| 摘 要： | 通过运用Visual MODFLOW软件对多年后研究区稀土元素在不同季节的运移范围进行预测,由此推测稀土元素的年平均迁移速度,对仅预测一个季节的研究作出补充。模拟结果表明:La元素的年平均迁移速度为61.97m/a,Ce元素的年平均迁移速度为46.24m/a,稀土总量的年平均迁移速度为56.07m/a。变化规律表明稀土元素浓度随距离的增加而降低,但稀土元素随着时间的推移进一步迁移。

| Abstract: | Visual MODFLOW software was used to predict the migration range of rare earth elements in the study area in different seasons many years later. The average annual migration rate of rare earth elements is inferred, and it supplementsthe previous research that predicted only one season. The simulation results show that the average annual migration velocity of La element is 61.97 m/year, the average annual migration velocity of Ce element is 46.24 m/year, and the average annual migration velocity of rare earth was 56.07 m/year. The change law indicates that the concentration of rare earth elements decreases with the increase of distance, but the rare earth elements will further migrate over time. |
