摘要
本文对通用土壤流失方程式(USLE)在我国的适应性研究成果做了系统的总结。指出各地在引用USLE 模型时务必利用当地的实测资料确立本地的 R 值最佳计算组合,并对模型中其它5个因子的取值方法进行系统的研究,以确定适合我国情况的各因子取值,提高土壤流失预测预报的精度。
This paper summarizes systematically the research achicwments on the application of USLE in China,and points out that when making use of USLE pattern various tocaties must establish the local precise calculation combination of R value on the foundation of the actual data measured.The method of acquiring the values of other five factors in the pattern has also been researched systematically.So the values of the fac- tors based on our country can be determined and the precision of prediction and forecast on soil loss can be improved.
