Landscape pattern change of typical wetland area of Poyang lake and its driving force

By using remote sensing images of different periods, the research can be carried out according to the landscape pattern dynamic change of wetland in Poyang Lake. It is revealed that with the influence of terrestrial and aquatic interaction and human activity the wetland landscape pattern and its change are meaningful to Poyang Lake wetland ecological protection and resource use. The result of the research has shown that the typical wetland degraded. Human activity is considered to be an essential driving force of the wetland landscape pattern dynamic change.
