Abstract:Quaternary underground brine resources distributed widely along the coastal areas of the Bohai sea in Shandong province. In recent years, relevant departments vigorously developed underground brine resources, and the extent of its investigation rises gradually. But the prospecting areas scattered throughout the Bohai sea in Shandong Province. Overall research on Quaternary underground brine resources in coastal areas is less systematic and comprehensive. Based on previous datas and research achievements, research progress of brine resources has been reviewed in three aspects. Combining with the analysis on current research work, it is indicated that major research work in this area is sustainable utilization of brine resources and sustainable development of resources and environment.
