摘　　要：运用热流、地温梯度及温泉等资料,划分了黄河上游地区的地热异常区,讨论了地热与构造及地震的关系。认为断裂构造及深部热源是地热异常的主要成因;在空间上,强震分布与热异常区的分布呈相关关系。By using some information such as heat flow values,geotemperature gradient and thermal spring,the thermal anomaly zones are divided in the upstream area of the Yellow River,and the relation among geotherm,structures and earthquakes is discussed.It is thought that the geothermal anomaly is mainly caused by faulted structure and deep seated heat.The distribution of strong earthquakes are directly related with the distribution of thermal anomaly zones in the research area.

关 键 词：地温梯度 地热场 黄河上游地区 热异常区 热流数据 温泉 热流 地震
