In response to cutting-edge scientific questions related to the carbon and nitrogen cycle in saline lakes, the authors conducted a comprehensive study on the impact mechanism and environmental effects of climate and environmental changes such as increased organic matter input, increased temperature, and reduced salinity on the microbial activity of the carbon and nitrogen cycles in saline lakes, and obtained a series of research findings. Finally, a summary of the microbial effects on carbon and nitrogen cycling in lakes is presented, and prospects for future development directions are proposed.
