[Objective]The temporal and spatial variation trend of rainfall erosivity in Jilin Province from 1961 to 2015 were analyzed to provide scientific bases for agricultural and ecological protection,as well as soil and water conservation.[Methods]Based on the daily rainfall data from 46 meteorological stations in Jilin Province from 1961 to 2015,rainfall erosivity was estimated and the temporal and spatial distribution was analyzed with correlation coefficient,climate tendency rate and the inverse distance interpolation methods,respectively. [Results]The spatial distribution of rainfall erosivity has a decreasing trend from the station of Jian to the northwest and northeast region.The spatial distribution of average annual rainfall erosivity is similar to that of average annual precipitation.The temporal distribution of yearly averaged rainfall erosivity is similar to that of multi-year average precipitation,which has a peak in July.34.8% meteorological stations have incline rainfall erosivity.For most of the western region,there is a downward trend;while for more than half of the stations in eastern region is on the rise,among with Changbai station was significant.The changes of average rainfall erosivity of each decade in different regions are not consistent,and have fluctuation. The spatial distribution of rainfall erosivity contour in different decade differ slightly.[Conclusion] Rainfall erosivity in Jilin Province is consistent with the precipitation in temporal and spatial variation,and the trend of rainfall erosivity in different regions is different,and almost dose not pass the significance test.
