Abstract: Arbuscular Mycorrhizal Fungi (AM fungi) has potential applications in the ecological restoration of karst areas. Recently, the diversity and ecological functions of AM fungi in karst areas have drawn increasing concerns. In order to provide supporting for selecting efficient ecological restoration strains in karst areas, a list of AM fungi isolated from karst area was summarized. The influence law on the diversity of AM fungi in karst area were reviewed from the perspectives of the calcareousness of soil, the lack of nutrients, the spatial heterogeneity of soil, the reverse succession of vegetation, the diversity of plant and other characteristics; the physiological and ecological function and mechanism of AM fungi on soil structure, nutrient cycle, plant drought resistance, plant nutrient absorption and vegetation succession in karst areas were summarized. This study aimed to provide guidance for the study on adaptability of AM fungi, the effective utilization of the potential ecological functions of AM fungi and the selection and cultivation of AM fungi-plant symbiosis system, and to provide theoretical basis for the application of mycorrhizal technology in the karst ecological restoration. Future studies should further explore the influence mechanism of AM fungi diversity, discuss the relationship between AM fungi and plant adaptability and strengthen the selection and cultivation of AM fungi-plant symbiosis systems.
