Viewshed ananlysis based on DEM was conducted along the shore highway of the Fuxian Lake.Additionally,present landscape characters were interpreted by Landsat 7 TM remote sensing data.And ecological restoration were planned to improve landscape quality depending on vegetation types,terrain features,distance to the highway and the visibility.Present landscape pattern was compared with the landscape planned to restore.The results showed that the degree of fragmentation degraded and connectivity between the patches improved.Visual landscape along the shore enhances with the improvement of forest coverage.
