中文摘要：
通过对曲果岗泉的实地调查和水样测试,总结其水化学和氢氧同位素特征,并结合当地地质、气象、水文资料分析其发育特征和成因机制,掌握内陆高寒条件下断裂型成因泉发育规律,为合理开发利用地下水提供参考.研究表明：曲果岗泉补给源为远程高山冰雪融水和大气降水,高原隆升形成的大量断裂为地下水富集和运移提供了良好通道,地下水循环周期长,具典型断裂型成因的承压泉水特征.
英文摘要：
In order to give advices on how to efficiently develop groundwater, this study summarized the characteristics of hydrochemical and carbon-oxygen isotopic through field survey and water samples testing and analyzed its development characteristics and genetic mechanism according to its local geological, meteorological and hydrological data.It grasped the development pattern of the fracture caused springs under high-cold climate conditions on mainland.The results show that the recharge source of Quguogang spring comes from the mountain snowmelt water and atmospheric precipitation;what′s more, a large number of fractures provide good path for groundwater gathering and migration in the process of plateau uplift′s formation;moreover groundwater has a long cycle period which is the typical characteristic of artesian springs caused by fracture-type.
