广西贺巴高速来都段石漠化边坡植被恢复和生态防护技术的应用分析

Application Analysis of Vegetation Restoration and Ecological Protection Technology in Rocky Desertification Slope at Laidu Section on Heba Expressway in Guangxi

石漠化边坡的植被恢复和生态防护是目前绿色公路建设的热点问题,常用框格植草措施减缓雨水对边坡的冲刷破坏,加快坡面的植被恢复进程。结合广西贺巴高速来都段石漠化边坡植被恢复项目,通过对现场工程技术的实际应用情况进行跟踪调研,剖析了石漠化边坡框格内填土植草的植被恢复和生态防护技术在应用中发现的一些技术问题,提出了框格内填土局部稳定技术的新型解决方案,并进一步在该石漠化边坡,推广应用了采用水土共蓄的新型板槽进行植被恢复和生态防护的最新发明技术,以期对石漠化边坡的植被恢复提供积极的技术措施和建议,促进石漠化地区绿色公路建设的发展。

Vegetation restoration and ecological protection of rocky desertification slopes are popular issues in the construction of green highways at present.Slope lattice engineering measures are commonly used to slow down the rain erosion damage to slopes,and accelerate the vegetation restoration process on slopes.Vegetation was restored on a rocky desertification slope at Laidu Section on Heba expressway in Guangxi.Based on this project,some technical problems of lattice vegetation restoration and ecological protection on an excavated and rocky desertification slope were analyzed through field investigation.Some technical solutions such as improvement of local stability of the filled soil in the lattice were put forward.A new type of plate groove filled with soil and water in layers were further introduced and applied for vegetation restoration and ecological protection.The latest invention technology of vegetation restoration and ecological protection using a new type of soil and water storage board groove has been promoted and applied,in order to provide positive technical measures and suggestions for vegetation restoration of rocky desertification slopes and promote the development of green highway construction in rocky desertification areas.
