The diversity and community composition of archaea in soil samples from three wetlands (SP1, SP2, and SP3) of Ebinur Lake were studied by constructing 16S rDNA cloning library. The correlation between the diversity of archaea and soil environmental factors was analyzed by CANOCO software. The aim of this study was to reveal the differences of community structures of archaea in different sample sites, to provide a theoretical basis for further study on degradation and restoration of Ebinur Lake wetland. The results showed that Euryarchaeota accounted for 57.1% was the most dominant phylum observed, followed by Thaumarchaeota and Crenarchaeota for the three wetland soil analyzed. Compared with SP3 site, the proportions of Euryarchaeota were decreased by 16.70% and 31.78%, while Thaumarchaeota increased by 7.26% and 17.64% in the SP1 and SP2, respectively. Crenarchaeota was found only in SP3. Shannon-wiener diversity indices in SP1, SP2, and SP3 sites were 3.44, 3.87, and 3.94, respectively, indicating that the diversity of archaea in three plots was: SP3 > SP2 > SP1. Redundancy analysis (RDA) showed that electrical conductivity (EC), soil moisture (SM), hydrogen potential (pH), and soil organic matter content (SOM) may affect archaeal communities. Compared to EC and pH, SM and SOM may have a greater impact on the community composition of archaea.
