在农业生产中,防止土壤侵蚀是环境保护最重要的问题之一。在苏联,受侵蚀危害的土地约占整个土地面积的66％。其中约57％需要防止春天径流的侵蚀,33％需要防止解冻径流和大雨径流的侵蚀,10％需要防止暴雨的侵蚀。 大雨的侵蚀遍及地球大部分地区。不仅在融雪时,而且在下大雨时,土壤表层也遭到严重破坏。这样,实际上使得研究侵蚀过程的机制和强度更加复杂。特别使制定防止土壤侵蚀的 In agricultural production, preventing soil erosion is one of the most important issues in environmental protection. In the Soviet Union, the land harmed by erosion accounts for about 66% of the total land area. About 57% need to prevent spring runoff erosion, 33% need to prevent thawing runoff and heavy rain runoff erosion, and 10% need to prevent heavy rain erosion. Heavy rains have eroded over much of the planet. The soil surface was also severely damaged not only during snowmelt but also during heavy rains. In this way, the mechanism and intensity of the study of the erosion process are actually more complicated. Special enactment to prevent soil erosion
