| 摘要: |
| 随着我国高速公路建设的快速发展与人类环境保护意识的提高，边坡生态防护技术越来越受到重视，并在高速公路建设中被广泛应用。边坡生态防护技术不仅是护坡的措施，而且是生态系统恢复与重建的一种技术。文章结合工程实践，在对现有边坡生态防护理论的资料统计、分析及现场考察的基础上，从护坡植物的选择，边坡生态防护技术原理、分类及其应用4个方面进行探讨。以毛坝至陕川界高速公路为例，结合沿线边坡特性，调查、分析了不同边坡生态防护技术的原理、形式、特点、适用条件及实际护坡效果。结果表明，因地制宜地在高速公路建设中应用生态边坡防护技术，可以增强边坡的稳定性，抑制水土流失，营造良好的生态景观，构建稳定的生态系统，降低工程造价，节约维护成本，保证高速公路安全运行，具有良好的生态效益、经济效益及社会效益，以期为今后高速公路边坡生态防护工作提供参考。 |

| Abstract: |
| With the rapid development of the construction of expressway and the improvement of environmental protection consciousness of mankind in China，the slope ecological protection technology has attracted more and more attention and have been widely used in the construction of expressway，which is not only a way of protecting slope but also a kind of technology to restore and reconstruct the ecosystem.Combining the engineering practice，based on statistics and analysis of the date of existing theory of slope ecological protection and field investigation，this paperdiscussedthe selection way of slope protection plants，the principles，classification，and the application of slope ecological protection technology.Taking theexpressway Maoba to Shaan-Chuan boundary as example，the principles，forms，characteristics，application conditions and the actual effect of different slope ecological protection technology were investigated and analyzed combining the characteristics of slopes along the road.The result showed that applying slope ecological protection technology in highway construction according to local conditions could enhance the stability of slopes，conserve soil and water，construct a good ecology landscape，establish stable ecosystems，reduce project and maintenance cost，and ensure the safety of expressway operation，which had good environmental，economic and social benefits.This paper expected to provide references for the practical works of expressway slope ecological protection in the future. |
