[Objective] To study the effects of crop vegetation on the prevention and control of soil erosion in order to provide crop parameters to establish erosion prediction model for the laterite area.[Methods] Through the artificial rainfall simulation experiment, throughfall, stemflow and canopy interception were measured in different growth stages of sugarcane and different rainfall intensity conditions, and leaf area index for the effects of rainfall redistribution were analyzed.[Results] The throughfall, stemflow and canopy interception changed from 94.7%, 5.1% and 0.3% in the sugarcane seedling stage to 49.4%, 47.3% and 3.4% in the mature stage, respectively. [Conclusion] The sugarcane leaf area index had a significant negative linear correlation with throughfall, and a significantly positive linear correlation with the stemflow and canopy interception.
