| 摘 要： | 小型池塘作为内陆水体的一部分,是被忽视的温室气体重要排放源.本研究主要利用通量-梯度方法测量长江三角洲地区的一处小型池塘水-气界面温室气体(CO_2和CH_4)交换通量.结果表明:1零梯度测试结果显示本套通量-梯度系统测量H_2O、CO_2和CH_4通量的精度分别为7.525 W·m-2、0.022 mg·(m2·s)-1、0.054μg·(m2·s)-1,并且在正常实验观测期间3种气体(H_2O、CO_2和CH_4)的通量值分别有84%、80%和94%的结果高于零梯度测试精度,以上结果可以保证本套通量-梯度系统具有足够的精度测量池塘水-气界面温室气体交换通量;2通量-梯度计算结果表明此小型池塘在夏季为CO_2和CH_4的排放源,其排放通量平均值分别为0.038 mg·(m2·s)-1和0.889μg·(m2·s)-1,其中CH_4排放通量远高于内陆湖泊甲烷排放通量的中值,说明小型池塘的温室气体排放量是估算内陆水体温室气体排放量特别是CH_4排放量中不可忽视的重要量值,本研究结果可为准确估算区域温室气体排放量提供科学参考.
