Study on Dynamic Change Features of Wetlands in Dongying City Based on RS

This paper sets 10 interpretation marks and conducts remote sensing interpretation on wetlands of Dongying City, according to data of TM and SPOT remote sensing image from three time phases in 1996, 2002 and 2006. Major types of wetlands in Dongying City include offshore and coastal wetlands, river wetlands, lake wetlands, swamp and swamping wetlands, etc. Results of interpretation show that, for recent ten years, areas of reed marsh wetlands, perpetual river wetlands and intertidal wetlands show an increasing trend, while areas of shallow sea wetlands, paddy field wetlands and mud flat wetlands have a decreasing trend. This provides scientific basis for protection of wetlands resources.
