| 摘 要： | 对浙西北丘陵地区夏季水稻田的大气甲烷进行浓度监测，结果表明，甲烷浓度的日变化十分明显，中午较低，早晚较高。甲烷浓度的梯度变化比较大。在不同时段及不同气象条件下甲烷的排放通量变化比较复杂。

| Abstract: | Methane concentration was measured on paddy field at hilly land of northwest Zhejiang province from July to September 1990. The results showed that the daily changes of methane concentration was obviously, low at noon and high in the morning and evening. The variation of methane concentration gradient was greater. The changes of discharge flux of methane concentration in different times and weathers is more complicated. |
