虾蟹混养池塘的温室气体排放及其影响因子
Greenhouse gases emission flux and impact factors in shrimp and crab mixed culture pond
摘要
Abstract
In order to reveal the greenhouse gases emission and influencing factors in shrimp and crab mixed culture pond,Eriocheir sinensis monoculture system(Q1)and mixed aquaculture system with high(Q2)or low(Q3)stock-ing densities of Macrobrachium rosenbergii were constructed.The greenhouse gases(CO2,CH4 and N2O)emission flux in these systems were determined by the static suspension box-gas chromatography(GC),and the water quality and meteorological indicators were also measured and used for correlation analysis.The results showed that the CO2 emission flux of Q1,Q2 and Q3 was-47.06-65.19,-36.57-118.10,-43.33-85.47 mg·m-2·h-1,respec-tively;the CH4 emission flux of Q1,Q2 and Q3 was 0.07-4.47,0.05-0.21,0.04-2.81 mg·m-2·h-1,respec-tively;and the N2O emission flux of Q1,Q2 and Q3 was-0.005-0.019,-0.031-0.009,-0.017-0.014 mg·m-2·h-1,respectively.The pH value of water was the main environmental factor affecting CO2 emission flux in ponds,while the concentration of nitrite nitrogen in the water was the main environmental factor affecting the CH4 and N2O emission.Global warming potential(GWP)of Q1,Q2 and Q3 was 348.61,209.29,226.81 g·m-2,respec-tively,and the unit product warming potential(UWP)of Q1,Q2 and Q3 was 2 294.24,970.97,1 296.80 g·kg-1,respectively.In general,co-culture of Eriocheir sinensis and Macrobrachium rosenbergii increased CO2 emis-sion flux,yet decreased CH4 emission flux,and had no significant impact on N2O emission flux.Compared with the monoculture of Eriocheir sinensis,the mixed aquaculture could improve the economic benefit and decrease the GWP and UWP.关键词
