抄録

Universal Soil Loss Equation (USLE), originally developed by the USDA for agricultural lands and then used throughout the world,was applied in mountainous forest terrain in Japan. The slope length and steepness factors were extended for long slope lengths andsteep slopes by recalculating the data from available literature in Japan and by using data from supplementary erosion experiments.As such, we conclude that the USLE can be used successfully to estimate surface erosion on long, steep mountainous forest slopes.The cover and management factors of many kinds of natural and artificial forest stands, cutting types, and disturbance regimes werecalculated from the literature. The support practice factors of many types of soil and water conservation practices were also calculatedfrom published information. Based on these results, we showed that the USLE can be applied to estimations of soil erosion fromwide areas including many kinds of agricultural and forest lands.
