Abstract: This paper tried to learn about the dynamics of the five types of coastal protection forest in Jinjiang of Fujian province from the landscape perspective. Four remote sensing images (taken in 1989,1993,2001,2008 respectively) were acquired, and the landscape thematic maps were also produced by using the techniques of Remote Sensing and Geographic Information System and field survey. Landscape Indexes were calculated by means of Fragstats,a landscape pattern analysis software. The result showed that during the years from 1989 to 2001, the area of the forests declined and patch density increased, so the fragmentation of the forest landscape was much more servere. During the years from 1993 to 2001, the fragmentation was worsened, especially the farmland shelter belts. During the years from 2001 to 2008, the landscape of the coastal protection forests was improved except the coastal shelterbelts. All those mentioned above came to the conclusion that once the coastal shelterbelts were damaged, they could hardly be restored. Thus, much attention should be paid to protection and development of coastal shelterbelts.
