Abstract: Periphytic algae in rivers are widely used to evaluate the impact of human disturbance on aquatic ecosystems. The community of periphytic algae and water quality were investigated from September 2021 to August 2022 in Xuhong River. Relationship between the characteristics of periphytic algae community and water environmental factors was discussed. The results showed that 58 species of algae were detected in Xuhong River, belonging to 42 genera of 3 phyla. The average density of periphytic algae was 1.17×106 cells/cm2, the average diversity index was 1.64, and the evenness index was 0.65. The density of algae was very significantly correlated with water temperature, dissolved oxygen, ammonia nitrogen and total phosphorus in the river. There was a significant positive correlation between the diversity of periphytic algae and permanganate index, and a very significant correlation with turbidity. Furthermore, the permanganate index content was the key factor to promote the succession of periphytic algae community structure.
