Satellite Remote Sensing Monitoring Techniques on East Dongtinghu Wetland
Using TM data and image process software Erdas8.7,the East Dongtinghu wetland's area and distribution information were obtained by methods of Spectral Angle Mapper and man-machine interactive interpretation.The dynamic changes of East Dongtinghu wetland area and its spatial distribution between 1987 and 2004 were studied by the methods of images integration,interactive visual interpretation and classification results overlay.The results showed that under the effects of vegetation succession and sediment deposition,the area of East Dongtinghu wetland shrank continuously,which caused the regional degradation of wetland to varying degrees.
