Based on a brief analysis of hydrogeological conditions in study area, the paper designed three exploiting ways such as gallery, radial well and seepage well. Through setting up three-dimensional numerical model of groundwater in the area, the reasonable yields of gallery, radial well and seepage well are 6500,0and 11800m3/d .Through contrast analysis,the simulation results suggested that seepage well has the most amount of water and the highest water supply guarantee rate and the water drawdown under the reasonable yield should be within the allowable range. The seepage well is finally selected as the exploiting way of Zhangjiachuan water source region, which has good directive function for the development and utilization of groundwater in the study area.
