码石扦插联合生态护坡技术研究及其应用

为探讨码石扦插柳干措施在边坡治理中的适用性,系统地介绍了该技术的施工方法,并对其生态效果进行了调查。以北京市延庆县上辛庄水土保持试验示范基地码石扦插柳枝护坡小区为例,对扦插植物生长情况、根系生物量和土壤理化性质性进行了调查分析。结果表明:完工4a后,试验小区旱柳成活率达到94.19%,旱柳生长状况良好,枝繁叶茂,坡面生境得到较快恢复,物种多样性增加,土壤理化性质有所改善,坡面稳定性增强,土壤剪切力增大,水土保持效果显著。最后总结了码石扦插联合措施在边坡防护中的施工要点以及后期管理措施,以期实现该技术的推广应用。

Construction and Application of Willow Cutting and Riprap Stacking Technology for Side Slope Protection

In order to discuss the suitability of willow cutting and riprap stacking technology methods used in side slope management,the construction method of joint planting is introduced and the functions of the method including strengthening riprap stability,purifying soil quality,improving habitat and beautifying the landscape,are discussed.Using the willow cutting and riprap stacking technology in demonstration basement,Yanqing County as the case,the performances of cut plants,root biomass and shoot bends are investigated.The results show that the Salix matsudana grows well.Survival rate of Salix matsudana after four years construction reaches 94.19%.The Salix matsudana has a deeper root system and has a good reinforcing function in the deep soil.What’s more,it has satisfactory bending and restorable properties.Flexible and bending branches cover the slope and protect slope from water erosion.At last,this paper discusses the construction characteristics and key implementation points of willow cutting and riprap stacking technology in order to popularize and apply this method.
