| Abstract: | The carbon cycle is a focus area for research on global climate change, and carbon sinks and sources have become a hotspot in both global warming and earth science. Water bodies are an essential component of the biosphere and the carbon cycle, and receive a great deal of attention from national governments and the scientific community. However, traditional models of carbon cycling only considers oceans and neglects systematic inclusion of inland waters: the nutrient rich lakes, rivers and reservoirs characterized by high carbonate content. The mechanisms of inland water carbon storage are complex, and accurate carbon flux accounting is difficult. In this study, we reviewed the biological processes and mechanism of carbon storage by inland waters based on the theory of carbon cycling in oceans and dissected the scientific problems of carbon flux accounting. The factors influencing water carbon storage in inland waters was then addressed, including global climate change and water body eutrophication. Finally, we summarized the challenges faced by carbon storage by inland waters and methods for expanding carbon sinks, including aquatic ecological restoration, carbon storage by microbes and novel carbon storage mechanisms that couple submerged macrophytes and microbes in inland waters. |
