Numerical Simulation and Rational Use of Groundwater in Beijing Daxing

In order to promoting the reasonable utilization of groundwater in Daxing district, the groundwater level dynamic process was simulated by generalizing hydrogeological conditions and constructing groundwater numerical simulation model. The results shows that the main affecting factors of groundwater level in the Daxing area are exploitation and precipitation recharge. Some groundwater exploiting measures are recommended according to the simulation result.
