Abstract: 　　
　　Qinghai Province is located on the northeast margin of the Tibetan Plateau. It has a complete variety of geothermal resources, especially the medium- deep level geothermal water resources are widely distributed, with broad prospects for development and utilization potential. Therefore, carrying out comprehensive research and evaluation on the distribution and potential of geothermal water resources in the whole province will provide a basis for the exploration deployment, development and utilization of geothermal resources in the province in the future. Based on the investigation of major hot springs and geothermal wells in the province, this article preliminarily explores the distribution characteristics and formation rules of geothermal water resources. Using geothermal reservoir method to calculate resource quantity and analyze the potential of major sedimentary basins and hot springs in the province. At the same time, opinions and suggestions were put forward on the development and utilization direction of geothermal resources in the province. The calculation results indicate that the province has abundant geothermal water resources. The total amount of medium- deep level geothermal water resources in Qinghai Province is estimated to be 1.4864×10²¹ J using the geothermal reservoir method, equivalent to 50.718 billion tons of standard coal. Among them, the geothermal water resources in sedimentary basins are 1.4737×10²¹ J, equivalent to 5.028 billion tons of standard coal; The hot springs resources are 1.28×10¹⁹ J, equivalent to 435 million tons of standard coal. Based on previous comprehensive research, we believe that the emergence of geothermal water in Qinghai Province is generally controlled by regional heat-controlling structures and their derived low-order secondary structures. Overall, it presents a segmented feature of "low temperature and scattered distribution in the north - high temperature in the central and eastern regions - dense distribution in the south (sparse in the north, dense in the south, and hot in the central and eastern regions)". The characteristics of geothermal water resources, such as water volume, temperature, and spatial distribution, correspond to the changes in the lithology of thermal reservoirs.
