英文摘要Soil microorganisms play an important role in regulating subsurface ecological processes. Planted woodland and natural grass vegetation are the main vegetation restoration strategies for preventing soil erosion on the Loess Plateau of China. However, the response of soil microbial community and diversity to planted woodland and natural grass vegetation is largely unknown in this region. Here, we investigated soil microbial community and diversity using high-throughput sequencing approaches in planted woodland and natural grass vegetation. We found a disproportionate influence of planted woodland and natural grass vegetation on soil microbial diversity, and there was an increase of soil fungal diversity and a decrease of soil bacterial diversity in planted woodland. Both soil pH and soil organic carbon (SOC) were highly related to soil microbial diversity in planted woodland and natural grass vegetation. Moreover, we found the complex interaction networks of soil fungal community in planted woodland. Meanwhile, there were the higher total path coefficients of soil fungal diversity and the lower total path coefficients of bacterial diversity in planted woodland according to SEM (structural equation modeling). Besides, planted woodland explained more variation to soil fungal diversity and natural grass vegetation explained more variation to soil bacterial diversity, indicating that soil fungal diversity was more easily affected by planted woodland, while soil bacterial diversity was more easily affected by natural grass vegetation. To enhance the balance of soil microbial diversity, we suggested that both planted woodland and natural grass vegetation are needed in this region, highlighting the necessity of understanding soil microbial ecology to manage vegetation restoration on the Loess Plateau of China. © 2019 Elsevier B.V.
