通过三维取样分析， 对江西某铀矿田下游水稻土壤铀含量进行测定， 结果表明表层土壤中铀含量介于134～1339 μg·g-1； 利用surfer软件， 对该区块土壤铀含量进行直观绘图， 绘制四组剖线铀含量变化图， 可见其与距矿山距离负相关； 经过翻耕的土壤铀含量变化受到一些干扰， 但在origin软件绘图中仍可见其在40 cm深处达到最大值， 均达到10 μg·g-1以上， 这可能与植物吸附， 核素迁移规律等有关。 经土壤综合污染指数评价， 该地区为轻度污染。 综合以上分析， 铀矿山尾矿库的废水渗漏是造成这些现象的主要原因。 其中， 铀浓度分析是建立在ICP-OES数据基础上的， 这是光谱学指导环境监测和评价的重要途径。

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.
