Two Landsat TM images(obtained in 2000 and 2006 respectively) were interpreted as basic information sources.The basic data of coastal wetland were obtained with the application of remote sensing and GIS-technique.The index reflecting the special structure and the heterogeneity of landscape pattern were selected by the ecological principle of landscape pattern.Those indexes were used to analysis the dynamic change of wetlands in Dalian.The result showed that the average fractal dimension index,fragment index and predominance index increased,but landscape diversity index decreased;and the area of wetlands in Dalian decreased 97.62 km2 in the past six years.The change of wetland landscape pattern was a result of the expanding of industrial zone and development of the large-scale feeding.Human activity was the main driving force for the landscape change.
