摘要
[目的]对河北省西柏坡高速公路4种不同边坡类型进行调查,旨在选择合适的边坡植被恢复技术。[方法]通过随机取样调查进行不同边坡群落组成结构分析。[结果]4种边坡类型的物种多样性差异显著。自然恢复土质边坡植被盖度最低,自然恢复石质边坡的物种多样性最差,人工恢复生态袋技术边坡的物种多样性和植被盖度最高。[结论]人工恢复生态袋技术和挂网喷播技术对高速公路边坡复绿都有明显的改善,而生态袋技术对边坡复绿改善最为明显。
[Objective]We aimed to investigate the characteristics of vegetation community along different slopes in Xibaipo highway of Hebei Province in order to choose the optimal slope vegetation restoration technology.[Methods]A random sampling method was conducted to investigate the community composition and structure on 4different types of slopes.[Results]Species diversity showed significant differences among 4different types of slopes.The vegetation coverage on soil slope was the lowest and the species diversity in rocky slope was the least under spontaneous recovery.In contrast,the species diversity and vegetation coverage was the highest on slopes by using ecological bags vegetation recovery technique.[Conclusion]Both ecological bags recovery and net-suspended spray seeding techniques can improve the vegetation recovery on highway slope,and ecological bags recovery is the most effective method.
