In order to examine the actuality of the groundwater resources change and the future development trend in the Jinan karst spring area and explore the approach for the sustainable management for the groundwater resources, a steady state model and an unsteady-state model are built in this paper. The results indicate that pumping groundwater in the spring collected area will affect the flow-rate of the springs directly and pumping groundwater from the groundwater resources area will affect the flow-rate of the springs indirectly by affecting the springs collected area.
