对湖北沪蓉西(宜昌-恩施)高速公路路段的K161+127～K161+342左幅路堑石质边坡进行了植被灌木化的建植研究.根据研究地区的气候特点,选择暖季型草坪草种狗牙根和百喜草作为先锋种,选择耐旱、耐寒、耐瘠薄土壤条件的乡土灌木种多花木蓝、紫穗槐、火棘及胡枝子作为建群种(也叫目标种),选择乡土植物刺槐、山合欢等小乔木作为伴生种.植被灌木化建植时,首先进行坡面处理,然后用锚杆锚固,在砂浆凝固且硬化后挂网,再分基层喷播和面层喷播两步进行基材喷播,喷播完成后及时覆盖无纺布.在灌木化植被形成后观查发现,绿化覆盖度达95%以上,各项技术指标达到了预期质量效果,表明边坡植被灌木化建植技术是快速恢复高速公路路堑石质边坡植被的有效途径,可以在同类气候地区推广应用.

The technology of shrubs widely established was studied during the vegetation restoration on the cutting rocky slopes in left,of the Hu-Rong West Expressway (K161+127～K161+342)from Yichang to Enshi in Hubei province. According to the area climate,warm-season grasses Bermudagrass and Bahiagrass were selected as pioneer species,Native shrub species Indigofera floribunda,Amorpha Fruticosa,Pyracantha fortuneana and Lespedeza bicolor,which were tolerant to drought,cold and barren,were selected as constructive species(the target species),native dwarf trees Robinia pseudoacacial and Albizia kalkora were selected as accompanying species. During the shrubs established engineering,slops were treated,anchored,then covered with nets after the mortar solidified and hardened,and then the basic materials were sprayed including substrate spraying and surface spraying,at last slops were promptly covered with non-woven fabrics. After the shrubs vegetation was established,the green coverage was above 95%,all the quality indexes were achieved prospectively. The results show that the technology of suitable shrubs widely established on expressways slopes was justified as the most effective method for vegetation restoration on the cutting rocky slopes of expressway,and could be applied extensively in the same climate areas.
