Abstratc: As an important spatial, material and environmental resource, tidal flat imposed wetland is expected to be kept harmonious balance between utilization and protection. Concept of tidal flat is declared and its spatial range is verified and the tidal flat of Shanghai area in the Changjiang Estuary is made as a case study in this paper. Fundamental features, responsibility to the discharge changes of water and sediment transported by the Changjiang River, intensity of exploitation and needs of wetland protection are discussed. Present dynamic processes and change tendency of different types of tidal flat are illuminated in detail. Favorable regulations are proposed for the reasonable exploitation, dynamic protection and ecosystem restoration of each individual tidal flat and imposed wetland. Some suggestions are proposed to make a further study about the sustainable spatial resource exploitation of offshore in Shanghai area.
