摘　　要：确定土壤侵蚀量,传统的方法有水文法、径流小区观测法、浸蚀因子多元回归法等。这些方法,均需要较长系列的观测资料。本文应用通用土壤流失方程式,通过确定方程式中各因子值,对罗玉沟流域坡面土壤侵蚀量进行了推算,并以定点观测调查的结果进行了验证。The traditional methods for measuring the amount of soil erosion such as hydrological methods, methods based on runoffplot experiment,methods of rnulti- factor regression, require data of long term observation. .The amount of soil erosion on slopes in Luoyugou has been estimated in this paper through the evalution for the factor values in USLE and varified with the result of plot observation.
