Abstract We have identified groundwater recharge, runoff , drainage characteristics and dynamic variation, and provided a reliable scientific basis for the development and protection of groundwater resources. Based on the long-term observation data and collecting research data of Linhe groundwater, we analyzed the regional groundwater recharge, runoff and drainage characteristics and influencing factors. The study area belongs Hetao irrigation area and human irrigation activities accounted for 65.5% of all replenishment. Human exploitation and drains ditches or other human activities accounted for 67.7% of all excretion. In addition, we studied the changing trends of groundwater level in the study area, and concluded that dynamic changes of groundwater level were consistent with irrigation activities in irrigation district. Dynamic changes of urban groundwater level were mainly affected by human exploitation.
