Abstract:

Arbuscular mycorrhizal fungi (AMF) can form a mutually beneficial symbiosis with more than 80% of plant roots on earth and play an important role in arable land resource conservation, vegetation diversity restoration, land desertification control, soil erosion control, and nutrient recycling. The low vegetation coverage near the surface of the understory erosion soil in the red soil areas of south China, coupled with the destruction of forest vegetation by human activities and the higher concentration of heavy rainfall, have caused serious understory soil erosion, which could reduce the productivity of forest land, bring serious harm to the ecological environment, and hinder the sustainable development of forestry industry and social economy in China. Understory inoculation with AMF can promote vegetation recovery and improve soil quality, which in turn can improve soil erosion resistance and reduce soil erosion. This study outlines the research progress of the restoration effect of AMF on vegetation and soil and water conservation in poor understory erosion land in south China, and discusses future research direction of AMF, aiming to provide a theoretical basis for vegetation restoration and soil erosion reduction.

Key words: AMF, poor understory erosion land, vegetation restoration, soil and water conservation, soil erosion
