[0043] Referring to Figure 1 and Figure 2, generally speaking, the soil carbon dioxide flux in-situ measurement device of the present invention includes:
[0044] The bottom circle 3 is fixed in advance on the ground where the carbon dioxide flux of the soil surface layer is to be measured to determine the measured area;
[0045] When the soil carbon dioxide concentration is to be measured, the opening measuring container 6 installed on the bottom ring 3 is sealed;
[0046] The initial carbon dioxide concentration value (X1 ), sealing the lid 7 of the opening of the measuring container 6; and
[0047] The carbon dioxide analyzer 1 of the open measuring container 6 is connected.
[0048] Wherein, the carbon dioxide analyzer 1 uses infrared to measure the carbon dioxide concentration value of the soil.
[0049] Wherein, before the opening measuring container 6 is sealed and installed on the bottom ring 3, the air intake pipe 2 and the exhaust pipe 8 are used to connect the carbon di...
