摘　　要：对邵(邵阳)怀(怀化)高速公路隆回至洞口段石质边坡进行了植被灌草化建植,建植时应做到:①根据研究区域的气候特征,选择狗芽根、百喜草、类芦等草种作为先锋种,选择耐旱、耐寒、耐瘠薄土壤的乡土灌木种——夹竹桃、紫穗槐、火棘及猪尿豆作为建群种(又称目标种),选择乡土植物——刺槐、山合欢等小乔木作为伴生种;②植被灌草化建植时,首先应进行坡面处理,然后用锚杆固定,在纱砂浆凝固且硬化后挂网,再分基层喷播和面层喷播2步进行基材喷播,喷播完成后及时覆盖无纺布。在灌草化植被形成后经调查发现,绿化覆盖度达90%以上,各项技术指标达到预期质量效果,表明边坡植被灌草化建植技术是快速恢复高速公路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 and herbagees established was conducted in the Shao-Huai Expressway which from Longhui to Dongkou in Hunan province.These methods was used ①According to the area climate,Cynodon dactylon,Papalum natatum,Sorghum bicolor （L.） Moench were selected as pioneer species,native shrub species including Nerium ndicum Mill.,Amorpha fruticosa,Pyracantha fortuneana,Mycoplasma organism,which were tolerant to drought,cold and barren,were selected as constructive species（the target species）,native dwarf trees including Robinia pseudoacacial and Albizia kalkora were selected as accompanying species.②During the shrubs herbage 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 herbage vegetation was established,the green coverage was above 90%,all the quality indexes were achieved prospectively.The most effective method for technology of suitable shrubs herbage widely established on expressways slopes was justified as the most effective method for vegetation restoration on the rocky slopes of expressway,and could be applied extensively in the same climate areas.
