为探讨团头鲂池塘养殖生态系统晒塘阶段温室气体的排放规律及综合增温潜势,采用静态暗箱——气相色谱法对团头鲂池塘养殖生态系统晒塘阶段温室气体(CO2,CH4,N2O)的排放进行原位测定。结果显示,团头鲂池塘养殖生态系统晒塘阶段均表现为CO2,CH4和N2O的排放源,其中CO2排放通量达(86.72±12.46)g/m2,CH4排放量达(2.01±0.34)g/m2,N2O排放量达(7.44±0.98)mg/m2;在100 a的时间尺度上,团头鲂池塘养殖生态系统在晒塘阶段综合增温潜势为(157.28±24.31)g/m2,团头鲂池塘养殖生态系统温室气体减排空间较大。
In order to investigate the law of greenhouse gas emission and the overall warming potential of the pond-growing ecosystem during the sunning pond period, static dark box-gas chromatography was used to determine the greenhouse gases (CO2, CH4, N2O) emissions were measured in situ. The results showed that all the ponds in the pond-growing ecosystem were all CO2, CH4 and N2O emission sources, of which CO2 emission reached 86.72 ± 12.46 g / m2 and CH4 emissions reached 2.01 ± 0.34 g / m2, and N2O emissions of (7.44 ± 0.98) mg / m2. On the time scale of 100 a, the overall warming potential of pond aquaculture ecosystem was 152.28 ± 24.31 g / m 2 at sunning pond stage, Tuantou pond aquaculture ecosystem greenhouse gas emission reduction a larger space.
