本文介绍了USLE与RUSLE的主要区别,从分析比较可知,RUSLE比USLE有较大的改进,更符合模拟侵蚀过程的要求。目前推出RUSLE不是等待更完善的高级侵蚀预测模型(如WEPP)问世,而是基于USLE已有一定的侵蚀过程概念基础,其新的模型具有更复杂的结构和需要充分的试验数据的支持。RUSLE仍在发展中,它将以国际单位制出现,以便将使用的方法(RUSLE模型软件包)奉献于用户。对RUSLE模型的应用前景以及今后有希望应用的模型如WEPP,欧洲流失方程以及新近立项的MEDALUS模型的发展前景作了展望和比较分析。
This paper introduces the main differences between USLE and RUSLE. From the analysis and comparison, we can see that RUSLE has a lot more improvement than USLE, which is more in line with the requirements of simulation erosion process. RUSLE is not waiting for a better advanced erosion prediction model (such as WEPP) but is based on the notion that the USLE has a certain underlying concept of erosion process. Its new model has more complex structures and requires adequate experimental data support. RUSLE is still under development and will appear in the SI system in order to dedicate the method used (the RUSLE Model Package) to users. The prospect of the application of RUSLE model and the prospects of future applications such as WEPP, the European loss equation and the newly developed MEDALUS model are prospected and compared.
