Abstract: The groundwater table of Taoer river fan is declining year by year.In order to rationally develop and utilize groundwater,it is necessary to analyze the dynamic characteristics of groundwater.In this paper,three methods,including groundwater dynamic analysis,contrast coefficient of variance analysis and related analysis,are used to analyze the dynamical characteristics of groundwater in the study area.The results show that the embedded depth of groundwater in the area had shown an increase trend before the year of 2010,while it showed a decrease trend after 2010;the groundwater types is infiltration-radial flow type;the groundwater depth fluctuation in the study area is big,it is significantly greater in the northeast than in other areas;there are some volatile in south and west region,too.Overall,the correlation of groundwater depth to rainfall in the study area is weak,it is significantly higher in the eastern study area than in the western study area,and only some areas show significant correlation.Overall,the underground water level dynamic in the eastern study area is more complex than that in the west and the overall water levels is falling,so it is necessary to take timely measures to control the groundwater exploration,realize surface water and groundwater joint regulation and the sustainable utilization of groundwater resources.
