| 摘 要： | 【目的】探究尕斯库勒盐湖生态系统中邻近水体对湖泊微生物的贡献。【方法】采集尕斯库勒盐湖区湖水、沉积物以及邻近的泉水、河水和盐田的水样，对其进行地球化学分析；通过16S rRNA基因的Illumina MiSeq高通量测序分析样品的微生物群落组成。【结果】尕斯库勒盐湖区水体和沉积物中的优势门是变形菌门(Proteobacteria)、拟杆菌门(Bacteroidetes)、放线菌门(Actinobacteria)和广古菌门(Euryarchaeota)。盐度和pH是影响尕斯库勒盐湖区群落组成的最主要环境因素。邻近水体对湖泊水体和沉积物的贡献分别为12.94%和7.53%。【结论】邻近水体对尕斯库勒盐湖微生物群落的贡献有限。

| Abstract: | Objective] To explore the contributions of adjacent water bodies to the microbial communities in Gas Hure Salt Lake. Methods] We collected the water and sediment samples from Gas Hure Salt Lake and the water samples from adjacent springs, river, and saltern for the measurement of geochemical parameters. Illumina MiSeq high-throughput sequencing was employed to explore the microbial community composition. Results] Proteobacteria, Bacteroidetes, Actinobacteria, and Euryarchaeota were dominant phyla in the water and sediment samples of Gas Hure Salt Lake. Salinity and pH were the most influential factors driving the community composition in the survey region. The contribution rates of adjacent water bodies to the microbial communities in the water and sediment of Gas Hure Salt Lake were 12.94% and 7.53%, respectively. Conclusion] The external water bodies have limited contributions to the microbial communities of Gas Hure Salt Lake. |
