【摘要】 以京承高速公路三期边坡植被恢复工程为依托,探讨了草豆模式(以草本为主豆科为辅)和灌草模式(以灌木为主以草为辅)两种植物配置模式在植被防护初期的恢复效果。结果表明:灌草模式初期形成的群落坡面覆盖度呈现逐步增加趋势,复层特征日渐明显,而草豆模式前期增加迅速,在播种3个月出现峰值后,覆盖度出现了下降;在高度变化上,草豆模式中的禾草增长快于豆科植物,且在播种3个月后达到峰值,其对豆科生长产生一定影响,而灌草模式中播种前2个月各类植物高度逐步增加,随后野菊花的高度生长迅速增加,群落中的其他植物受到抑制,群落中的植物平均高度大小顺序依次为:野菊花>紫穗槐>豆科植物>禾草>胡枝子:在出苗后2个月后的7、8月份,野生杂草竞争优势日益明显,灌草模式群落中杂草种类大于草豆模式群落,杂草入侵有利于初期的边坡防护效果,两种植物配置模式在边坡防护中初期的恢复效果差异明显。更多还原

【Abstract】 Based on vegetation restoration engineering along Beijing-Chengde expressway(third period),earlier vegetation restoration were studied and discussed for two plant disposition pattern, including Grass-legume pattern and Shrub-grass pattern.The results showed that:plant coverage of Shrub-grass pattern showed increasing trend gradually in early four month,and complex storey of structure appeared distinct increasingly.However,plant coverage of Grass-legume pattern showed descend after three month,which period plant coverage reached biggest.In Grass-legume community,grass grew more rapidly than legume in height,especially in earlier three month.The grass have inhibiting effect on legume.In Shrub-grass pattern community,every plant grew steadily in earlier two month.Subsequently,Flos Chrysanthemi Indici grew more rapidly than other plant in community.Average growth height in Shrub-grass pattern community is Flos Chrysanthemi Indici>Amorpha fruticosa L.>legume>grass>Lespedeza bicolor Turcz..In July and August,wilding plant showed competitive intensity in Shrub-grass pattern community.wilding plant species in Shrub-grass pattern community is more than that in Grass-legume pattern community.But wilding plant is helpful in earlier vegetation restoration. Two Plant disposition pattern showed obvious difference in earlier vegetation restoration.更多还原
