An initial approach to measure soil loss amount of farmland on weir and mound using ~(137)Cs method
Cs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。
Abstract
This paper describes the concept and method of estimating soil erosionrates of cultivated land from fallout Caesium137 measurements.The resultsof five soil profiles on cultivated land of weir and mound and terrace showthat the total content of ~(137)Cs 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.
