摘要 本研究对贵阳市环城高速公路南环线的岩石边坡植被绿化护坡的效果进行了分析。结果表明:采用机械喷播乔、灌、草种子的方法进行绿化护坡可取得较好的效果;土质边坡植物生长状况优于石质边坡;阴坡植被修复效果优于阳坡;对于人工定植的植物应注重选择抗性较好、耐干旱瘠薄、生长较快的植物种类;刺槐、黄花槐、木豆、胡枝子、白三叶、高羊茅和黑麦草等乔灌草植物种子适宜混合喷播,并可在陡峭岩石边坡上生长。 By setting up 11 representative fixed sample plots,vegetation restoration in rocky slopes of south loop freeway of Guiyang City was analyzed and assessed.The results showed as follows:(1) hydroseeding of abors,shrubs and grasses could result in better effect;(2) growing performance of the plants was better in soil slope than in rocky slope,and the vegetation restoration effect in shady slope was better than in sunny slope;(3)as for artificial planting,much attention should be paid to the selection of plant species with high drought-barren resistance and fast growing feature;(4)some plant species were suitable for mixed hyddroseeding,including Robinia pseudoacacia,Sophora xanthantha,Semen cajani,Lespedeza bicolor,Trifolium repens,Festuca arundinacea and Lolium perenne,et al.,and they could grow well in steep rocky slope.
