| 英文摘要 | Carbon (C) and silicon (Si) are essential lake ecosystem components, impacting both phy-toplankton growth and other available elements and nutrients. In this study, we selected a typical floodplain-lake system to explore the seasonal role of coupled C and Si as mat-ter is imported and exported through lotic water processes. Results showed considerably higher dissolved inorganic carbon (DIC), dissolved organic carbon (DOC), and dissolved to-tal carbon (DTC) concentrations during the transitional stage between the dry and wet season (here referred to as TDW) compared to the other seasonal stages (5.81 mg/L-28.80 mg/L), indicating that imported runoff significantly effects the transport of C and Si. Rock weathering was the main source of dissolved silicon (DSi). The dilution effect and water temperature may also impact DIC, DOC, and DTC concentrations. Except for the wet sea-son, Bacillariophyta was the dominant phytoplankton taxon, and diatom growth as well as the growth of other algae taxon may influence DSi and DTC concentrations through sev-eral biochemical processes. This study describes effects of coupled C and Si and highlights variation in environmental variables driven by the resident phytoplankton communities in a lake ecosystem.(c) 2022 European Regional Centre for Ecohydrology of the Polish Academy of Sciences.
