摘要: Abstract Coastal zones have the characteristics of rich biodiversity and high biological productivity. Based on TM images 1990 ETM 2000 2010, landuse in coastal zone Nantong (China) was classified as tidal salt marshes, silty beaches, shoals, aquaculture farms, construction land other types. Changes area pattern were analyzed by mapping corresponding statistical data. In 1990–2010, terrestrial increased notably land-sea demarcation line moved evidently direction ocean. Terrestrial expansion brought natural silting considerable overall trends evolutions region consistent with guidance strength development schemes 1990–2010. Despite fact that reclaiming along can increase resources, it may also cause serious damages to environmental quality ecological health. Jiangsu's development, we should be cautious about scope, speed, mode so avoid irreversible ecosystem.
