has indicative significance for pollution source discrimination of total hardness and TDS. Applications of sulfur isotope （34S） calculations show that mining is an important cause of water pollution of the karst water. The comparison of the present water quality with the water quality of 2003 demonstrates that the surface water and karst water from coal sulfur increases in the proportion of SO42- , and this increase rate is maxi mum especially in karst water of the drainage area.
