摘要
The Yongding River groundwater system in Beijing plain is located in western Beijing. Precipitation samples of a hydrological year in Beijing plain were collected, and D and 18O components of these samples were analyzed. On such a basis, some conclusions have been reached: the hydrochemical types of groundwater in the study area are comparatively simple; the groundwater in the study area is derived mainly from infiltration of local precipitation, and is affected by different degrees of evaporation during the process; Sr and Ca elements in groundwater share a similar hydrogeochemical process; values and variation range of 87Sr/86Sr ratios are small, which implies that Sr element in groundwater comes from carbonate rock. The results obtained by the authors will provide a practical basis for further understanding the groundwater system of the study area and the water sources.
