Abstract: Based on the landscape ecology theory and application of GIS,this paper deals with the forest landscape pattern in Dr. Sun Yat-sen’s Mausoleum. With the electronic forest the matic map and information of forest resources survey, the area and perimeter of every forest landscape patch were computed. The total area, total perimeter and numbers of every landscape were calculated too. The forest landscape was classified into two levels. According to land use type the first level has 8 types, and the second has 7 types named dominate trees. The forest land pattern was analyzed in terms of patch density,fractal dimension, diversity, dominance etc. The results were as follows: the area of forest stand increased steadily while diversity was decreased. The hard wood forests went up but the pine forests decreased gradually.
