摘要：

The BCR continuous extraction method was used to extract soil samples from a uranium mining area in northern Guangdong, and the RSP and RAC evaluation methods were used to evaluate the ecological risk of soil contamination elements in the study area. The results showed that the soil was mainly in the residue state, but Mn was mainly in the reducible state (33.51%) and weakly acidic extractable (28.41%), and U was mainly in the oxidizable state (43.16%) and weakly acidic extractable (31.23%). U and Mn were the main contaminating elements in the study area, with high potential ecological risk.
