摘　　要：高速公路建设中一些深挖的岩质地段,通常会出现生态修复困难的高陡岩质边坡,用传统的修复方式很难成功复绿,研发出能成功修复这些边坡的技术对“美丽公路”建设具有重要意义。针对采用传统液压喷播边坡绿化技术不能修复的景海高速公路高陡岩质边坡进行生态修复攻关。分析了该高陡岩质边坡的立地条件,发现其土壤pH<2、多种有毒有害元素污染严重、岩石上基本没有土壤、坡度>45度,立地条件极端恶劣。我们用改进了的植生袋并配合植物选择和工艺种植技术进行生态重建。结果表明,工程实施14个月,成功将植被盖度恢复到98%以上,与周边自然系统相当,形成较稳定的群落结构,完成了攻关。结果为公路边坡绿化的可持续性发展提供科技支持,为科学合理开展困难地区边坡绿化与生态修复提供技术案例。In some deeply excavated rocky sections in highway construction,there are usually high and steep rocky slopes that are dfficult to restore their ecological functions,which are difficult to be restored by traditional restoration methods,it is of great significance to develop technologies that can successfully restore these slopes for the construction of"Beautiful Highway".In this study,the ecological restoration of the high and steep rocky slopes of Jinghai highway,which cannot be restored by the traditional hydraulic spraying technology,was studied.The site conditions of the high and steep rock slope were analyzed,and it is found that the soil pH is lower than 2,the pollution of various toxic and harmful elements is serious,there is basically no soil on the rock,the slope is>45 degrees,and the site conditions are extremely harsh.We used the improved planting bags and combined with plant selection and craft planting technology for ecological restoration.The results showed that the vegetation coverage was successfully restored to more than 98%,which equivalent to the surrounding natural system within 14 months,forming a relatively stable community structure,and the dfficulties were overcome.The results of this study provide scientific and technological support for the sustainable development of highway slope greening,and provide technical cases for scientific and rational development of slope greening and ecological restoration in difficult areas.
