Abstract: The categorization of different habitat types was done with principal component analysis and dynamical clustering based on parameters of the habitat . In addition , the quantitative characteristics of tree organization in Chinese fir and broad-leaved forests in different habitat types were analyzed. The results showed that : the characteristics of main parameters of habitat were distinctly different in different habitat and the dominant species and relative importance values were also different . The total number of species , species diversity , and community evenness of tree organization were different . The influence of altitude on the total number of species and on their ecological dominance was highly significant . Slope-exposure influenced the number of unit more significantly in certain degree. Altitude and slope-exposure had no influence on the ecological dominance of trees in different habitats. The protection of diversity in Chinese fir and broad-leaved mixed forest in different habitats should be emphasized.
