[Advances in studies on transported flux and properties of riverine organic carbon].

Some lately advances in the study of riverine organic carbon were summarized in this paper. The transported flux of organic carbon from terrestrial ecosystems to the oceans via rivers, which is one of the most sensitive land surface processes in global climate change, has been changed in quantity due to the anthropogenic disturbance to it. The properties of riverine organic carbon, even in the same drainage, changed notably with the changes of hydrological processes in the drainage. Riverine organic carbon may become aged since they have been metabolized by the riverine microbes in the processes of being transported to the seas from the land, i.e., the radiocarbon in the riverine organic carbon was partially degraded by the microbes.
