摘    要:为探讨夏季池塘养殖河蟹系统温室气体的排放规律及综合增温潜势,试验采用静态暗箱-气相色谱法对池塘养殖河蟹生态系统温室气体(CO2 、CH4 、N2O)的排放进行原位测定。结果显示,夏季河蟹养殖池塘均表现为CO2 、CH4 和N2O的源,其中CH4夏季排放量达(42.62±9.55~95.09±10.89)g/m2,CO2排放量达(6.91±2.18~12.52±3.11)g/m2,N2O有微弱排放;夏季河蟹池塘保持一定的水生植物覆盖能显著减少CO2/ CH4的排放,较无水草种植区域,减少CO2排放 52.47g/m2,减少CH4排放 5.61 g/m2,对N2O排放无显著性影响;种植水生植物减缓综合温室效应的潜力是不种植水生植物的1.85倍,池塘养殖河蟹生态养殖温室气体减排空间巨大。

关 键 词:池塘生态系统  河蟹养殖  温室气体排放  综合增温潜势

Abstract: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
Keywords:pond culture ecosystem  culture of Chinese crab  greenhouse gas emissions  comprehensive global warming potentials
