Research on Resource Potential of Jinan Monoclinic Karst Groundwater System

摘要

Through the analysis on the geological structure of Jinan monoclinic karst groundwater system, the growth characteristics of aquifer, change regulation of groundwater level, combined the change of water level, groundwater exploitation quantity and atmospheric precipitation, the paper concludes that the spring discharge of the four spring groups is concluded by water level in urban, and has closely relationship with precipitation and exploitation quantity, also can be used to evaluate the resource potential of Jinan monoclinic karst groundwater system. In the restrain of ecological water level, the maximum allowable exploitation quantity should be 29.43× 10~4m~3/d and 30.94×10~4m~3/d when the spring level is 27.5m and 27.0m.. This is almost equal to the present exploitation quantity, so it hasn't the ability to increase exploitation quantity. If adopt the measures of recharge augmenting, the maximum exploitation quantity will be about 40×10~4m~3/d.
