摘要
根据贵州喀斯特地貌分布广泛 ,喀斯特森林受人为活动影响多处于退化状态的实际 ,选择退化喀斯特森林植物群落为研究对象 ,并采用主分量分析及系统聚类方法 ,将 71个退化喀斯特群落调查样地分列 6个集团 :草本群落为第Ⅰ集团 ;灌木群落为第Ⅱ、Ⅲ、Ⅳ集团 ;乔木群落为Ⅴ、Ⅵ集团 ;进一步将 6个集团划分为 16个不同群落类型。并分析两种不同生境对划分结果的影响 :中性至微碱性的土壤上生长的群落聚团为Ⅰ、Ⅲ、Ⅳ、Ⅵ ;微酸性覆盖层上的群落聚团为Ⅱ和Ⅴ。
Number classification of the degraded Karst forests was the base of study the natural restoration ecological process of the degraded Karst forests. Based on the facts that Karst geomorphology distributed widely and Karst forests were destroyed in central Guizhou, the degraded Karst forests were chosen as the research objects and 71plots were divided into 6 groups and 16 community types by PCA and cluster analysis, the relation between the results and the habitat, and the difference of spice in the two habits were analysed.
