| 摘 要： | 本文采用极点排序技术，对火地塘林区主要乔木种群及森林群落进行了排序分析，结果表明影响本林区乔木种群及群落分布格局的两个显著的主导的生态梯度是海拔高度和坡度梯度。以乔木树种构成及其相对优势度作为分类依据，将火地塘林区原生森林植被划分为2个森林类群；5个类型组；10个类型。

| Abstract: | Main tree populations and forest communitise at Huoditang forest egion were oridnat-ed and analyzed using the method of polar ordination, the results showed that elevation and slope steepness were the two factors dominating the distribution patterns of the tree populations and the forest communities. On the basis of composition and relative dominance of the tree species the paraoriginal forest vegetation at Huoditang was classified into 2 forest groups, 5 type groups and 10 types. |
