초록
Human activity has been the major threat to wetlands. Agriculture, industrial development,and urban and suburban sprawl have caused the greatest losses of coastal wetlands. In fact,riceland agriculture, because of the flooding that goes with it, provides some additionalwetland habitat not otherwise available. The biggest current source of loss for freshwatercoastal wetlands is from urban sprawl.In this study, spatial analysis method such as landscape index were applied to Sihwa area inAnsan city. The SMA (Spectral Mixture Analysis) method using Landsat image showed thechange distribution of wetland vegetation from 1996 to 2004. The southern part of Sihwawetland have been changed with Suda japonicaof 24% and reed vegetation of 34% on coastalwetland which were covered with tidal flat.
