Abstract:: Through the obtained materials of 1997 to 2003 in the Ecological Experiment Station of Red Soil (EESRS), Yingtan, Jiangxi Province, the rainfall erosivity (R) and its characteristic under different rainfall intensity were significantly remarkable and the tendency of mean rainfall erosivity (R) was: I₁₀>I₁₅>I₃₀>I₆₀. They all demonstrated that it was critical to establish a suitable rainfall intensity calculating R to improve the precision of prediction model of soil erosion in the area of Yingtan. Through analysis of soil loss and index R of rainfall erosivity, I₁₅ was the best in the rainfall erosivity in the area of Yingtan.
