Remote sensing and GIS techniques were used to extract the digital coastlines from the Landsat MSS/TM/ETM+ images obtained from 1973 to 2012, and to analyze the shoreline and reclamation area change of the Jiangsu coast. The remarkable erosion section is located in the abandoned Yellow River Delta, north to the mouth of the New Huaihe River, south to Shuangyang Port, with a length of 79.05 km, accounting for 8% of the total length of the Jiangsu coast. The main accretion section is centered in Jianggang Port, north to the mouth of the Yunliang River, south to Xinzhong Port, with a length of 715.50 km, accounting for 72% of the total length of the coast. The stable and accreting sections occur alternately in the rest of the coast. The maximum erosion rate is -23.37±11.92 m/a, occurring at the south side of the mouth of the abandoned Yellow River. The maximum accretion rate is 445.37± 66.80m/a, occurring at the south side of the mouth of the Sheyang River. Reclamation is the main factor affecting the shoreline change along the Jiangsu coast. In general, a coastal area of about 1912.4 km2 was reclaimed during the last 40 years from 1973 to 2012. The reclamation peak was found around 1980, then the reclamation rate reduced obviously, and reclamation activities have been reactivated since the 1990s.
