Abstract: For the over exploitation of groundwater worsens the environment,the early-warning model about the ground water resource management is established.The model takes the urban area of Changchun as an example,and the geological and hy drological condition are considered in this paper.Based on the geological and hydrological conditions of the urban area of Changchun,the criteria of the water level and water quality are ascertained.According to the model,the early-warning system of the ground water resource management is programmed.And with the programme the early-warning performs for the water level and the water quality under the exploitation condition in the future or nowadays.Accordingly the reliable warrant and guar antee for the scientific management and the continuable utilization for the water resources can be offered.
