文章通过典型工程进行技术和施工示范,研究适合在西部半干旱地区高速路建设中应用的生态恢复技术,是西部公路生态建设的要务之一。厚层基质喷附技术,能在坡面上形成植物生长发育所需的有一定厚度的有机质层,使植物种子有比较自然的发芽过程,可适用于各种边坡土质边坡、石质土边坡和岩石边坡。本文总结了自2003以来在我国西部半干旱地区高速公路应用厚层基质喷附技术进行边坡生态恢复与重建的经验,并对植物物种选取、施工方法、养护方法等进行了探讨。
The article carries on the technology and the construction demonstration through the typical project, studies the ecological restoration technology suitable for the highway construction in the western semi-arid area, and is one of the most important tasks in the western highway ecological construction. Thick substrate spraying technology can form a certain thickness of organic matter layer needed for plant growth and development on the slope, so that plant seeds have a relatively natural germination process and can be applied to all kinds of slope soil slope, stone soil Slope and rock slope. This paper summarizes the experience of applying thick-matrix spray technology to ecological restoration and reconstruction of slopes in the expressway of semi-arid areas in western China since 2003, and also discusses plant species selection, construction methods and conservation methods.
