To explore how environmental factors affect the structure of plankton in urban rivers, we analyzed Caowangjing River, an river that passes through Wuxi, to survey water and population different seasons. We identified 103 phytoplankton species belonging eight phyla, with Chlorophyta, Bacillariophyta, Cyanobacteria being dominant groups. A total 45 zooplankton belonged three classes, Rotifera class. Phytoplankton density was highest autumn, followed by spring, lowest summer. biomass, along exhibited seasonal declines. The average values Shannon–Wiener index, Pielou’s evenness Margalef richness index were 3.58 ± 0.50, 0.72 0.76, 2.03 0.31, respectively, indicating River mildly polluted based on a quality evaluation. Redundancy analysis showed turbidity, temperature, ammonia nitrogen are key community distribution, while permanganate distribution.
