摘要
福建省地热水氢氧环境同位素研究结果表明,大气降水是地下热水主要的补给来源。地热水的补给高程分布于165.5～1 853.3 m,各地区的补给高程差异明显。地热水氢氧环境同位素的分布特征显示受高程效应、蒸发效应及水-岩同位素交换反应等共同影响。矿化度大于1.0 g/L的地热水,氢氧环境同位素含量与氯离子含量、矿化度呈正相关,认为主要是海水混入的影响。
The hydrogen and oxygen environmental isotope study result proves that the atmospheric rainfall is the main source of geothermal fluid of Fujian province. The recharging elevation of geothermal fluid have been found between 165.5 to 1853.3 meter in Fujian province, and the recharging elevation is different obviously in different regions. Distribution characteristics of the hydrogen and oxygen isotopes in geothermal of Fujian province are affected by elevation effect, evaporation effect and water-rock isotope exchange reaction. The geothermal hydrogen and oxygen isotopes of Fujian with TDS>1 g/L are positively correlated with Cl^- and TDS. It is believed to be mainly influenced by seawater mixing.
