Straw mulching is a key method for controlling soil and water losses. Mulching costs may be reduced by applying it in strips rather than over entire areas. However, the effect of different straw methods on effectiveness reducing erosion unclear. In this study, effects strip length (covering 1/4, 1/2, 3/4, 4/4 slope length) coverage rate (0.2, 0.5, 0.8 kg m−2) interception, infiltration, runoff, were investigated at plot scale using rainfall simulation experiments. The further complex correlations between these variables analyzed structural equation modeling (SEM). Bare slopes used as control group. intensity was chosen to 60 mm h−1. results showed that (1) modified Merriam interception model can describe change with time under conditions well (R2 > 0.91, NSE 0.75). (2) A total 35.39–78.79% rainwater converted into infiltration straw-covered slopes, while proportion 36.75% bare slopes. greatest (78.79%) when covered 3/4 0.5 m−2, which most conducive harvesting slope. (3) protects topsoil from impact raindrops directly affects sediment yield (direct = −0.44). also indirectly affect increasing decreasing carrying capacity runoff (indirect −0.83). Compared covering least 1/2 significantly reduce yield, but only 1/4 yield. Moreover, once mulch reaches increases will not yields. These assessed losses sloping farmland.

Rainfall erosivity is a crucial factor in the evaluation of soil erosion, significantly influencing complex relationships among water, soil, and environment. Understanding its attributes variations space time essential for effective water resource management, erosion mitigation, land-use planning. This paper utilizes daily precipitation data from 123 grid points Niyang River Basin, spanning 2008 to 2016, calculate rainfall using straightforward algorithmic model. Ordinary Kriging was used examine spatial temporal erosivity, while Spearman’s correlation analysis employed between annual various factors, including multi-year average precipitation, erosive rainfall, dry-season wet-season temperature, elevation. The results indicate year-by-year increase basin, with trend towards stabilization. over years 711 MJ·mm·hm−2·h−1, peaking at 1098 MJ·mm·hm−2·h−1 2014. A significant 93.9% concentrated wet season, maximum 191 July. left bank mainstream, especially central lower sections main river tributaries, experiences highest erosivity. factors predominantly influence showing strongest (rho = 0.93), temperature elevation have relatively minor effects. study enhances understanding forces plateau region provides scientific basis predicting loss, developing control measures, ensuring sustainable land use.
