［Objective］Exploring the characteristics of slope erosion on typical lateritic slope farmland in northern Guangdong is of great significance for local soil and water conservation and sustainable agricultural development. ［Methods］Taking the lateritic soil from slope farmland in the Nanxiong basin of northern Guangdong as the research object，the characteristics of runoff and sediment yield on the lateritic slope under individual rainfall events were analyzed based on artificially simulated rainfall experiments with three slope gradients（5°，10° and 15°）and five rainfall intensities（80，90，100，110 and 120 mm/h）.［Results］1）The initial runoff time of a gentler lateritic slope（5°）was 2-10 s longer than that of a steeper slope（10°，15°），and the influence of rainfall intensity on the initial runoff time was greater than that of slope gradient. 2）The runoff of steeper slopes was greater than that of gentler slope. The slope runoff of the three different slopes and five different rainfall intensities ranged from 22.86 to 34.78 L. The impact of rainfall intensity on slope runoff was greater than that of slope gradient. 3）The sediment yield rate of lateritic slope was relatively high at the early stage of runoff，and then tended to fluctuate and stabilize. Under the same slope gradient，the greater the rainfall intensity，the greater the sediment yield of slope erosion；under the same rainfall intensity，the greater the slope gradient，the greater the sediment yield. The maximum sediment yield occurred at the actual rainfall intensity of 119.5 mm/h and a slope gradient of 15°. 4）The sediment yield of lateritic slope was influenced by rainfall，rainfall intensity，runoff，and slope gradient，and the sediment yield was significantly positively correlated with runoff and rainfall，with a coefficient of determination （R²）above 0.56.［Conclusion］The initial runoff time on lateritic slope farmland is related with rainfall intensity and slope gradient，decreasing with increasing rainfall intensity and slope gradient. Both slope runoff and sediment yield increase with the increase of slope gradient and rainfall intensity. The relationships between slope sediment yield and runoff，rainfall，and rainfall intensity can be fitted using linear or quadratic function equations，with high coefficients of determination.
