ABSTRACT=nutrient availability correlated with keystone bacteria, and changes in nitrogen content could be attributed to nitrogen mineralization. This indicates that fluctuations in the groundwater table play a role in regulating microbes and the distribution of soil carbon and nitrogen nutrients in arid environments. Consequently, maintaining a GTD within a reasonable range is imperative for ecological restoration in arid regions. Preserving an appropriate ecological groundwater depth is essential to mitigate sandy vegetation degradation and enhance soil fertility accumulation.
