- Abstract:
- Daily rainfall data from 5 typical meteorological stations from 1956 to 2015 in Jiangxi Province were used to study the characteristics of erosive rainfall and rainfall erosivity of each rainfall grade. A rainfall erosivity model using annual erosive rainfall of each rainfall grade to estimate annual rainfall erosivity was established. The results showed that the distributions of erosive rainfall, rainfall days, rainfall erosivity of each rainfall grade were different. With time increasing, rainfall of annual rainstorm, proportion of annual rainstorm, annual rainstorm days, annual rainstorm erosivity, and annual rainfall erosivity increased from south to north at different degrees. The simulated annual rainfall erosivity by using annual erosive rainfall of each rainfall grade was highly correlated with the accurate annual rainfall erosivity, and the model could be used to estimate annual rainfall in Jiangxi Province.
