Abstract: The issue of water shortage has become more evident in North China Plain. The groundwater is an important component of water resources in this area, so how to reasonably and accurately calculate groundwater recharge plays an important role in and protection of groundwater resources. In this paper, the bromide tracer method was used to study groundwater recharge in irrigation and non-irrigated areas which locate in Piedmont Aggraded Valley Plain and Median Plain of the North China Plain. The results showed that the average groundwater recharge is 126.10mm, and 0.1852 for average recharge coefficient. The recharge and recharge coefficient in irrigated areas are greater than non-irrigated areas. Meanwhile, the tracer migration depth, water content distribution, rainfall irrigation, groundwater level depth and other influencing factors were analyzed. Compared to the recharge coefficient adopted by other scholars who used the tracer to estimate groundwater recharge, the results of this study is reliable, and can provide reference and guidance to water resources analysis of the North China Plain.
