| 摘 要： | 选择高速公路生态边坡8种灌木根系,从根长、根量、根系削弱系数3个参数对其根系垂直分布特征进行研究,结果表明根系垂直分布大体呈现出由土壤表层至深层逐渐下降的趋势。但不同灌木根长、根量和根系削弱系数均在不同径级、不同土层中存在着较为明显的垂直分布差异。

| Abstract: | Eight kinds of shrub roots in the ecological slopes along highway were selected and their vertical distributions in root length,root volume and root extinction coefficient were researched.The results indicated that the roots of eight shrubs were basically decreased from the soil surface layers to the deeper layers.However,the roots length,weight and root extinction coefficient were obviously different in vertical distribution between the shrubs,between the diameters of roots and between the soil layers. |
