Application of remote sensing technology in Cao Feidian coastal zone monitoring

Using 5 periods´ remote sensing images covering 20 years from 1985 to 2008 of Cao Feidian, this paper extracted the coastline and the wetlands from different years utilizing different methods and techniques of data image processing and visual interpretation based on the characteristic of each RS image. The paper analyzed the law of the coastline and the wetlands changes in both spatial and temporal aspects, and then discussed the major influential factor to the changes by analyzing natural and artificial factors. The results indicated that the total coastline and the artificial coastline increased, while the natural seashore disappeared and wetlands slight increase in the 1985-2008.
