【摘要】 研究西宁至马场垣高速公路植被建植的过程中,植物的演替规律和采取的管护措施。根据西宁地区的气候、地貌和土壤条件,针对植被养护当中存在的问题如养护成本高,群落结构不尽合理,盐碱比较重的问题,通过观察和试验,运用生态学原理对取得的数据进行分析,探讨本地区公路路域内植物的演替方向和目前养护措施存在的问题。根据已掌握的本地区植物群落演替规律,并考虑本地区高速公路对植被的特殊要求,提出针对性的建议和意见。研究结果表明:在公路路域内一个相对稳定的植物群落,应该是一个以耐旱灌木为主草本植物为辅的演替中间群。养护的重点是充分发挥自然的调节能力,减少人为干扰,培养相对稳定的植物群落,降低养护的成本。更多还原
