| Abstract: | The various algorithms of erosivity factor of rainfall are introduced and the results of applicating in monitoring soil loss are discussed. Those show that the existent algorithms exist some limitations and the new algoritm have wider suitability, higher monitoring accuracy and more convenient calculation. The unit of R factor value must be in according with K factor value of soil erodibility and the R factor value must be selected one of monitoring year in monitory of soil loss by remote sensing, etc. |
