摘　　要：针对公路边坡植被恢复过程中,实生苗灌木在草灌混播群落中生长困难的问题,应用生态学实验方法,以灌木柠条为代表进行草本-灌木混播配置模式实验研究。研究表明:适当低密度草本植物可增加柠条出苗率;草本植物覆盖度影响柠条生长能力及存活率,柠条生长最适群落覆盖度为30%;草灌混播群落中,柠条存活的草本植物密度上限为750株/m2;草本植物对柠条生长和形态产生重要影响,其竞争抑制作用是自下而上发生的。In the grass-shrub mixed planting community,typically,growing difficulty of seeding shrubs make vegetation restoration of highway side slope a problem.To provide theoretical and technical basis for successful planting of grass-shrub community ecological experimental methods was used by taking Caragana microphylla as representative.The results showed that：Proper low density of herbaceous plants could increase emergence rate of Caragana microphylla;the coverage of herbaceous plants affected growing ability and survival rate of caragana microphylla,the optimum coverage of herbaceous plants in the community was 40%;in grass-shrub mixed planting community,the upper limit of herbaceous plant density to the survival of Caragana microphylla was 750 per square meter;the inhibitory effects from herbaceous plants on the growth of Caragana microphylla often began from the lower part to the upper part of Caragana microphylla.
