Structural Characteristics of Periphytic Algal Community and Its Relationship with Environmental Factors in the Taiyuan Region of the Fenhe River

In order to explore the characteristics of periphytic algae community structure and its relationship with environmental factors in Taiyuan region Fenhe River, a total six sampling sites were investigated July December 2021. The effects water quality status at each point on epiphytes detected. results showed that 7 phyla 54 genera identified species composition was mainly Bacillariophyta, Cyanophyta, Chlorophyta. According analysis biodiversity index, body River is state moderate pollution. correlation between epiphytic cell density significantly correlated dissolved oxygen (DO), phosphate (PO3− 4-P), chemical demand (COD), phosphorus (TP), transparency (SD) wet season. algal dry season temperature (WT), TP, PO3− 4-P, COD. redundancy analysis, distribution closely related physical such as COD, nitrate nitrogen (NO− 3-N), WT, organic carbon (DOC), (TN), COD main factor driving change TN control biological
