Abstract: The plain area in Hebei province is an important grain producing area and a densely populated area.However,the over exploitation of groundwater resources has seriously affected the sustainable development of regional economy and society.Based on the data from 2007to 2016in the plain area of Hebei Province,this paper analyzes the characteristics of shallow groundwater depth and storage variables,and identifies the effects of precipitation,extraction and runoff on the groundwater storage variables.The study found that the groundwater depth of shallow groundwater gradually transited to 10-20mfrom the front of the mountain to 2-5mof the coastal sea.During the year,the groundwater level varied from 5-10m in the Piedmont Plain and 1-3min the other plain areas.The characteristics of shallow groundwater storage variables in different plain areas are different,and the storage variables appeared the highest value in 2012and 2016,and the groundwater level rose obviously.Precipitation and storage variables show a significant positive correlation;the runoff and storage variables show a logarithmic relationship,but the correlation is poor;and there is no significant correlation between extraction and storage variables.
