Abstract: At Nanjing Wuxiang Temple National Forest Park, we investigated 17 site factors of 83 forest classes. Eight dominant factors could be extracted and 8 site types could be divided based on principal component analysis and cluster analysis. The results indicated that in the forest park the main factors included soil thickness, slope direction, fall thickness and so on, and 8 site types could be classified in this forest park that included thin soil layer of medium gravel content of thick fall, medium soil layer of low gravel content of thick fall and so on. Based on the site quality, we put forth some suggestions for the stand structure regulating.
