土壤生物工程在北京山区公路绿化中的应用

Application of Soil Biotechnology to Road Slope Revegetation of Beijing Mountainous Region

山区公路边坡绿化不仅可以保护边坡,防治水土流失,而且还可以改善公路施工过程中对环境造成的创伤,已经成为公路边坡治理的重要内容.以北京市怀柔区琉璃河岸坡为试验示范区,以旱柳(Salix matsudana)作为主要的绿化植物,采用扦插、埋根、灌丛垫、柳篱挡墙、梢捆等土壤生物工程措施,对沿河公路路基边坡进行治理,并对施工完成5个月后的生长状况、护坡效果等进行观测调查.结果表明:5种土壤生物工程中旱柳的成活率均在90%以上,在试验区具有很好的适应性;在不同的工程类型、水淹与否等条件下,旱柳的生长状况表现出明显的差异,各措施按旱柳生长状况由好到差排序依次为梢捆、灌丛垫、埋根、扦插、柳篱挡墙;水淹1个月的旱柳基径和株高较未水淹的平均值分别小13.2%和21.4%.水利论文EQ\'NuJ y
