Abstract:Plant-concrete grillage slope protection is a new technology for ecological slope protection.By taking asteep and bare slope located in Soil and Water Conservation Science and Technology Demonstration Park in Yanqing County of Beijing City as a research object,the applicability of the technology in Beijing City and itseffects in ecological restoration on slope were studied.Because of the existence of splash erosion,surface erosion,gully erosion and other types of soil erosion,the method combining plant cuttings and concrete grillage was used to restore bare slope near-naturally.After 3,15and 47months of construction,survival rate andcoverage degree of Salix metsudana were investigated and monitored,including the growth conditions,soilnutrients and biological diversity of 47-month-old Salix metsudana.It can be concluded that the growth ofSalix metsudana using this technology has reached a higher level.The average branch diameter of 47-monthold Salix metsudana was 2.02cm and the average stem height,317.2cm.Meanwhile,vegetation on sloperecovered rapidly,biological diversity increased obviously,and soil properties were improved somewhat.
