填沙路基边坡不同植物群落生态防护效应与生长动态变化分析

Analysis on the ecological protection effect and growth dynamic change of different plant communities on the sand-filled subgrade slope

高速公路边坡是高速公路生态最脆弱的部分,其防护和绿化是公路生态建设的重点。研究针对填沙路基边坡,对不同植物群落生态防护效应进行了探讨,同时分析了不同植物群落覆盖度、地上生物量、灌木生长速率的生长动态变化,最后提出了进一步研究中应注意的问题。

Highway Side Slope is the most fragile ecology area, its protection and green are the key of highway ecological construction. According to the sand-filled subgrade slope, the ecological protection effect of different plant communities was explored in this study, meanwhile, growth dynamic change of coverage, aboveground biomass and shrub growth rate for different plant communities were Analysed. At last, some problems needing attention were put forward in further study.
