Abstract:

Shrubs are the main plant forms in arid desert areas and play an important role in maintaining biodiversity and ecological functions in these areas. We utilized high-throughput sequencing technology to analyze the soil bacterial diversity of six typical desert plant communities in the desert areas to the north of the Yinshan Mountains: Reaumuria songarica, Nitraria tangutorum, Ammopiptanthus mongolicus, Brachanthemum mongolicum, Kalidium foliatum, and Haloxylon ammodendron. The results showed the following: (1) The dominant phyla of soil bacteria in the six vegetation communities were Actinobacteria and Proteobacteria. (2) The Shannon diversity index of bacteria is sensitive to environmental changes. The higher the Shannon index, the better the soil nutrient status. (3) Soil moisture content, mechanical composition, pH value, electrical conductivity, and vegetation type are all factors that significantly drive the composition of the bacterial community structure.
