Greenhouse Gases Emissions from Pond Culture Ecosystem of Chinese Crab and Their Comprehensive Global Warming Potentials In Summer

In order to analyze the seasonal variation characteristics of emissions of CO2 ,CH4 , N2O and evaluate the comprehensive global warming potentials (GWPs),Fluxes of CO2,CH4 and N2O were measured simultaneously from the culture ponds of Chinese mitten crabs by the closed static opaque chamber-GC techniques. The results showed that the pond ecosystem were the sources of CO2
