高原高寒草地线状工程施工迹地植被恢复研究

Research on Vegetation Restoration of Alpine Grassland Linear Engineering Construction Sites in Plateau

青藏高原是我国重要的生态安全屏障,被誉为亚洲乃至北半球气候变化的“启动器”和“调节器”,生态地位极其重要。同时,高寒、干旱、缺氧的气候特征使高原生态环境极为脆弱、敏感,自我调节和修复能力差,一旦破坏,极难恢复。而长输管线施工难免对高原沿线自然环境造成不利影响,如何保护好高原生态环境,做好施工迹地植被恢复成为项目管理的重中之重。本文通过经验总结和现场实践,取得了高原植被恢复阶段性成果,为后续高原线状施工迹地植被恢复提供借鉴。

The Qinghai-Tibet Plateau is an important ecological security barrier in China, known as the “starter” and “regulator” of climate change in Asia and even the northern hemisphere, and its ecological status is extremely important. At the same time, the climatic characteristics of alpine cold, drought and lack of oxygen make the plateau ecological environment extremely fragile and sensitive, and the self-regulation and repair ability is poor, and once destroyed, it is extremely difficult to restore. The construction of the long-distance pipeline will inevitably adversely affect the natural environment along the plateau, how to protect the plateau ecological environment, do a good job in the restoration of vegetation in the construction site has become the top priority of project management. Through experience summary and on-site practice, this paper has achieved the phased results of plateau vegetation restoration, which provides a reference for the subsequent vegetation restoration of plateau linear construction sites.
