摘要
较详尽地介绍了降雨侵蚀力因子的各种算法,并通过在流失量监测中的应用作了选用分析。结果表明,已有算法均存有一定的局限性,而以新算法适用范围较广、监测精度较高和简便实用。
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.
