Abstract: The objective was to research soil types (lime soil and yellow soil) and plant species (Celtis biondii Pamp,Castanopsis hystrix, Kmeria septentrionalis Dandy) effect on the community structure of AM fungi by morphology, topromote vegetation recovery in degraded land of karst. A total of 14 AM fungi belonging to 2 genera were found basedon spore morphology, of which G. etunicatum was dominant species in both lime soil and yellow soil. Five AM fungal: G. geosporum, G. albidum, G. ambisporum, G. eburneum and G. scrobiculata species occurred only in lime soil. In contrast, A. undulata was only found in the yellow soil. Soil type significantly affected spore density, Shannon diversityindex and colonization of AM fungi. Shannon diversity index of AM fungi was correlated with plant species. There was a significant difference between AM fungal composition structure in different rhizosphere soils. The spore density of AMfungi in lime soil was higher than that in the same rhizosphere in the yellow soil, except Castanopsis hystrix. Both the AM fungal species richness and Shannon diversity index, in rhizosphere soil of Celtis biondii Pamp and Castanopsis hystrix, were significantly higher than in the yellow soil. Soil type significantly affected AM fungal spore density, species richness, Shannon diversity index and colonization. Evenness was significantly correlated with soil type. Furthermore, plant species had a effect on the AM fungal Shannon diversity index. The interaction between soil type and plant species affected AM fungal species richness, Shannon diversity index and colonization. Soil pH and total potassium content showed a significant influence on the AM fungal community structure. Therefore, we should take into account specific region and host plantspreference before utilizing AM fungi to promote planting and recovery in the karst region.
