Study on the Sustainable Utilization of Groundwater Resources in Hebei Plain

Hebei Plain is located in the north of Huabei Plain and it is one of the regions where the demand of water resource exceeds the supply of that greatly in current China. Because the region is short of surface water, the groundwater becomes the main supply resources. With the developing of social economy and the increasing of the population, the demand of water resource is increasing continuously. The exploitation of the groundwater exceeds the limitation of that. This paper studies the sustainable utilization of the groundwater resources in Hebei Plain by the methods such as Grey System, time series and NN. The results showed that the groundwater resources would decrease in future, and the depth of the groundwater would deepen more. The groundwater table in Shijiazhuang and Cangzhou city would decrease below sea level 30 meters by 2020.
