Yuncheng Salt Lake located in the southwest of Shanxi Province is one of the three major sodium sulfate inland salt lakes in the world, harboring rich microbial resources, while there is still a lack of systematic research on the archaeal diversity in this salt lake. Objective To explore the diversity of archaea in soil sediments of Yuncheng Salt Lake and analyze the influences of environmental factors on the diversity. Methods Soil physical and chemical analysis was carried out on 54 samples from 18 sampling sites in Yuncheng Salt Lake, and the effects of environmental factors on the archaeal diversity were analyzed by amplicon high-throughput sequencing. Results Amplicon analysis showed that Halobacteriota, Thermoproteota, Nanobdellota, Thermoplasmatota, and Asgardarchaeota were the main taxa. Among them, Halobacteriota and Thermoproteota were the dominant groups of archaea in the soil sediments of Yuncheng Salt Lake. The analysis of diversity and community composition showed that there were obvious differences in archaeal communities among different sampling sites. Redundancy analysis showed that total nitrogen, total carbon, ammonium nitrogen, and SO42- had the greatest effect on the archaeal diversity in soil sediments, followed by nitrate nitrogen, Cl-, Mg2+, and Na+, while Ca2+, total phosphorus, and total potassium had mild effects. Conclusion The archaeal community in soil sediments of Yuncheng Salt Lake has high diversity and is closely related to environmental factors. This study enriches the biological information of archaeal resources in soil sediments of Yuncheng Salt Lake and provides a theoretical basis for the mining and research of archaeal resources in salt lakes.
