Understanding biodiversity is essential for preserving the stability of river ecosystems. However, impact landscape configurations and seasonal variations on within undammed ecosystems remains unexplored. Therefore, we selected Chishui River-a naturally flowing tributary upper Yangtze River-for a survey periphytic algae. The present study focuses fluctuations in β-diversity algae River its correlation with surrounding patterns. Our findings indicate that there substantial influence community structure these ecosystem. Concurrently, observed turnover component predominantly contributes to β-diversity. In light findings, recommend conservation measures be implemented across entire basin safeguard regional biodiversity. Redundancy analysis elucidated water temperature, conductivity, pH were primary environmental drivers shaping algal communities. Furthermore, additional analyses using random forest model indicated fragmentation complexity key determinants Notably, number patches was strongly correlated It important highlight maintaining an optimal balance between their size crucial enhancing ecosystem's capacity preserve summary, our provide insights into interplay land-use practices complex riverine environments, thereby offering scientific foundation management
