高速公路边坡生态防护研究现状与展望

随着我国高速公路建设快速发展以及人类环境保护意识的不断增强，边坡生态防护技术越来越受到重视，在高速公路建设中被广泛应用。边坡生态防护技术具有良好的经济效益、环境效益和社会效益，是公路建设工程中可持续发展的重要对策之一。目前，边坡生态防护技术在我国尚缺乏系统的研究和总结。结合工程实践，从边坡生态防护原理、护坡植物选择、生态防护施工方法及其经济效益比较等方面，研究和总结我国高速公路边坡生态防护技术的发展现状，指出存在的问题，提出进一步研究的方向。

Current state and prospect of research on ecological protection of rock slope in expressway

With the rapid development of the construction of expressway and the increasing sense of envi-ronment protection of mankind in our country,the bioengineering techniques for slope protection are be-coming more and more important and being used widely in the construction of expressway.It has good ef-fect in economy,environment and society,and it is one of the important measures for sustainable develop-ment on highway construction.Up to now,there have been no systemic research and conclusion on the bioengineering techniques for slope protection in China.Combining with the engineering practices,the pre-sent researching and developing situation in China on the theory of slope bioengineering protection,the se-lection of slope protection plants,the construction methods of bioengineering and the contrast of its eco-nomic effect have been studied and concluded.The existing problems were proposed,and its further re-search direction was put forward.
