中文摘要	以山东省中部半干旱地区济青南线济南至莱芜高速公路部分石质边坡客土喷播生态防护试验工程为研究对象,通过应用样方调查法对试验研究区内的路堑岩石边坡原生和次生生态恢复植被进行了随机调查.结果表明,客土喷播和植生带绿化等是实现开挖山体坡面的快速植被恢复的边坡生态防护措施,次生植被恢复演替进程比自然植被恢复明显加快.从植被种群的物种重要值、生态位宽度、生态位重叠等计测结果发现,在次生植被恢复过程中逐渐形成以紫花苜蓿、高羊茅、紫穗槐、多年生黑麦草、马棘等为主的重要值较高的草灌型植被,演替趋势为豆科草向豆禾草演替,多草型向草灌型演替,种间资源竞争不强证明边坡植被恢复1.5a时期的植被仍处于演替的初级阶段.
英文摘要	By taking the ecological slope protection of Ji’nanLaiwu expressway located in the semi-arid region of middle Shandong Province as a research object,the vegetation restoration of rocky slope by external-soil spray seeding technique is investigated based on the ecological slope restoration observations.Results show that the succession process of secondary vegetation restoration is more rapid than natural vegetation restoration.By calculating and measuring the important value,niche breadth,and niche overlap of species,rocky slope has gradually evolved into the grass-shrub vegetation with importance value,such as alfalfa,tall fescue,amorpha,perennial ryegrass,and indigofera pseudotinctoria,which range from leguminosae grass to leguminosae and gramineae grass and from multi-grass type to grass-shrub vegetation.The weak competition among species for resources proves that plants during one and a half year’s vegetation restoration period remain in the primary stage of succession process
