摘要

碎石填方边坡是山区公路常见的一种坡面类型。表层为以碎石为主的土石混合体，土壤含量极少甚至没有，立地条件恶劣，导致坡面植被恢复非常困难。针对这一难题，以北京市门头沟区百花山旅游公路11 km处的45°碎石填方边坡为研究对象，采用"客土+保育块苗移栽"技术，在坡面上重建了乔灌草植物群落。施工4 a后，坡面草本植物群落的总覆盖度约为50%，平均高度约为40 cm；坡面木本植物生长状况良好，主根粗壮、根系发达且已深入碎石缝隙之中，其中山桃保育块苗的成活率为78%，高度为82 cm，地径为7.9 mm。实验结果表明，该方法可以在比较陡峭的碎石覆盖边坡上有效地构建乔灌草植物群落。

Abstract

Rock fill slope is a common slope type on mountain roads with surface layer consisting of different sizes of broken rocks but little soil

this poor site condition brings great difficulty to the vegetation restorat ion.To solve this problem

the tree(shrub)herb community was constructed using the nursery block and soil spray-sowing technique.Taking the 45b rock fill slope at the 11km of Baihuashan tourism road in Mentougou

Beijing City as an example

the coverage of her baceous plants was around 50%

and the average height was 40 cm four years later after the technique was use.Meanw hile

the woody plants grew well with sturdy taproots and strong lateral roots penetrating into rock cracks

and the survival rate of Prunus davidiana was 78% with the height of 82 cm and the ground diameter of 7.9 mm.The results showed that the tree(shrub)herb community could be successfully constructed on relatively steep rock fill slopes by using t his technique.
