As an importantmethod of solving the environmental problems caused by the construction of expressway,slope revegetation attracts much attention. However,an evaluation index system for the quality of slope revegetation thatcan be accepted by experts is notavailable. Based on the thoughts of restoration ecology and aesthetics and the analysis of functions of slope vegetation,eightimportantevaluation indexes of green period,coverage,richness degree,interception flux,comprehensive resistance,stabilizing effectof rootsystem,beauty degree of landscape,and managementlevel were presented and calculation method for each index was proposed using the theory of road engineering,vegetation ecology,restoration ecology,grass ecology,soil and water conservation,and landscape science. The weightof each index was determined by means of the Analytic Hierarchy Process judging matrix. Based on the succession law of slope vegetation community,proposed evaluation time was given,evaluation score of slope re-vegetation was calculated,and quality grade was determined. Finally,the Ji’nan -Qingdao expressway II,which will serve 2008 Beijing Olympic Games,was also introduced as a case study.
