| 摘 要： | 通过总结得出温室气体静态采样箱设计的基本准则,并以洞庭湖不同湿地类型甲烷排放通量观测为出发点,设计了嵌套式采样箱。该采样箱的优势在于高度和体积可调节,运输和不使用时,顶箱可放入延长箱中不占体积;使用时,顶箱扣在延长箱上增大体积,采样箱高度随延长箱数量的变化而改变。稻田试验性观测发现,洞庭湖区4月早稻甲烷的平均排放通量为10.37mg/(m2·h)。结果表明,应用嵌套式静态采样箱开展湿地甲烷监测结果可靠。但采样操作需在40min内完成,以避免箱体内部环境变化引起甲烷排放不稳定。

| Abstract: | Basic rules for making greenhouse gas sampling equipment were summarized,and a nested sampling chamber was designed to measure methane emission fluxes of different kinds of wetland around Dongting Lake.The advantage of the chamber was its adjustability of height and volume.When transported or not in use,reduced volume could be realized by setting the top of the chamber into the middle of it;when used,expanded volume could be generated by setting the top of the chamber upon the middle of it.The height of the... |
