摘要：
Greenhouse-gas(CH(4), CO(2) and N(2)O) Measurements in nine Swiss hydroelectric reservoirs showed a supersaturation of methane and carbon dioxide leading to calculated emission fluxes of 0.1-0.5 mg (.) m(-2)-d(-1) of methane and 500-1700 mg (.) m(-2)-d(-1) carbon dioxide. Concentrations of N(2)O were close to saturation and fluxes negligible. Reservoirs from different altitude levels for greenhouse gas emissions showed no significant differences among each other.
