摘要: This study accomplished to draw a soil erosion map and grade of loss hazard in Korea. RUSLE Rainfall-runoff (R) factor, which was estimated by using the rainfall data observed 59 meteorological stations from 1977 2006 (for 30 years). FARD used analyze frequency, whole country R factor according frequency. In analysis estimating Nakdong river has smallest vaule, but Han biggest value. According result analyzing loss, occurred grass land, bare land field size order, also approximately 17.2 ton/ha happened on area. The average amount unit area takes place lot. total 5-year-frequency yields 15,000 ton and, what is more, lot happens paddy field, forest crop field. drawn up classifying 5. As moderate 2 largest part, 72.8% area, contrary, severe only (1.1%) cover shows respectively.
