Climate change and eutrophication have significant impacts on aquatic ecosystems, with phytoplankton playing a critical role as primary producers. This study investigates the relationships between communities environmental meteorological factors in Wuliangsuhai Lake, representative ecosystem an arid cold region of China. Using data from 25 sampling sites (April–September 2023), generalized additive model (GAM) was employed to analyze water quality laboratory measurements. The results showed bimodal distribution density, peaks July (5.33 × 106 cells/L) August (14.90 cells/L). Green algae dominated spring, while cyanobacteria became dominant summer. GAM analysis revealed that temperature (TEMP) driver, explaining 20.7% deviance. When TEMP examined together other factors, explanatory ability significantly enhanced, finally, explained 57.10% also different species responded differently cyanophyta-dominant Pseudoalgae being more sensitive pH, whereas chlorophyta-dominant Chlorella affected by wind speed salinity. Cyanobacteria dominance, exacerbated warming, increases risks harmful blooms instability, highlighting need for mitigation strategies vulnerable freshwater ecosystems.
