秸秆覆盖可有效地降低累积径流量和总侵蚀量，增加累积入渗量；
Straw covering could decreased cumulated runoff and sediment and increased infiltration in the same time.
按此标准，可剔除降雨场次50%以上，而漏选的土壤流失量占总侵蚀量的比例在3%以内。
According to that standard, 50% of the number of rainfall can be eliminated and soil erosion volume which failed to choose takes up 3% of total erosion amount.
细沟的宽度和深度随雨强的增大而增大，产生细沟后侵蚀量将迅速增大，最大占总侵蚀量的91%。
Rill width and depth become bigger with rainfall intensity, erosion amount promptly enhances after rill appears, accounts for 91%.
