摘　　要：根据USLE原理,本文提出了一种计算小流域土壤流失量的新方法,并用来计算宁夏西吉县黄家二岔小流域的土壤流失量,计算结果与实测结果接近。方法和方程中各因子的取值适用于其它类似地区。A new method and computer program were developed out to calculate amount of soil loss of small watershed based on the USLE (Universal soil Loss Equation), by which amount of soil loss of Huangjia-Ercha small watershed in Xiji county was calculated, and there is nearly no difference between the calculating value and value investigated on site. This method and the values of factor of USLE can be used in other similar regions.
