以位于陕北黄土高原的延安、榆林和横山3个气象站的月雨量数据和年雨量数据对Wischmeier、Renard、刘秉正等研究的7种降雨侵蚀力简易计算模型进行验证,将计算结果与陕北黄土高原降雨侵蚀力基准值进行对比,发现刘秉正提出的渭北地区R计算模型较其他模型与基准值比较接近。但是,由于该模型的相对偏差仍然较大,所以,对于陕北黄土高原来说,应该根据当地的气象条件,研究出适合当地的模型。
Seven kinds of rainfall erosivity simple calculation models studied by Wischmeier, Renard and Liu Bingzheng were verified by monthly and monthly rainfall data of three weather stations in Yan’an, Yulin and Yokoyama of the Loess Plateau in northern Shaanxi Province. The results were compared with those of Shaan North of the Loess Plateau rainfall erosive reference value comparison and found that Liu Bingzheng Weibei R calculation model compared with other models and the benchmark values are close. However, due to the relative deviation of the model is still large, so for the northern Shaanxi Loess Plateau, should be based on local weather conditions, developed a suitable local model.
