摘要
针对高原高寒地区工程走廊创面中保水保肥性能差,人工植被建植难等特点,通过川藏铁路拉林段植被修复工点现场调研、室内试验和现场试验等方法,发明2种植被建植改良技术,即插播式建植技术和曲型植被纤维毯建植技术。研究结果表明,2种植被建植技术均能解决高原高寒地区保墒性能差、植被覆盖度低等问题,修复效果良好,植被覆盖度较高,有效解决了区域内植被建植难的问题,具有显著的经济效益和社会效益。
Aiming the water and fertilizer retention performance of engineering corridor wounds in plateau and al⁃pine area,and the difficulty of artificial vegetation establishment technology,through field investigation,laboratory test and field test of vegetation restoration site in Lhasa-Linzhi section of Sichuan-Tibet Railway,this paper invents two vegetation establishment and improvement technologies which are curved vegetation fiber blanket planting tech⁃nology and planting type restoration technology.The research results show that the two vegetation establishment tech⁃nologies can solve the issues of poor moisture retention and low vegetation coverage in plateau and alpine area.The restoration effect appears good,and the vegetation coverage retains high.It effectively solves the issue of difficult vege⁃tation establishment in this area with economic and social benefits.
