摘　　要：对植物根系固坡和化学类有机高分子灌浆材料固坡进行对比研究,得出如下结论:植被固坡主要适用于2 m以下浅层边坡的防治性处理;灌浆固坡适合于空隙较大土体、裂隙较多的堆积岩石坡体,灌浆体对植物无法涉足的次深层边坡有较好的治理效果,但灌浆固坡治理深度宜在7 m以内。This paper conducts comparative research on slope stabilization with plant root system and chemical organic polymer grouting materials and obtains the following conclusions：slope stabilization with plants is mainly applicable to preventive treatment of under-2 m shallow slopes;and slope stabilization by grouting is suitable for soil masses with large voids and rock accumulated slopes with many fractures. The grouting bodies show better treatment effect for deep slopes those cannot be reached by plants, but the depth of treatment of slope stabilization by grouting should be within 7 m.
