Change of Landscape Pattern in Yalu-River Estuary Wetland

Abstract:

Three phases of remote sensing image data of Yalu-river estuary wetland taken respectively in 1983、1995 and 2007 were interpreted though ARCGIS software and the change of landscape pattern was analyzed with three categories of indices from the landscape pattern and landscape levels by means of using FRAGSTATS software. Results show that the 1983-2007, the research area of wetland landscape changes drastically, wetland landscape made of natural wetlands to artificial wetland, wetland fragmentation degree deepening, artificial wetland distribution area expanded. During the study period, the influence of human activities on the wetland increase and increase in area of sea aquaculture is the main cause of the yalu estuary wetland area reducing, is also one of the main reasons for the region function of wetland degradation.
