摘　　要：青海省属于高原大陆性气候,生态环境敏感和脆弱。公路建设过程中需要大量的开挖和回填,进而形成高填路基或深挖路堑,对沿线自然生态环境造成不可逆的影响。主要表现在水土流失严重,植被遭到破坏,同时在降雨和冰川融水的不断作用下可导致山体滑坡、泥石流等自然灾害。我国近些年陆续开展了公路、水路相关生态型工程的试点和探索,尤其在青海高原地区取得了显著成效。本文依托青海省在建公路项目,分析植物边坡防护的必要性,常见的公路路基边坡病害,以及边坡坡面防护类型和植物边坡防护的工程实例应用。最后总结出在高寒高海拔地区公路边坡植物生态防护技术实施的要点,可为类似工程提供技术支撑和借鉴。Qinghai Province belongs to the plateau continental climate and the ecological environment is sensitive and fragile.In the process of highway construction,a large amount of excavation and backfill are required to form a high fill subgrade or deep excavation of trenches,which has an irreversible impact on the natural ecological environment along the line.It is mainly manifested in serious soil erosion,destruction of vegetation,and even landslides and debris flows under the continuous erosion of rainfall and glacial meltwater.In recent years,China has successively carried out the pilot and exploration of ecological projects related to highways and waterways,especially in the Qinghai Plateau,and has achieved remarkable results.Based on the highway project under construction in Qinghai Province,this paper analyzes the necessity of plant slope protection,the common highway subgrade slope diseases,as well as the types of slope broken surface protection and the engineering example application of plant slope protection,and summarizes the key points of the implementation of plant ecological protection technology for highway slope in alpine and high-altitude areas,so as to provide technical support and reference for similar projects in the future.
