摘要： 随着金属矿藏的大量开采,重金属污染问题愈加严重。重金属的大量排放不但对大气、水、土壤环境等造成严重的污染,而且进入环境的重金属将参与食物链循环并最终在生物体内积累,不但破坏了生物体正常的生理代谢活动,而且严重危害着人体健康。迄今,人类已采取了多种方法对重金属污染进行治理,菌根技术因其特有的优越性,越来越受到世界各国的广泛关注和深入研究。总结了菌根菌对植物抵御重金属污染影响的研究成果,在此基础上,从菌根菌对植物抗重金属胁迫的直接和间接作用等方面阐述了菌根菌对植物抗重金属毒害能力的研究。

Abstract: With the large number of metallic mineral mining,heavy metal pollution has become even more serious.Large emissions of heavy metals not only pollute air,water,soil and environment causing seriously,and heavy metals that into the environment will participate in the food chain cycle,and eventually accumulate in organisms,not only destroy the normal physiological metabolic activity of living organisms,but also wreck human's health seriously.So far,the human adopted various methods to governance heavy metal pollution,Because of Mycorrhizal technology's proper superiority,the general concern and in-depth research have been given in the world. In this paper,based on a summary of relevant results of the impact of mycorrhizal fungi to plant resistance to heavy metals pollution,the direct effects and indirect effects of mycorrhizal fungi on plant resistance to heavy metal toxicity was reviewed.

Key words: Mycorrhiza, Repair, Heavy metals
