Study on the Habitat of Potentilla chinensis on Riverside Land in the Middle Reaches of Kiso River

Abstract

The habitat characteristic of Potentilla chinensis as the index species of gravelly river bed was considered on the planned park site in the dry riverbed in the middle reaches of Kiso River. The distribution situation was investigated by the target of all, and it was counted approximately 20,400 individuals of P. chinensis. As for the distribution of P. chinensis, it was almost delimited to a high-positioning dry riverbed, and it was clarified that this ecotope was the main habitat of this plant species. We presented the ecological planning flow as applied use of the natural environmental information map, which was prepared topographical map and vegetation map in this study.
