Abstract: The roles of mycorrhizae and its response to the desertification,as well as its application in desertification land restoration were discussed in this paper.It is suggested that mycorrhizae can not only promote the nutrient absorption,improve photosynthesis rate,and enhance the drought and salinity resistance,but also can adjust to the relationship among plants,succession trajectories and biodiversity in community.Human activities including tillage,overgrazing,and mining can not only cause land desertification,but also impact negatively on the persistence and establishment of mycorrhizae.Introduction of exotic mycorrhizal fungi and culture of remnant of native,establishment of brush with mycorrhizae in clump,mycorrhizalization seedling in afforestation,and storage of surface soil should be carried out in order to speed up the desertification land restoration.
