Abstract:In order to explore the effects of different microtopographic characteristics on splash erosion, so as to provide scientific basis for soil and water conservation tillage in the Loess Plateau, the Yangling Lou soil was taken as the research object. Through indoor artificial simulation rainfall experiment (rainfall intensity was 20 mm/h, 40 mm/h, 60 mm/h, 80 mm/h, 100 mm/h, 120 mm/h, respectively, lasting for 10 min), the influence of microtopographic units caused by different tillage measures (land leveling, dibble sowing, drill sowing) on splash erosion were studied. The results showed that:(1) Under different slope conditions (0, 6°, 10°, 13°, 20°, 26°), the total amount of splash erosion in cultivated microtopographic unit increased linearly with the increases of rainfall intensities (R2 ≥ 0.95). (2) The amount of splash erosion on the downward slope in the microtopographic unit was a bivariate linear function with the changes of slope and rainfall intensities (R2 ≥ 0.90). (3) The micro slope direction in the cultivated micro terrain unit would affect the direction and distribution of splash erosion. The research results could provide a reference for revealing the causes of splash corrosion and perfecting the splash corrosion mechanism.
