Fig. 12

Schematic depicting the main controlling factors of CO2 and CH4 emissions and their driving processes from reservoirs in the plateau region in this study. The primary driving processes include photodegradation, photosynthesis, aerobic and anaerobic respiration, methanogenic, terrigenous inputs and tributary inflows. The main controlling factors are Ta, Alti, Chl-a, DO, NH4+-N, pH, ORP, Precip, COD and TN.
