According to the hydrogeological characteristics of yangling demonstration zone,by use of dynamic monitoring data of groundwater,the paper analyzed the change rule of recharge and discharge of groundwater in different hydrogeological conditions and aquifers, as well as the influence factors of dynamic change of groundwater level.It mastered the dynamic regularity of groundwater resources and put forward the scheme of development and utilization of groundwater resources.The result can provide reference for the development,utilization and dynamic analysis of groundwater in other regions.
