Abstract:: With the leapfrog construction of Xingfen highway of Hebei Province, ecological environment along the roadside is inevitably being destroyed. For the purpose of conserving water, stabilizing and protecting slopes, the ecological benefits of plants should be fully developed. The key to achieving the purpose is the selection of plant species and configuration of plant community. In terms of the field quadrat investigation, the result shows from the analysis of the number of plant species at different altitudes, laws of variance of important value and distributional conditions of plant association, that there are about 21 families, 41 genus, 48 species of vascular plants, of which 28 dominant species including 6 tree species, 6 shrub species and 16 herb species appropriate for slope revegetation of Xingfen Highway in Hebei Province have been screened.The important values of plant species change are greatly influenced by the altitudes. Of all species Robinia pseudoacacia, Ziziphus jujuba var. Spinosa, Lespedeza bicolor,Bothriochloa ischaemum, Arthraxon lanceolatus, Capillipedium parviflorum and Elymus dahuricus are influenced remarkably by the altitudes. The important value of species in the herb layer is the highest at every altitude, which can play an important role in pioneer species of slope revegetation. Of all families is the highest at every altitudes. Plant community alongside of the slope of Xingfen Highway in Hebei Province is divided into four plant associations. In the course of side-slope revegetation, four main plant associations can give reference to the configuration of plant community.
