摘　　要：为了研究庞泉沟国家级自然保护区八道沟植物群落的变化规律,采用样方法对其群落结构和物种组成进行调查,分析植物群落结构随海拔的变化规律。结果表明,植物群落组成和层次结构等随海拔的上升,表现出由多样性到单一性的变化趋势。海拔1800 m~2300 m,针叶树种(华北落叶松Larix principis-rupprechtii Mayr与云杉Picea asperata Mast)所占比例随海拔升高明显增加,阔叶树种(白桦Betula platyphylla Suk.,红桦Betula albosinensis Burk.,花楸Sorbus pohuashanensis(Hance)Hedl.,辽东栎Quercus wutaishansea Mary.,皂柳Salix wallichiana Anders.,毛榛Corylus mandshurica Maxim.等)所占比例随海拔升高呈明显减少到无。随海拔上升树种存在明显的更替现象。In order to study the change of plant community structure with elevation in Badaogou of Pangquangou national nature reserve,sample method was used to investigate the structure and species composition of the community.The results showed that the composition and hierarchical structure of plant communities showed a trend from diversity to unity as the altitude rised.From the altitude of 1800 m to 2300 m,the proportion of coniferous species(Larix principis-rupprechtii Mayr and Picea asperata Mast)increased with the increase of altitude,and the proportion of broad-leaved species(Betula platyphylla Suk.,Betula albosinensis Burk.,Sorbus pohuashanensis(Hance)Hedl.,Quercus wutaishansea Mary,Salix wallichiana Anders.,Corylus mandshurica Maxim.Etc)decreased to zero with the increase of altitude.There was a significant change in the species with rising altitude.
