Analysis of dynamic change of shallow groundwater in urban area of Beihai City
In order to understand the control effect of groundwater overexploitation in the urban area of Beihai City,master the laws of groundwater dynamic change,and better provide decision-making basis for standardization of groundwater management,based on the monthly average groundwater level data from 2018 to 2022,by use of Arc-GIS spatial analysis and water level dynamic method,analysis was made on the spatiotemporal change characteris-tics of groundwater level in the research area,and the influencing factors such as precipitation and groundwater ex-ploitation etc.The results of analysis demonstrate the groundwater in the urban area of Beihai City is mainly supple-mented by rainfall infiltration;the average rate of groundwater level change is 0.21m/a belonging to weakly rise;there is no drop funnel distribution.
