Abstract:
Construction of expressways and railways results in bare slopes and degraded ecosystems. Vegetation restoration with proper plant species is the foremost work in the restoration of the degraded roadside slopes. The climate of alpine region is featured with low temperature, short growing period, strong radiation, and low but concentrated precipitation, which are harsh for restoring vegetation. This research aimed to select proper plant species adaptable to the environment of alpine region and suitable for roadside slope restoration. We recorded the coverage and height of each plant present in the 120 plots along the G318 road in the eastern part of Tibetan Plateau. The investigation found 108 vascular plant species in the alpine roadside slope, including 17 artificially planted species. Most planted species belonged to Poaceae and Fabaceae. Lolium perenne, Elymus nutans, Melilotus officinalis, and Medicago sativa grew well on roadside from the altitude of 3000 m to 4100 m. Naturally regenerated species were mainly distributed in older slopes formed 3-5 years ago. Two species groups could be identified by the species characteristics: invasive species and spread species. The spread species contributed most to the biodiversity and complicated community structure in older slopes in Zheduo Mountain and Jianziwan Mountain. Naturally regenerated shrubs, such as Potentilla fruticosa, Piptanthus nepalensis, and Caragana franchetiana, could be planted artificially to improve the protection effect of vegetation. We also found that some bryophyte species, which are drought and cold tolerant, could be used as slope protecting species. The vegetation restoration of roadside slope in alpine region is a long lasting process. Artificial restoration of the secondary bare slope with proper plant species could result in healthy ecosystem with natural succession.
