Abstract:As one of the important factors affecting soil erosion, rainfall erosivity (R) is related to rainfall characteristics of amount, duration, intensity, and kinetic energy.Using the daily rainfall data of 25 meteorological stations in Jiangxi province from 1961 to 2019, we analyzed the spatial distribution and variation trends of rainfall erosivity in Jiangxi province via rainfall erosivity model, as well as Mann-Kendall correlation test, wavelet analysis and Kriging spatial interpolation.The results showed that the annual average rainfall and rainfall erosivity varied similarly in spatial distribution, which were gradually increased from southern Jiangxi to northern Jiangxi;the rainfall erosivity in spring and summer ranged from 3 000 to 6 000 MJ·mm·hm-2·h-1·a-1, which was significantly higher than that in autumn and winter, with the maximum rainfall erosivity occurring in spring;the average annual rainfall erosivity in Jiangxi decreased from north to south, which maximized in northern Jiangxi and followed by central Jiangxi then southern Jiangxi.The research shows that the rainfall-induced soil erosion was increasing in Jiangxi province, especially in spring and summer, and there were obvious differences in their spatial distribution.
