边坡植被恢复是解决高速公路修建后的环境问题的重要举措,也是路域生态植被恢复的难点。干旱半干旱地区环境恶劣,植物生长困难,边坡植被恢复在面临重大技术难题。文章选用了草坪种子植生带和PEWS无土草坪植生带进行了边坡防护研究试验,通过对生长速度、护坡能力、覆盖度等指标进行综合对比分析,表明草坪种子植生带建植前期发芽率、覆盖度等较好,能形成较好的初期防护效果。PEWS无土草坪植生带加工可加入适宜的肥料和保水剂,麻纤维保水效果好,后期植物生长较好。文章提出了植生带边坡防护应从当地的实际出发,结合边坡坡度,水分供给情况、养护力度等,选择最适合的植生带品种和建植方式。
Slope vegetation restoration is an important measure to solve the environmental problems after the construction of expressway, and it is also a difficult point for ecological restoration of roadsides. In arid and semi-arid areas, the environment is harsh and plant growth is difficult. The restoration of the slope vegetation is facing major technical problems. In this paper, turf seed-vegetative belt and PEWS soil-less turf vegetation belt were selected for slope protection study. The comprehensive comparison of growth rate, slope protection ability and coverage showed that the rate of germination, Better coverage, can form a better initial protection effect. PEWS soilless turf vegetation processing can be added to the appropriate fertilizer and water retaining agent, hemp fiber water retention effect is good, the late plant growth is better. The article puts forward that the slope protection of vegetation zone should be based on the actual conditions of our country and the most suitable species and establishment of vegetation zone should be selected according to slope slope, water supply and conservation.
