- Abstract
In this paper, managed forest ( MF) and natural forest ( NF) in the Huajiang Demonstration Zone of Guanling, Guizhou were selected as research objects, and cropland ( CL) was taken as control. High-throughput sequencing technology was used to study the characteristics of fungal community composition and species diversity in the surface ( 0 - 10 cm) soil of each restoration measure, in order to reveal the dominant soil fungal groups and fungal community composition in karst rocky desertification areas, which was conducive to a more comprehensive understanding of the soil conditions of different vegetation restoration measures. Research has shown that vegetation restoration significantly affected the diversity of soil fungal community, with significant increases in Sob index, Ace index, and Chao index. The vegetation restoration has significantly changed the composition of fungal community. The dominant fungi in the CL topsoil are Sordariomycetes (62. 28%), Dothideomycetes (12. 34%), and Eurotiomycetes (9. 12%); the dominant fungi in the MF soil are Sordariomycetes ( 45. 05%), Dothideomycetes ( 14. 74%), and Mortierellomycetes ( 10. 40%) ; the dominant fungi in the NF soil are unclassified fungal community (26. 38%), Sordariomycetes ( 19. 78%), and Agaricomycetes ( 13. 82%). Vegetation restoration has changed the key fungal groups in the soil. Sordariomycetes, Fwarium, and Setophoma are the key dominant fungal groups in CL soil; Dioszegia is key dominant fungal group in MF soil; c_unclassified_k_Fungi, p_unclassified_k_Fungi, o_unclassified_k_Fungi, f_unclassified_k_Fungi, g_unclassified_k_Fungi, Teichospora, and Diaporthe are key dominant fungal groups in NF soil.
