Solute production and transport processes in Chinese monsoonal rivers: Implications for global climate change

Concentration-discharge (C-Q) relationships provide new insights into solute production processes. Temporal sampling and analyses are needed to investigate the chemical weathering behaviors and reduce the estimation errors of fluxes. However, few studies have been done on Asian monsoonal rivers, which play an important role in global carbon cycle. We analyzed the dissolved solutes of the Three largest rivers in China. Datong and Qingxi in Changjiang River were selected to represent the midterm and outlet of the Changjiang River. Lijin was selected as the outlet of the Yellow River. We analyzed the major ions, which can represent the chemical weathering index. Our study may help deepen the understanding of chemical weathering and solute fluxes., We sampled monthly in large Chinese rivers, the methods are available in 2020GB006541.
Note: Datong is the outlet of Changjiang River, Lijin is the outlet of Yellow River, Qingxi is the inlet of Three Gorges Dam., ,
