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.
