根据生境因子应用主分量分析和动态聚类方法进行生境的划 分,在此基础上分析不同生境中杉阔混交林群落数量特征。结果表明:不同生境中植物群落 的主要优势种组成不一,其重要值也不同。不同生境中植物群落乔木层的物种数目、物种多 样性、群落均匀度均有较大差异。海拔对不同生境中植物群落乔木层的物种数目、物种多样 性和群落均匀度有很大影响,坡向则对个体总数和种类数量的影响较大。海拔和坡向对不同 生境中植物群落乔木层生态优势度则无明显影响。应该重视不同生境中杉阔混交林多样性的 保护。

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.
