Characteristic parameters analysis of groundwater reservoir in Jining city,Shandong province

In cone of depression areas caused by the over-exploitation of groundwater resource,the construction and planning of groundwater reservoir with the depleted aquifer space is of great significance for sustainable development and utilization of regional water resource. In this paper,the author defines the operation of water levels and reservoir capacities. Meanwhile,the spatial distribution of the reservoir capacity is analyzed by the ArcGIS. It can be concluded that the total capacity of groundwater reservoir is about 7×10⁸m³,and the utilizable capacity is more than 4.4×10⁸m³.Furthermore,the spatial distribution of reservoir capacity is different,which is caused by the specific yield and the groundwater depth.
