我国高速公路边坡植被防护现状与展望

Status and Prospect of Vegetation Protection on Expressway Slope in China

为推动我国高速公路边坡植被防护技术的发展,首先,采用现场调查和GIS数据叠加分析法,探讨了我国高速公路边坡植被防护现状。通过对比分析植物种类、植被覆盖度等指标,指出影响不同区域边坡植被防护效果的关键因素为气候因素和地质地貌因素。在此基础上,分析发现目前我国高速公路边坡植被防护存在的问题主要体现在理论和技术应用等方面;不同区域高速公路边坡植被防护技术相似,但防护现状存在明显差异。最后,有针对性地提出未来的发展建议,明确未来应重点关注不同防护技术的适用性、植被选择和配置以及可持续植被管理等问题。

In order to promote the development of vegetation protection technology for expressway slope in China, field investigation and GIS overlay analysis were used to analyze the status of slope protection. Based on the observation of plant species and vegetation cover of different vegetation protection, it is found that key factors affecting the effect of vegetation protection are climatic factors and geomorphological factors. In general, problems of vegetation protection on expressway slope are mainly reflected in the application of vegetation restoration theory and conventional technology;vegetation protection technologies of expressway slope in different regions are similar, but situations of vegetation protection are different. Therefore the development direction should focus on the applicability of protection technologies, the selection of vegetation and the management of sustainable vegetation in the future.
