Rainfall patterns affect soil erosion on hillslope farmland in Northeast China's black soil region. Different rainfall intensities and timings can lead to varying levels of runoff and soil loss. Peak-type rainfall causes the highest runoff, while Reduced-type rainfall results in the most soil loss. The position of intense rainfall within a pattern influences runoff and soil erosion rates. Early heavy rainfall leads to higher soil loss, while mid or late-stage intense rainfall increases runoff. The Reduced-type rainfall pattern is most erosive in this region, causing severe soil erosion on hillslope farmland.
