Assessment on wetland ecosystem health in Daguhe Estuary

Based on an analysis of three phases of remote sensing images(1988,1997 and 2005),we obtained information on the land use change of the Daguhe estuary: the area of infield decreased,and the area of construction increased especially after 1997,and most of which came from infield.
