This study selected daily precipitation data of 57 main meteorological stations from 1956 to 2013in Fujian province to calculate rainfall erosivity by applying the daily rainfall erosivity model and analyze the impact of ENSO events on rainfall erosivity in Fujian province.The results indicated that although the impacts of ENSO on meteorological stations were different in different areas,there were some general rules as follows:(1)The trend of rainfall erosivity showed general upward but an evident inter-annual and intra-annual variation;(2)Rainfall erosoivity was significantly related to SST anomaly in equatorial Pacific.The rainfall erosivty during El Nio period was relatively higher than that during the La Nia period,but they were both lower than the average rainfall erosivty in Fujian province;(3)There were extremely significant correlation between rainfall erosivity and SOI and MEI.Through analyzing the effect of ENSO on rainfall erosivity,it would provide reference and basis for soil erosion prediction of and soil conservation in Fujian province.
