To evaluate the change trends of plankton in inland saline–alkaline water bodies, this study investigated ecological restoration and rational development lakes northwest China. From June to October 2023, phytoplankton communities a high-salinity lake Alar City, Xinjiang, were analyzed using standard survey methods for natural waters. Biodiversity indices calculated, redundancy analysis (RDA), Spearman’s correlation analysis, Mantel test carried out assess functional community structure its environmental drivers. In total, 115 taxa belonging seven phyla identified. The densities ranged from 23.76 × 105 53.54 107 cells/L. Bacillariophyta Cyanophyta dominant phyla, accounting 41.7% 27.8% total taxa, respectively. species included Microcystis spp., Merismopedia sp., Cyclotella meneghiniana, other algae. Spearman revealed that salinity, temperature (WT), Na+, TDS, HCO3−, Cl−, K+ key factors significantly influencing structure. tests confirmed salinity (SAL), DO, major ions (K+, CO32−) served as determinants spatiotemporal distribution (p < 0.05). RDA results indicated WT, alkalinity (ALK), pH, Na+ driving seasonal variations communities. Notably, decreasing ion concentrations stabilized structure, maintaining high-diversity indices. This highlights positive impact measures, such fisheries-based control systematic management, on health ecosystems. These findings provide important insights sustainable fisheries conservation aquatic biodiversity arid regions.
