| 英文摘要 | Trophic state index (TSI) can assess lake trophic status and trace in-situ metabolism, exhibiting a high potential in explaining autochthonous carbon dioxide (CO2) in aquatic environments. However, there remains a knowledge gap in how TSI links to the partial pressure of CO2 (pCO(2)) generated and consumed in lakes. Here we explored the temporal variations of lake pCO(2) and TSI, as well as their linkages in a karst plateau lake. Lake pCO(2) ranged from 90.1 to 7169.3 mu atm and was significantly high in the post-wet period (2534.3 +/- 1637.9 mu atm). Over 58% of samples were found to be supersaturated in CO2 with respect to the atmospheric equilibrium (410 mu atm). Biological and hydrological processes regulated lake trophic status, resulting in mesotrophic state (30 < TSI 50) in the post-wet period and eutrophic state (TSI 50) in the drought and initial-wet periods. Coupled carbonate dissolution and photosynthesis consumed the pCO(2), whereas groundwater and respiration contributed the pCO(2) in the karst lake. Our results highlighted that lake TSI could decipher trophic status and further partially explain the pCO(2) dynamics and sources. |
