R. China. Belt transect and random quadrats were used in sampling and recording the vegetation of the four selected plots on the slopes. The community of each plot was characterized based on the coverage, relative importance value, richness, diversity, evenness of species derived from the survey data. Problems of these communities were identified and corresponding regulation measures were proposed to accelerate the positive succession process of the ecosystem. It is demonstrated that the artificial vegetation restoration on the excavated slope has improved the ecological environment.展开更多
