摘　　要：本文分析宁夏黄河东岸天山海世界对流型地热资源赋存的地质条件,对研究区地热水同位素与银川盆地其他水体构成的水体同位素分布体系进行对比。研究表明,黄河断裂阻止了盆地内地下水向东部边缘运移,是一条阻水断裂。东部鄂尔多斯高原大气降水沿基岩裂隙下渗,沿着东西向导水断裂向西流动,在深部地层循环加热,在区域水头压力作用下上升,最终在黄河断裂东侧集聚,构成富水性强、水温高的地热资源。This paper analyzes the occurrence geological conditions of the convective geothermal resources in Tianshan Sea World on the east bank of the Yellow River in Ningxia,and compares the isotopic distribution system of geothermal water in the study area with that of other water bodies in Yinchuan basin.The study shows that the Yellow River fault is a water blocking fault,which prevents the groundwater from migrating to the eastern edge of the basin.The atmospheric precipitation in the eastern Ordos Plateau infiltrates along the bedrock fissures,flows westward along the east-west guide water fault,heats up in the deep stratum circularly,rises under the regional head pressure,and finally gathers in the east of the Yellow River fault,forming a geothermal resource with strong water yield and high water temperature.
