摘要
通过对比分析研究了二种不同生态护坡工法对边坡绿化效果的影响,得出应用型框喷播技术进行坡面绿化有更好的景观效果。二组试验坡面分别采用植生喷播技术(Hydromulching System)和型框喷播技术(Soil Create System)进行了绿化,对2005年、2009年和2014年的植物总盖度、生物量、物种密度、p H值、基材厚度等观测数据进行分析。结果表明,从1999年开始试验,应用此两种生态治理工法的四个坡面经过十五年的自然演变,均保持良好的植被覆盖率,最低为80.6%;型框喷播比植生喷播技术更具优势,坡面基材流失较少,植被覆盖率较高,是一种更能长期保持边坡美化效果的治理方法,由此总结出利用工程措施防止基材流失是维持客土喷播边坡长期性绿化效果的关键因子。
This paper studied the effects of two greening technologies on maintaining and greening of slope,and try to find the optimummethod for slope protection.Two slopes were made green by using Hydromulching System and Soil Crete System,respectively.Thegreening indexes of two slope including total coverage,biomass,density of plant,and pH value,the substrate thickness of soil wereobserved in2005,2009and2014.From beginning of the experiment,the results showed that after15years of natural evolution,the slopeskept high vegetation coverage by using two ecological governance methods,where vegetation cover rate was more than80.6%.Comparedwith the Hydromulching System,the technology of Soil Crete System was a more advantage method for greening and protection slope,which could keep higher vegetation coverage,plant density,and less base material loss.The Soil Create System has more long-termecological maintenance,protection,and greening effect.Moreover,the key factor of maintaining long-term vegetative greening for slopeusing technology of the Hydromulching System is by engineering technology to prevent and control the loss of slope base material.
