The Tonggu Wentang hot springs and the Guqiao Tangli hot springs are discussed about the hydrological characteristics. The hot temperature is evaluated by the geothermometer methods based on the water-rock equilibrium. And analyzes the factor of hot springs through the research on the geological background. The results showed that hydrochemical types of Xiushui Kangri hot spring thermal waters are the type of HCO3-Na

and Tonggu Wentang and Tangli hot spring thermal waters are type of SO4-HCO3-Na-K that caused by the different geological background conditions. Besides

all the three hot springs are inferior to balance of water-rock by the mineral balance diagram and the Na-K-Mg triangle graphic simulation. Only the No.1 drill from Kangri hot spring is close to the balance of water-rock

and the reservoir temperature is estimated to be 100-120%℃ that is consistent with the 102-102 ℃ which calculated by the geothermometers of SiO 2.
