Abstract: Based on the research in Shangrila County, Yunnan province of China,the major factors of forestry division in Shangrila were extracted,and the indicator system of Shangrila forestry division was established. The indicators were extracted with the spatial analysis,and the forestry division method of integrated modeling was processed. The method was taken through Principal Components Analysis,building the integrated model,Discriminate Analysis,seeking the ideal number of divisions and eliminating the scrappy polygons. The outcome showed that the method can reflect the present situation of the forestry development. The relative dominant subdivisions were distinguished reasonably,and a specific direction in forestry development was given. According to the statistics of the subdivisions,the relative dominant subdivisions were showed obviously.

Key words: forest division, PCA, discriminative analysis, Shangrila
