The purpose of this research is to evaluate riverside open space vegetation with restoration from the ecological viewpoint. The species composition at riverside open space was investigated in order to examine life-form composition, degree of succession and species diversity.
The site refilling with topsoil; a kind of restoration was completed by annual species (Ambrosia artemisiaefolia and Kummerowia striata) in the first year after construction. In the next year, the site refilling with topsoil was dominated by perennial species (Artemisia princeps and Solidago altissima). The value of degree of succession was identified as the general stage of secondary succession. It was judged that the secondary succession was on a progressing state. But, it was afraid if an alien species (Solidago altissima) remains overgrown on the refilling site for a long time, it would cease a natural succession.
