Abstract
Revegetation on an artificial bedrock cut slope of a dry ridge area was evaluated from the aspect of target plant communities. Adaptability of the sowing revegetation methods and artificially introduced species were investigated. Shrubs consisted of species invading from surrounding vegetation, and introduced nut-bearing species were set as long-term targets of revegetation. The growth material spraying method, mat method, and the growth material injection method were chosen to accomplish the targets, with seeds arranged for each target. The plant communities formed were researched continuously for eight years. The nut species plots from the mat and growth material injection methods formed the target communities in the eighth year. In the first year, these experimental plots had low coverage ratios of <17%; however, target communities were formed. These revegetation methods were highly erosion-proof; no erosion problems were encountered in the beginning after construction when the coverage ratios were low. It is concluded that the growth material injection method was superior to the others and was most reliable for forming shrub-dominated nut species with increased cover speed, a higher number of individual nut-bearing species, and vigorous growth.
