Other Abstract 本文介绍了137Cs法测算农耕地土壤侵蚀量的基本原理和方法。梁峁坡农耕地和梯田5个土壤剖面的137Cs含量的测定结果表明,土壤剖面的137Cs总量很好地表征了农耕地的侵蚀程度。根据卡钱诺斯基和奎因(Kachanoski and Quine)1987年分别提出的曲线和本文提出的公式求得的侵蚀模数值和实测资料分析值基本吻合。 
; This paper describes the concept and method of estimating soil erosionrates of cultivated land from fallout Caesium-137 measurements.The resultsof five soil profiles on cultivated land of weir and mound and terrace showthat the total content of 137Cs in soil profile reflect erosion severity ofcultiated land well.The soil erosion rates,indicated by Kachnoskis and Quinescurves and calculated by the formula developed by authors,are basicallyconsistent with the analyzed values based upon measured data of runoffplots.
