Abstract
To study the recharge mechanism of groundwater, it is necessary to determine the source of recharge water, the location of recharge area, recharge period, recharge channel and recharge rate. The study of groundwater recharge by using environmental isotopes is based on the change of isotopic composition of water with space and time. On the one hand, the isotopic composition is not affected by physical and chemical processes and remains basically unchanged during the migration from the heat source to the sampling point. Therefore, it is suitable for labeling or tracer; On the other hand, they are very sensitive to temperature change, water rock interaction, steam emission, mixed dilution of water from different sources and surface evaporation. Therefore, they are suitable as geological indicators of these processes.
