Abstract:: Through the analysis of remote sensing data of Jiangsu Coastal Area in 1990, 2000 and 2009, land-use types across the area were gathered, and the land-use changes over the years were tracked. Based on the sets of data, the value of ecosystem services resulted from the changes were calculated. During 1990—2009, the areas of arable land, construction land and salt pan increased by 51.25 km²,446.56 km² and 95.51 km², respectively, while the areas of other land types reduced, wherein the area of unused land, water area, woodlands and wetlands reduced 288.80 km²,199.42 km²,68.07 km² and 37.03 km²,respectively. The total value of ecosystem services decreased from 17.205 billion yuan in 1990 to 16.631 billion yuan in 2009, thereinto the value of ecosystem services of arable land, construction land and salt pan increased by 18.25 million yuan, 7.38 million yuan and 1.58 million yuan, respectively. The values of ecosystem services of woodland, water area, wetlands and unused land reduced 85.96 million yuan,406.5 million yuan,91.11 million yuan and 18.03 million yuan, respectively. The results show that land use changes have the great impacts upon ecology service values. Therefore, the local governments should attach more importance to ecology when making relevant development plans, so as to optimize land use structure and make the land use pattern environment-friendly.
