| 摘 要： | 对铀尾矿生长的夹竹桃、狗芽根、假俭草和蕨及土壤中的U、^226Ra的含量进行了测定。结果表明，夹竹桃、狍芽根、假检草和蕨对U、^226Ra具有一定的积累，并且植物体地上部分U、6226Ra的含量小于地下部分U、^226Ra的含量；四种植物为铀尾矿的耐性植物，可用于尾矿地的生态恢复。

| Abstract: | This study was conducted to determine concentrations of uranium and radium of Pteridium aquilinum, Nerium indicum ,Cynodon dactylon and Eremochloa ophiuroides growing in uranium tailing area. The results showed that uranium and radium could accumulated by Pteridium Aquilinum, Nerium indicum ,Cynodon dactylon ,Eremochloa ophiuroides . Concentrations of uranium and radium in parts of plants on the ground were less than that under the ground. The results indicated that these species were tolerant plant and would be revegetated in uranium tailing area and abandoned mine. |
