北京山区公路大多为盘山或沿溪走向,为满足公路技术要求必须开山或架桥,对沿线生态环境的破坏难以避免。因此如何维持原有生态平衡、恢复植被是山区公路建设中需要研究和探讨的重要问题之一。文章着重阐述了运用工程和绿化相结合的手段解决北京山区公路建设与生态恢复的问题,将生态平衡恢复到建设公路以前的水平或有所提高。增加公路经过地区的绿量,改善局地小气候,防治水土流失。防护公路,保证行车安全,为行旅提供舒适环境。提高公路沿线自然景观价值。弃渣边坡植被恢复,种植密度考虑近期和远期效果相结合,植物配置考虑乔灌木相结合,常绿和落叶相结合,绿叶植物和色叶植物相结合,形成多层次、多色彩、立体覆盖的景观效果。
Most of the mountainous areas in Beijing are either Panshan or Yanxi. In order to meet the technical requirements of the highway, mountains and bridges must be built and the damage to the ecological environment along the route inevitable. Therefore, how to maintain the original ecological balance and restore vegetation is one of the most important issues to be studied and discussed in the construction of mountainous highway. The article focuses on the use of engineering and greening a combination of means to solve the Beijing mountain highway construction and ecological restoration issues, the ecological balance restored to the level before the construction of the road or increased. Increase the green of roads passing the area, improve local microclimate and prevent soil erosion. Protection of roads, to ensure traffic safety, to provide a comfortable environment for travel. Improve the natural landscape value along the highway. Waste slag slope vegetation restoration, planting density Considering the recent and long-term effects of the combination of plant configuration considering the combination of arbors and shrubs, evergreen and deciduous combination of green plants and leafy plants combine to form a multi-level, multi-color, three-dimensional Covered landscape effect.
