The local surface water resources in Xiong 'an New Area are seriously scarce, mainly groundwater resources, and the dependence on external water transfer is high. It is of great significance to find out the dynamic characteristics and influencing factors of groundwater in Xiong 'an New Area to ensure the sustainable utilization of groundwater resources and water supply safety in Xiong 'an New Area. Based on the annual stratified groundwater level monitoring datum from 2000 to 2021, this paper analyzed the spatial distribution characteristics and evolution law of shallow and deep groundwater level in Xiong 'an New Area, and used random forest, numerical simulation and other methods to determine the influencing factors of groundwater dynamic changes. The results showed that : (1)Under the comprehensive influence of groundwater overexploitation control measures, the groundwater level in Xiong 'an New Area has been steadily rising since 2014. The average annual rise of shallow groundwater level is 0.11 m, and the average annual rise of deep confined water level is 0.64 m since 2017. ( 2 ) Groundwater exploitation, precipitation and ecological water supplement of rivers and lakes are the main controlling factors affecting the change of groundwater level in Xiong 'an New Area. In the past 20 years, the contribution rate of exploitation and precipitation to the change of groundwater level is 55 % and 42 % on average. In addition, large-scale ecological water replenishment has formed effective supply to groundwater resources.( 3 ) Numerical simulation analysis showed that the contribution rate of excessive precipitation to the recovery of water level in Xiong 'an New Area from 2019 to 2021 is as high as 63 %. Deducting the impact of precipitation, it is necessary to continuously and deeply promote effective measures such as river and lake ecological environment recovery and water source replacement to consolidate and maintain the achieved governance results.
