文摘
- •
Multiple-scale concentrations, stoichiometric ratios and fluxes of nutrients are studied.
- •
High-flow months show unprecedented contribution to annual nutrient loads.
- •
Anthropogenic activities significantly increase concentrations and fluxes of nutrients.
- •
Human activities alter nutrient limitation from N to P for phytoplankton growth.
- •
Nutrient fluxes are (×109 mol/y): DIC (414.5), DSi (62.8), DIN (4.1) and DIP (0.3).
