Evaluation of the Influence of Habitat Heterogeneity and Human Activities on the Distribution of Microbial Diversity in a High Elevation Drop River

The aim of this work was to investigate the microbial diversity characteristics and driving factors in a high elevation drop river analyze potential risks microorganisms human health. In March 2019, we analyzed surface water sludge from Huotong River using high-throughput sequencing. is great importance production life people living along river. sampling points were set at estuary river, on downstream section an upstream main one tributary flowing through town, with barrage, source tributary. results showed significant differences bacterial different areas For example, actinomycetes less abundant samples headwaters tributaries more upriver. revealed that intensities activities had effects functional flora. Anthropogenic disturbance reduced abundance probiotic bacteria increased pathogenic changes floral may pose threats
