Abstract：A new round of shoreline survey led by Ministry of Natural Resources has established the le-gal and managemental basis for the separation of land and sea,which takes the average spring tide high tide line as the boundary between land and sea.Such adjustment of coastline position has made the sea area certificate landside and the land certificate seaside more prominent,resulting in a special situation of regional spatial planning and use control.Based on sorting out these two types of problems,and in combination with relevant research and policies,in this paper,we put forward corresponding policy guidance and work suggestions according to the actual situation.We suggested to(1)accelerate the promotion of the statutory coastline and establish the annual coastline change investigation system and the five-year survey mechanism;(2)guide and control the development and protection of two sides with spatial planning;(3)define the policy of land certificate renewal for reclamation in stock;and(4)issue special documents to clarify the regional management policy of land certificate in the sea,strictly control the new reclamation,ease the ownership contradiction by new ways such as three-dimensional confirmation of rights,and explore the establishment of a voluntary exit mechanism of land certificate on the sea side.On the premise of obtaining land use approval procedures,stock land should be ap-proved once non construction land was determined by the third national land survey,and construction land should be managed once the construction land was determined.Actively exploring the mechanism underlining the linkage of disposal of stock reclamation with the total amount of new construction land indicators in the region,and implementing the requirements of development concession distance and the lower limit control of ecological space reservation were highly appreciated.
