Based on the daily rainfall data of 47 meteorological sites in the northern and southern regions of Qinling mountains,the annual average rainfall erosivity of the northern and southern regions of Qinling mountains is calculated following the rainfall erosivity model proposed by ZHANG which was set up on the basis of daily rainfall. The spatiotemporal characteristics of rainfall erosivity of different rainfalls in the study are analyzed by adopting the climate trend rate, inverse distance weight interpolation and Mann-Mendal mutation test. It shows: (1)The annual average rainfall erosivity due to different rainfalls in the concerned area from 1960 to 2017 exhibits a decreasing feature from south to north. (2)The interannual changes of the annual average rainfall erosivity, the erosivity due to rainstorm and heavy rain in the past 58 years shows an increasing trend, which fails to be detected by mutations. The erosivity due to moderate rain shows a decreasing trend. The mutation occurred in 1972, it reached a significant value after 2007. The annual average rainfall erosivity and storm erosivity in the northern region of the Qinling mountains exhibits a downward trend, and the degree of interannual fluctuations is relatively large. However, these parameters in the southern regions of the Qinling mountains demonstrates an opposite trend. (3)The average annual rainfall erosivity in the study shows a significant spatial variation. The obvious growth areas are concentrated in the Hanzhong basin and the Bawu valley. The reduction areas are concentrated in the western Jialing River, the junction of the Fen River and the Yellow River, as well as the two lake plains. The size of the area where the erosivity showed a growth trend presents a correspondence with the amount of the rainfall: ${
