In this paper, the landscape cover, the coastline and artificial dams were extracted from Landsat 5 TM and SPOT5 images by the combination of supervised classification based on Support Vector Machine (SVM) and visual interpretation. And the influence of artificial dams on landscape structure and landscape pattern was analyzed by landscape pattern index and gradient analysis of NDVI. The results suggest that, the accuracy of landscape cover extraction met the requirements of change analysis of the landscape pattern. The artificial dams effectively prevented the backward erosion of inland area. In addition to the estuary area, the area of the tidal...
