Jiangxi province is a typical place with soil erosion in the hilly red soil regions of Southern China.Soil erosion is serious.In this paper，CSLE model is used to quantitatively evaluate soil erosion and its spatial distribution in Jiangxi province at regional scale.The research shows：（1）In 2019，the total soil erosion area of Jiangxi province is 24 151.18km2，accounting for 14.46% of the total area of the province；（2）The soil erosion in Jiangxi province is mainly mild erosion，accounting for 13.18% of the total land area of the province；（3）The erosion area of grassland is 666.46km2，accounting for 29.26% of the grassland area；the erosion area of garden land is 1011.67km2，accounting for 19.18% of the garden area；the erosion area of woodland is 19 089.21km2，accounting for 18.07% of the total forest land area，and mainly mild erosion.
