Abstract :This study aimed to analyze the characteristics of
soil microbial communities of Hippophae rhamnoides forest during
the revegetation of abandoned cropland in the Loess Plateau in China. We
used high-throughput sequencing technology to analyze the carbon (C) and
nitrogen (N) characteristics of soil microorganisms and the relationship
between the soil environment and the soil microbial community structure
in pure and mixed Hippophae rhamnoides forests in Wuqi County,
Shaanxi province. The findings revealed that soil microbial C and N in
different soil layers showed a decreasing trend with an increase in soil
layers and the structural difference of the soil microbial community
among different forest stands in the study area was smaller than that
among different soil layers. Gracilibacteria, Gemmatimonadetes,
Nitrospirae, Parcubacteria, and Actinonobacteria in bacteria were
significantly correlated with soil environmental factors. Ichthyosporea
and Ciliophora in fungi were strongly affected by environmental factors.
The effect of environmental factors on bacteria is greater than that on
fungi. Our findings can provide some data to support and feasible
suggestions for studies on revegetation in the Loess Plateau.
