Abstract：Through three-dimensional sampling analysis, one of Jiangxi uranium ore field downstream paddy soil uranium content was measured. The results show that the uranium content in surface soil ranged from 1.34 to 13.39 μg·g-1; using surfer software for visual mapping of uranium content in the block soil, rendering changes in figuring four groups profile of uranium content, and it showed negative correlation with the distance from the mine; uranium content was influenced by some interference, but still visible in the origin drawing software in the maximum depths of 40cm, reached more than 10μg·g-1, which may be related to plant adsorption, migration of nuclides. Through the evaluation of soil comprehensive pollution index, it can be proved that this area is in mild pollution. According to the above analysis, the leakage of waste water in the tailings reservoir of uranium mine is the main cause of these phenomena. In addition, the analysis of uranium concentration is based on the ICP-OES data, which is an important way to guide the monitoring and evaluation of the environment.
