| 摘 要： | 在庐山自然保护区沿山顶公路和山下的环山公路调查草本外来植物的种数、盖度以及环境因子(海拔、自然度),以评估外来植物分布现状。结果表明:环山公路和山顶公路路域呈现不同的外来植物分布。环山公路路域外来植物的种数、盖度显著比山顶公路路域的高;环山公路和山顶公路路域海拔差异显著,海拔是造成外来植物不同分布的主要环境因子。

| Abstract: | To estimate the difference of alien plant distribution patterns in different elevation roadsides, in summer 2010 we employed Lushan National Park in Jiangxi Province as our study site. Total coverage of alien species, number of alien plant species and environmental variables (elevation and naturalness degree) of each plot with alien plant species were calculated and analyzed. MANOVA results showed that the number and coverage of alien plant species are significantly different from roadsides peak and down the mountain. Canonical Correspondence Analysis results indicated that elevation was key environmental variable for distinct distribution patterns of alien plant species. |
