Using Stable Isotope Method to Identify Sources of Groundwater Recharge in Shetai Basin, Inner Monglia
In order to study groundwater recharge in the Shetai Basin,groundwater in shallow aquifers was investigated and sampled to analyze their environmental isotope vaules.The sources of groundwater recharge can be identified by these results and regional geological and hydrogeological conditions in this paper,and the conceptual model was inferred which indicates the regional groundwater recharge conditions.The results show that the main recharge sources of groundwater in this area is not from local precipitation but from precipitation in the surrounding mountain areas and the evaporation effect of groundwater is obvious.The recharge area of the eastern part is different from the western part in this basin,and the recharge elevation of the western part is higher than the eastern part.The evaporation effect of groundwater in the two parts is similar.
