Abstract：To elucidate the spatiotemporal distribution characteristics of metazoan zooplankton community and their relationship with environmental factors in the main stem and major tributaries of the Chishui River section in Renhuai City, the species composition and abundances of metazoan zooplankton were analyzed, and key environmental factors including water temperature, dissolved oxygen, pH, and turbidity were measured at 28 sites in the main stem and major tributaries in the Chishui River section in Renhuai City in field surveys conducted in January (winter), April (spring), July (summer), and October (autumn) 2023. The relationship between the species and abundances of metazoan zooplankton and quantified, and water quality was assessed by the diversity index (H′), evenness index (J), and richness index (D) and spatiotemporal differences and environmental driving factors were analyzed by statistical analyses. A total of 75 species of metazoan zooplankton belonging to 48 genera were identified, including 41 rotifer species (22 genera), 21 cladocera species (16 genera), and 13 copepod species (10 genera). Among the 10 dominant species, Bosmina longirostris and Mesocyclops leuckarti were perennial dominants with zooplankton abundance (3 189.72—19 318.54 ind./L) and biomass (19.47—43.24 mg/L) peaked in spring. Spatially, there was the maximal abundance in Wucha River and minimum in Chishui River, whereas the maximal biomass in Tongzi River and the minimum in Jinxi River. Diversity analysis revealed that the surveyed area was in light to moderate pollution levels overall, with significant spatiotemporal variations in H′, J′, and D: the maximal H′ and J′ in winter and the minimal in summer, while higher D were in spring and winter than that in summer and autumn. The best index (H′=2.03, J′=0.69, D=2.24, light-moderate pollution) was found in Tongzi River, and the worst conditions (H′=0.17, J′=0.25, D=0.04, moderate-heavy pollution) in Jinxi River. There were significant differences in H′ and D among rivers (P<0.05), without significant seasonal variations in any of the three indices (P>0.05). Environmental factor analysis indicated that pH, turbidity, water depth, transparency, electrical conductivity, and total dissolved solids were shown to be the primary drivers of community structure, and water temperature and dissolved oxygen being secondary factors. The finding provides important scientific references with the ecosystem health assessment and ecological restoration in the main stem and tributaries of the Chishui River section in Renhuai City.
