[0059] Further, if Figure 1 , 3 As shown, the top surface of the detection cover 1 is a spherical curved surface.

[0060] When the user uses the device to measure the carbon flux of the wetland ecosystem, first, the user buckles the detection cover 1 on the ground of the wetland area to be detected, so that the bottom port of the detection cover 1 abuts against the ground; then, the user sets the assembly ring 2 equipped with the positioning module on the detection cover 1, so that the tail ends of the multiple card plates 32 of the positioning module are respectively inserted into the inner cavity of the positioning card slot 311; thereafter, the user presses the assembly ring 2 downward to make the card plates 32 follow the guide of the positioning card slot 311 and move forward. The top of the inner cavity of the positioning card slot 311 slides to the bottom of the inner cavity of the positioning card slot until the inner cavity top wall of the assembly notch 322 opened on the card plate 32 abuts against the top of the limit stopper 312. After the inner cavity top wall of the assembly notch 322 abuts against the top of the limit stopper 312, the user continues to press the assembly ring 2 downward, and uses the card plate 32 to press the bottom port of the detection cover 1 located on the lower side of the plurality of assembly protrusions 31 into the wetland soil, thereby using the detection cover 1 to detect the wetland to be detected. The area is closed; when the user presses the assembly ring 2 downward, the bottom of the clamping plate 32 arranged on the assembly ring 2 is gradually inserted into the wetland soil, and the sub-plate 34 arranged at the bottom end of the adapter shaft 334 is also completely inserted into the wetland soil, thereby positioning the assembly ring 2 so that the assembly ring 2 will not be easily displaced when subjected to external force; when the inner cavity top wall of the assembly notch 322 abuts against the top of the limit stopper 312, the top of the sub-plate 34 is between the plane where the bottom of the assembly protrusion 31 is located and the plane where the bottom port of the detection cover 1 is located, and the tail end of the sub-plate 34 is driven by the elastic force of the second reset torsion spring to abut against the circumferential side wall of the detection cover 1; finally, the user connects the detection end of the analyzer with the detection cover 1, and the analyzer can be used to analyze the carbon dioxide generated inside the detection cover 1, and then calculate the carbon flux. In this embodiment, the analyzer belongs to the existing equipment, and the calculation method also belongs to the existing technology, so it will not be described in detail in this case.

[0061] When the user needs to put away the device, first, the user holds the assembly protrusions 31 arranged on the circumferential side walls of the detection cover 1 with both hands to drive the detection cover 1 to rotate radially. During the radial rotation of the detection cover 1, the tail ends of the multiple card plates 32 arranged on the assembly ring 2 are disengaged from the positioning slots 311, and are flipped back and forth under the manipulation of the multiple assembly protrusions 31, thereby expanding the gap width between the card plates 32 and the wetland soil to reduce the resistance of the card plates 32 from the wetland soil when the user pulls out the card plates 32; then, the user holds the assembly ring 2 with both hands to pull upward the multiple card plates 32 and the sub-plates 34 assembled on the assembly ring 2. During this process, the sub-plate 34 arranged at the bottom end of the adapter shaft 334 interferes with the assembly protrusions 31 and the limit block 312, thereby driving the detection cover 1 to move upward, thereby pulling the detection cover 1 out of the wetland soil.

[0062] Above, refer to Figures 1 to 6The wetland ecosystem carbon flux automatic monitoring device according to the embodiment of the present invention is described, which has the following beneficial effects:

[0063] 1. The device arranges an assembly ring and a plurality of positioning modules on the circumferential outer side of the detection cover, and by pressing the assembly ring downward, inserts the clamping plate and the sub-plate arranged on the assembly ring into the wetland soil, so as to achieve the purpose of positioning the assembly ring; and also achieves the purpose of positioning the detection cover by clamping the clamping plate arranged on the assembly ring with the positioning clamping groove arranged on the circumferential side wall of the detection cover, thereby solving the defect in the prior art that the supporting mechanism can only support one side of the detection cover, and has a poor positioning support effect.

[0064] 2. The device can support and position the detection cover by rotatably setting multiple clamping plates on the inner ring surface of the assembly ring and fixing multiple assembly protrusions on the circumferential outer wall of the detection cover. In addition, when the user drives the detection cover to rotate radially, the multiple assembly protrusions set on the circumferential side wall of the detection cover can be used to continuously move the clamping plate to flip back and forth, so as to expand the gap width between the clamping plate and the wetland soil, reduce the resistance of the clamping plate when the user pulls the clamping plate out of the wetland soil, thereby facilitating the user to pull the device out of the wetland soil and enhancing the convenience of use of the device.

[0065] 3. The device sets a sub-plate and a second reset torsion spring at the bottom end of the adapter shaft, and uses the elastic force of the second reset torsion spring to drive the tail end of the sub-plate to be close to the circumferential side wall of the detection cover, so that the user can hold the assembly ring and pull the card plate and the sub-plate inserted into the wetland soil upward, and use the interference between the sub-plate and the bottom of the assembly protrusion to pull the bottom port of the detection cover out of the wetland soil, thereby enhancing the convenience of use of the device.
