Quaternary distribution, Quaternary confined aquifer productivity, distribution of freshwater and seawater resources, confined groundwater age and renewability are further studied based on recently completed hydrogeological borehole, engineering pores and AMS 14C dating combined with previous data. The first confined aquifer productivity in Shepan tideland reclamation area of Sanmen Bay coastal zone is better, most of groundwater is fresh water. As a whole, freshwater resources of confined aquifer at Changjie Town of Ninghai County are distributed by herringbone patterns. Freshwater resources are mainly distributed in first confined aquifer at Dahu-Cheaogang of north Changjie Town, and freshwater resources are mainly distributed in second confined aquifer at Dahu-Xiayangtu of Changjie Town. The Quaternary confined aquifer ages are generally older. The groundwater ages of the first confined aquifer in Shepan tideland reclamation area are 21 642−22 012 cal a BP, the groundwater is not affected by late transgression. The groundwater ages of the second confined aquifer in Xiayangtu tideland reclamation area are of Changjie Town are 35 052−45 439 cal a BP, the groundwater in partial site is affected by late transgression. Under present unexploited conditions the condition of confined groundwater recharge is bad, the renewability of groundwater resources is not good. Therefore, the management of groundwater resources should be strengthened in emergency water source.
