| 摘 要： | 为研究富营养化湖泊水体温室气体浓度及其影响因素,以太湖西岸和竺山湾为例,共调查研究了27个点位,采用顶空平衡法对其表层水体中溶解的甲烷(CH_4)和氧化亚氮(N_2O)浓度进行测定.结果表明,太湖近岸带蓝藻水华堆积区表层水体中CH_4和N_2O两种温室气体浓度远远高于开阔湖区点位,CH_4和N_2O最高浓度分别为3.79±0.095和0.078±0.003μmol/L.蓝藻水华堆积区和开阔湖区CH_4平均浓度分别为2.33±1.46和0.14±0.059μmol/L,N_2O的平均浓度分别为0.054±0.024和0.023±0.012μmol/L.两种气体在水中均呈现过饱和状态,其中蓝藻水华堆积区表层水体中CH_4和N_2O饱和度远远高于开阔湖区点位.此外,入湖河流河口区域表层水体溶解性N_2O浓度较高.将水中CH_4和N_2O浓度与水体环境因子之间进行相关性分析,表明水体总氮、总磷、铵态氮和溶解性有机碳浓度与CH_4和N_2O浓度呈显著正相关,CH_4浓度与硝态氮浓度呈显著负相关.研究结果揭示了太湖蓝藻水华堆积区是CH_4和N_2O两种温室气体重要的潜在排放源,蓝藻水华暴发对湖泊温室气体的排放具有重要影响,但该过程的驱动机制及影响因素仍需要进一步研究.
