| description | Rivers are an important channel for the transfer of terrestrial carbon to the ocean and atmosphere.Therefore,the study of river carbon is of great significance for understanding the global carbon cycle.This paper reviews the research progress of carbon in river water,including:Spatial and temporal distribution,sources and influencing factors of river carbon content;River carbon source identification method;River carbon flux estimation method;Distribution and influencing factors of river p<sub>CO<sub>2</sub></sub>. Due to the different climatic conditions and flowing regions,carbon content,source and flux in rivers are obviously different.The identification methods of river carbon sources mainly include C/N ratio,carbon isotope,fluorescence spectrometry and biomarker,which have their own advantages and disadvantages.Therefore,the comprehensive application of multiple methods can improve the accuracy of source apportionment analysis results.River carbon flux is estimated by the product of river concentration and runoff,which is improved based on local river characteristics by later researcher.In the process of transport from land to sea,river carbon will also be released into the atmosphere in the form of CO<sub>2</sub>.Therefore,understanding the distribution of river p<sub>CO<sub>2</sub></sub> is of great significance for the study of biogeochemical cycle of river carbon. |
