摘　　要：以贵州省变质岩区典型的剑河温泉为研究对象,从温泉所在区域地质、地热地质背景入手,分析了剑河温泉的水文地球化学和氢氧同位素特征,结果表明：温泉具有断裂（裂隙）型温泉特征,温泉的不具岩浆热源,主要是靠正常的区域大地热流量来提供热和维持,补给来源为大气降水,剑补给区的高程在1050~1150m之间,热储温度约为68.3℃,地热水循环深度约2890m。温泉的形成主要受岩性及区域性断裂控制,大气降水通过断裂破碎带向下入渗、运移,并不断被加热,至革东断层后上升,在地势低洼处出露形成温泉。This paper takes typical Jianhe Hot Spring in Guizhou metamorphic rock area as the research object,starts from the geological and geothermal background of the hot spring area and analyzes the hydrogeochemical,hydrogen and oxygen isotopes characteristics of Jianhe Hot Spring.The results show that Jianhe Hot Spring has the characteristics of fracture（fissure）Hot Spring.The hot spring has no magma heat source,so it mainly relies on the earth heat flow in normal areas to provide heat and survive.The source of replenishment is meteoric waters.The elevation of Jianhe replenishment area is between 1050 and 1150meters.The geothermal reservoir temperature is 68.3℃.The circulation depth of geothermal water is about2890 m.The formation of hot spring is mainly controlled by lithology and regional faults.Meteoric waters permeate and migrate downward through the fractured zone,gets heated continuously and rises till the Gedong Fault.They emerge in low-lying places and forms hot spring.
