Abstract
Taking topographic map in 1970s as reference,four periods terrestrial coastlines in Zhejiang province were depicted by using TM data in 1986 and 1995,ASTER data in 2005 and HJ data in 2009.In those four years,changed coastline,increased land area and fractal dimension value were calculated.The conclusions were as follows: ① The three satellite data could meet the precise and quick requirements of rapid coastline change monitoring;② Zhejiang terrestrial coastline fast expanded forward ocean,205.24 km2 newly increased land from 1986 to 1995,319.85 km2 from 1995 to 2005,484.75 km2 from 2005 to 2009;③ The fractal dimension of coastline in Zhejiang province was relative small,which meant low level of complex,the value of fractal dimension was gradually decreased in recent two decades.
