蓝田汤峪地区地热流体同位素水文地球化学特征及其指示意义
The Characteristics of Isotopes and Hydrogeochemistry for Geothermal Water in the Tangyu Town in Lantian County

摘要: 蓝田汤峪为秦岭山前较为典型的关中盆地地下热水的补给区，其温泉久负盛名。近年来，随着温泉旅游业的大力发展，地热水开采量逐年增加，水位持续下降，平均降深达69.16m。研究汤峪热水的补给起源及更新能力对秦岭山前乃至关中盆地地热资源的保护和可持续开发利用意义重大。笔者运用水文地球化学方法和同位素方法相结合，首次系统的对研究区地下热水的补给来源、可更新性、水岩反应的问题进行了研究，弥补了前人研究的空白或不足，对研究区地下热水的起源成因、赋存方式、热储温度等有了更进一步的认识。Abstract: Tangyu town located in the piedmont of Qinling Mountainistypicalrecharge area of geothermal water in Guanzhong basin.Its hot springs are very famous.With the rapid development of hot spring tourism in recent years, geothermal water exploitation increased year by year leads to water level drop as deep as 69.16 m onaverage.Thisaiticle focuses on the geothermal water in tangyu town and applies isotope and hydrogeochemistry methods combined with the conditions of geothermal geological structure to estimate the deep geothermal temperature,Study of the origin and regeneration of Tangyu geothermal water is of great significance to the protection and sustainable development of geothermal resources in the piedmont Qinling Mountain and Guanzhong Basin.
