Abstract: Arbuscular mycorrhizal fungi (AMF) are a sort of microbe which could form mutualistic symbionts with most of the terrestrial plant roots. Recently, the mycorrhizal symbiosis system dominated by AMF has been a new subject of bioremediation, which could significantly enhance the success rates and shorten the cycle in the restore process of degraded ecosystem, and ensure the stability of restored result. Karst rocky desertification is a critical environmental problem which could restrict the sustainable development of karst regions in Southwest China. The characteristic eco-physiological functions of AMF have good corresponding relations with the urgent obstacles in karst rocky desertification control, which makes AMF possess important potential application value in this restore process. The paper summarized the eco-physiological functions of AMF and discussed the availability and application way of AMF in karst rocky desertification control. This study aims at studying the adaptation measure of karst plants and laying a theoretical basis for karst ecosystem degradation and restoration, and finally finding a new effective practical way for karst rocky desertification control and sustainable development of ecological economy.
Key words: AMF; karst rocky desertification control; application
