[Background] Rainfall erosivity is for assessing the potential ability of rainfall on soil erosion.A regional soil erosion prevention and controlling work have a guiding significance.Water erosion is one of the important forms of soil erosion in Fujian province.[Methods] To study the spacetime distribution of West Fujian rainfall erosivity pattern,based on the 1980-2013 daily rainfall data of nine weather stations in West Fujian region and using the Daily Rainfall Erosion Force Model to calculate the rainfa...
