Abstract: The hydro-geochemical environment and spatial-temporal distribution of chemical elements of water for the spring regions have been analyzed,taking the Xiaotangshan spring as an example.The changes of various elements in content for the two systems,i.e.wall rock-mineral water-Ar and wall rock-mineral water-CO₂ under the effect of thermodynamic factors (pressure and temperature),were studied in combination of modelling results.On this background the changes of mineral water in chemical composition in two ways caused by future earthquake are also discussed in this paper.

摘要： 本文以小汤山温泉为例,用解剖井点的方法,对温泉区的水文地球化学环境,水中化学元素及其含量的时空分布进行了分析和研究。文章还结合室内模拟实验,着重研究了在热动力因素(压力和温度)的影响下,两个体系(围岩-矿水-Ar、围岩-矿水-CO₂)中各种元素含量的变化,并讨论了实验的实际意义及变化机理。在此基础上还探讨了未来地震可能引起小汤山矿水化学成份变化的两种可能性。
