| 摘 要： | 本文基于侵蚀雨量与其总动能之间普遍存在极高的相关性和相近的关系式,建立了由汛期雨量和I30B组成的R新算法.它在各地的应用结果表明,新算法比已有算法的应用范围广,监测流失量的精度高,且易于在遥感监测中应用.它能以统一方法和精度来评价全国水蚀区的R差异,为水土保持工作的科学管理服务.

| Abstract: | According to very high correlation existing generally between erosive precipitation and ltinetic engery,a nrw algorithm of R composed of the I30B a and the precipitation of flood xason has been initially created.Application results of new and old algorithm in different region show that the new algorithm was wider in application range,higher in the accuracy of monitoring rrosinn loss and easier to the usage in remote sensing monitoring of erosion losxs.Using the new algorithm,the R values of all rainfall erosion regions in China could be calculated and evaluted in the same accuracy,which would be beneficial to the scientific mansgement of soil and water conservation. |
