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。
In this study, monthly and annual rainfall data from three weather stations, Yanan, Yulin and Hengshan, were used to cheek the adaptability of seven rainfall erosion models which were from W H WisChmeier, Renard, Liu Bingzheng et. The results were then compared to the reference value of rainfall erosion. It was found that the model from Liu Bingzheng was the most suitable one used in Weibei area. However, it still had shortcomings. For this area, specific models should be established according to local conditions.
