黑龙江省水土保持科学研究所于 1 992年研究提出的适合本省采用的土壤流失方程式 ,除用于预报坡耕地土壤流失外 ,还可用于工程建设项目的土壤流失量预测。该方程式表达直观、计算简便、准确度高 ,应用于其他省区则应根据具体省区的资料确定各参数因子。介绍了该方程式及其各参数因子的确定方法 ,并以实例说明了方程式的应用 In addition to the prediction of soil loss on sloping arable land, the soil loss equation developed by Heilongjiang Provincial Institute of Soil and Water Conservation in 1992, which is suitable for the province, can also be used to predict the amount of soil loss in construction projects. The equation is intuitive, the calculation is simple, high accuracy, applied to other provinces and autonomous regions should be based on specific provincial data to determine the parameters of each factor. The method of determining the equation and its parameters is introduced, and the application of the equation
