Abstract: Base on the four period RS images,the forest landscape dynamic changes of different zones of Dinghu Mountain Nature Reserve were analyzed by means of GIS and RS technology. The result showed that 1) From 1979 to 2007,the dominance of the forest landscape was evident,the landscape heterogeneity and stability had a declining tendency; 2) Pine forest and shrublands had transferred into even green broadleaf forest and mixed floret; The Pine forest was transferred into no-forest types and indicated it suffered the strong impact; 3) Core zone had a weak disturbance level,and the buffer zone had the strongest level of disturbance,it conforms to the basic aim of function zone partition of nature reserve; 4) The main driving force of forest change in core zone is the succession of nature,high “AGR” ratio area focuses in the west of core zone; the disturbance was the main force to change the forest in buffer zone and transition area,the high “AGR” ratio area is in the east part.

Key words: Dinghu Mountain Nature Reserve, forest landscape, temporal and spatial dynamic
