摘要
概述了点、地块、坡面、流域、区域等不同尺度域侵蚀模数的物理概念和数学表达式,分析了其相关关系;介绍了不同尺度域侵蚀模数的测定和计算模型,对今后侵蚀产沙的监测研究工作提出了建议。
Physical concepts of the ＂soil erosion rates＂ in different scales, such as erosion rate for a point, for an erosion block of land, for a slope, for a catchment and for a region, and their relevant formula were given. Meanwhile, monitoring methods and calculating models for assessments of those rates were introduced. Suggestions for future monitoring and research works on soil erosion and sediment production were also proposed.
