- Abstract:
-
In order to assess the effect of vegetation restoration along the highway, a case study was conducted on the revegetated land along the Baoniu highway by investigating the characteristics of vegetation communities, species diversity and aboveground biomass on the embankment, cutting, residue field, shoulders, dug field. The results showed that: (1) Species diversity of Baoniu highway was abundant, and most of which were native grass species, indicating that it was still at the initial stage of vegetation restoration. (2) Plant species richness in five sites ranked as: natural>shoulders>residue field=dug field>embankment>cutting. No significant difference was found between road area vegetation and natural vegetation on indices of Shannon-Weiner, Simpson, and Pielou. (3) The framework seeding was the best model for embankment restoration while the geocel seeding is best for the cutting. (4) For the residue field, alfalfa should be planted to improve soil fertility, and to provide the sufficient nutrients for plants, covering with soil was necessary before planting.
