As the interface among land, ocean and atmosphere, coastal zone has very high natural energy and biological productivity. Many people immigrate and live in coastal zone area. With the development of economy, land change and land covers in urban areas tend to change drastically over a short period of time due to rapid urbanization. The paper studied on urbanization of coastal zone area in China based on remote sensing technologies. Based on the designed research technique flow, 4 kinds of urbanization information will be rapidly extracted from remotely sensed imageries, i.e., built-up area, water area, greenness area and thermal island distribution area. Yancheng City is selected as a case for built-up area extraction experiment. Built up area in Yancheng City was extracted automatically by means of designed method from two Landsat images in 2000 and 2002 years. This experiment shows that it is feasible and effective to extract urbanization information from images via remote sensing technologies.
