| 摘 要： | 通过Noy－Meir分离法和PCA排序分析，把火地塘林区油松天然林的优势灌木划分为照山白、绿叶胡枝子、粉背黄栌、华北绣线菊等4个生态种组；据此将油松群系划分为3个群丛组。绿叶胡枝子—油松林和黄栌—油松林这两个群丛组多为单层同世代异龄林，其演替趋向为松栎混交林；照山白十六道木—油松林群丛组为复层多世代异龄林，是相对稳定的以油松为优势的群落。

| Abstract: | Dorminant brushes of natural forest of Chinese pine (Pinus tabulaeformis) at Huodi-tang forest region could be classified into 4 ecospecies groups of Rhndndendron micranthum, Les-pedeza bue, Cotinus coggigria var. glaucophylla and Spiraea frishiana by Noy-Meir separation method and PCA ordination. The Chinese pine formation could be divided into 3 association groups of L. bue-P. tabulaeformis forest, C. coggieria var. glaucophylla - P. tabulaefomisforest and R. micranthum Abelia biflora - P. tabulaeformis forest, of which the first and the second ones were uneven-aged forest with one generation and one layer mostly and their succes-sion tendency was mixed forest between pine and oak, the third one however was uneven-aged forest with many gencrations and multilayer that was a relative stable community in which Chi-nese pine was dominant |
