Hot spring water and gases are always concomitant and the fluxes of gases released from different geothermal systems are various. As a  results of  water-rock reaction and degassing from the deep,the chemical and isotopic composition of geothermal spring gases are diverse because of different settings of the geothermal reservoir in the aspect of tectonic position, lithology and stress status. It is of significance to study the spatiotemporal changes of chemical and isotopic component of hot sprig gases and that may help us realize crust-lithosphere kinetic status. Furthermore, there will be application foreground in the monitoring or predicting earthquake and volcano activity as well as geothermal exploitation and utilization.
