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.
