降雨侵蚀土壤流失预报方程又称土壤流失通用方程(USLE),在美国已有四十多年研究历史,并获得成功。早在十多年以前,美国农业部就以农业手册形式正式颁布了此预报方程,并推广应用,以作为估算地表土壤流失量和进行坡地水土保持规划的指南。目前,世界许多国家,包括日本和澳大 Rainfall erosion The soil loss prediction equation, also called the general equation of soil erosion (USLE), has been in the United States for more than four decades and has been successfully studied. As early as more than 10 years ago, the USDA formally promulgated this forecasting equation in the form of an agricultural manual and popularized the application as a guide for estimating the amount of soil erosion on the surface and planning water and soil conservation on the slope. At present, many countries in the world, including Japan and Australia
