英文摘要	Soil microbial communities maintain multiple ecosystem functions in terrestrial ecosystems. The response of soil microbial communities to vegetation restoration in desertification environments is still poorly understood. Therefore, the purpose of our study was to evaluate the dynamic changes of the soil microbial community during the growth of Pinus sylvestris var. mongolic (P. sylvestris) plantations. We collected soil samples from five P. sylvestris plantations with different stand age. High-throughput sequencing was performed to determine the microbial community structure. The dynamic relationship between soil microbial community and edaphic factors was analyzed using the co-occurrence network, mantel test and partial least squares path modeling. The results showed that the soil microbial alpha diversity and community structure were significantly various among the plantations (P < 0.001). The number of nodes and edges in microbial co-occurrence network gradually decreased and the interrelationships between species became weak with stand age. The Available phosphorus was the most significant factor affecting the structure of bacterial community (R2 = 0.952), while the total phosphorus was the most significant factor affecting the structure of fungal community (R2 = 0.745). However, soil moisture had no significant effect on the microbial community. pH (0.73) and available nitrogen (0.91) had the largest positive total effects on bacterial and fungal community, respectively. Stand age (-0.65) was an indirect factor with the largest negative total effects on the bacterial community. Therefore, we concluded that the soil microbial community was not limited by soil moisture during the natural restoration process of P. sylvestris plantations in the desertification environment and the phosphorus utilization efficiency played a leading role in shaping the soil microbial community.
