| 摘 要： | 基于2003-01～2005-06利用静态箱法对太湖水-气界面CO2交换通量的观测,对太湖水-气界面交换通量的变化特征进行了分析研究.结果表明:太湖水-气界面CO2交换通量存在明显的日变化,春、夏、秋、冬4季日平均通量分别为-0.79mg/(m2·h)、-4.89 mg/(m2·h)、-4.06 mg/(m2·h)和-2.56 mg/(m2·h),太湖均是CO2的汇.一般污染越重的区域,CO2通量值越大.藻型湖区水-气界面CO2交换通量季节变化不明显,草型湖区水-气界面CO2交换通量季节变化很明显,夏秋季高,冬春季低.CO2通量变化的可能相关因子还有天气情况、太阳辐射、风速及水温、pH、TA、Chla、TC、TN和TP等.

| Abstract: | Based on the measurement of the CO2 flux on the water-air interface of Taihu Lake by closed chamber technique from January 2003 to June 2005,variation characteristics of the CO2 flux on the water-air interface in Taihu Lake are analyzed.Diurnal variation of the CO2 flux on the water-air interface is obvious.The CO2 flux is-0.79(mg/(m2·h)) in spring,-4.89(mg/(m2·h)) in summer,-4.06(mg/(m2·h)) in autumn and-2.56(mg/(m2·h)) in winter.Taihu Lake is the sink of carbon monoxide.The CO2 flux gets larger in severer polluted area of the lake.Seasonal variation is not apparent in the algae type lake,but obvious in grass type lake.It is high in summer and autumn,and low in spring and winter.Correlative factors of CO2 flux on the water-air interface of Taihu Lake possibly include weather,solar radiation,wind velocity,temperature,pH,TA,Chla,TC,TN and TP. |
