[Objective] Studying the distribution pattern of rainfall erosivity in the southeastern area of Fujian Province to privide basis for soil erosion control and soil and water conservation plan.[Methods] Based on the data from 26 rainfall station in the Southeastern Fujian Province during 1980-2009
simple algorithm for rainfall erosivity was used.[Results] Rainfall erosivity in Southeastern Fujian Province showed a bimodal distribution as it occoured mainly from May to August. Rainfall erosivity varied greatly over years. The highest value was 725.39 (MJ·mm)/(hm2·h) occurred in 2006
while the lowest value was 253.82 (MJ·mm)/(hm2·h) occurred in 1982
with the extreme ratio of 2.86. Rainfall erosivity in Southeast Fujian Province during the past 30 years did not showed abrupt changes.[Conclusion] Rainfall erosivity showed an uneven distribution pattern with increasing trend from coast to inland
and the value was comparatively higher in southwest than that in northeast.
