This soil has the natural background of which erosion and runoff are productive by the weather condition of characteristics and rainfall of the distribution landform. And the outflow of reddish soil pollution is the environmental problem of sea area around Okinawa.\nIn this study the reddish soil sample was collected from Okinawa Island and Ishigaki Island, Kumejima Island, Miyako Island and Iriomote Island, and the indoor rainfall erosivity experiment was carried out. (The indoor rainfall erosivity experiment which belongs to source countermeasure of the reddish soil spill prevention countermeasure.) Disposition characteristic of the soil in the region is described on the basis of the experimental result., 紀要論文}, pages = {25--31}, title = {沖縄県地域士における流出特性に関する研究}, year = {2004} }
