Abstract: As a mutual symbiosis formed between plants and soil mycorrhiza fungi, Mycorrhiza plays a key role in protecting host plants against environmental stress. Red mud is the high alkaline tailings from the production process of alumina, the tailing dam of red mud has adverse environmental impacts and its vegetation construction can be very difficult. This paper discusses the role of mycorrhiza and its application in the soil remediation in mining areas, and also the technological strategies of applying mycorrhiza in vegetation restoration of red mud tailing dam. It is concluded that applying mycorrhiza technologies to the vegetation construction of red mud tailing dam is feasible through extensive investigation and selection testing of mycorrhiza fungi and its suitable plants.

Key words: Mycorrhizas, Vegetation restoration, Tailing dam of red mud
