摘　　要：2008年在北京市密云县潮河河坡进行灌草植物护坡组合模式的筛选,以护坡植被质量评价6种灌草种植模式,应用灰色系统理论对密云潮河护坡不同种植模式的护坡植被质量进行了分析和评判,确定最优灌草组合模式。结果表明:荆条(Vitex negundoL.var.heterophylla(Franch)Rehd.)+小冠花(Coronilla variaL.)+白三叶(Trifolium repensL.)+高羊茅(Festuca arundinaceacv Fine Lawn)混植护坡植被质量最优,可以有效地护坡;高羊茅和小冠花是优秀的护坡植物,适用于北京地区固土护坡。Six shrub-grass composite cultivation modes were established in 2008 on the degraded riversides of Chaohe River in Miyun County,Beijing and the slope-protection vegetation qualities of different cultivation modes were evaluated using grey correlation analysis.The results show that the cultivation mode of Vitex negundo L.var.heterophylla（Franch） Rehd.＋ Coronilla varia L.＋ Trifolium repens L.＋ Festuca arundinacea Schreb.cv.Fine Lawn had the best slope-protection quality and effectiveness.In summary,F.arundinacea and C.varia are excellent slope-protection plants for slope reinforcement and protection in Beijing areas.
