| 中文摘要 |
| 随着人们对新能源需求的增加及核能的不断开发利用，放射性核素污染问题日趋严重. 由于各种原因导致的放射性核素铀(U)制品及相关废弃物的排放，对土壤和水体造成严重污染，并最终威胁到环境安全和人类健康. 另一方面，作为一种环境友好的生物技术，近年来菌根修复技术在污染环境治理方面的可能应用得到越来越多的关注. 本文在概述放射性核素U及其环境危害的基础上，着重介绍了丛枝菌根对于植物吸收累积U的影响极其机制，探讨菌根技术修复U污染土壤的可能应用途径及范围，并提出将来的研究方向. |
| 英文摘要 |
| With the increasing demand for new energy,nuclear industry has been developing very fast,and uranium (U) pollution becomes a serious environmental problem especially in the mining area.The discharge of U products and wastes can contaminate soil and water,and finally threaten human health.On the other side,as an environment-friendly biotechnology,the importance of mycorrhizal technology in remediation of polluted environments has received much attention in recent years.Following a brief introduction of the environmental impacts of U contamination,this review summarized the effects of arbuscular mycorrhiza (AM) on U uptake and accumulation by plants based on recent research progresses,suggested possible application of AM fungi in remediation of U contaminated environment,and finally discussed about the perspectives in relevant research area. |
