Embodiment Construction

[0045] The present invention will be further described below in conjunction with specific embodiments.

[0046] like figure 2 A tree trunk shown in CO 2 As can be seen from the flux measuring device, it includes an infrared gas analyzer 5 and a gas channel connected to the infrared gas analyzer 5 and a lifting frame for placing the infrared gas analyzer 5 and its connected gas channel. The gas channel includes a trunk contact cover 2, Carbon Flux Gas Cell Contact Cover 4 (e.g. Figure 7 shown) and the steering pipe 3 for connecting the trunk contact cover 2 and the carbon flux air chamber contact cover 4. Specifically, the trunk contact cover 2 cover body is made of PVC material with an inner diameter of 10cm, and the contact end with the trunk can be processed according to the diameter of the tree to be measured, and the soft sealing gasket 9 at the arc-shaped notch 10 places can be soft polyurethane Foam for improved sealing against trunk surfaces of varying roughness. ...

Abstract

The invention relates to a trunk CO2 flux measurement device. The trunk CO2 flux measurement device comprises an infrared gas analyzer, a gas passage and a lifting frame used for arranging the infrared gas analyzer and the gas passage connected with the infrared gas analyzer, wherein the gas passage comprises a trunk contact cover, a carbon flux gas chamber contact cover and a steering tube used for connecting the trunk contact cover and the carbon flux gas chamber contact cover, the steering tube is arranged on the lifting frame through a fixing seat, the lifting frame comprises a desktop and desk legs located at the corners of the lower side of the desktop, each desk leg comprises a fixed segment and a telescopic segment located in the fixed segment, the fixed segment is connected with the telescopic segment through a locking device, a bearing platform is arranged between the desk legs, and a rail is arranged on the periphery of the bearing platform. According to the measurement device, the problem that a long-term test problem with high observation efficiency is difficult to carry out in a trunk breath process in the field for a long time is solved, the automation capability of plant trunk CO2 flux observation processes according to time scales such as day and night, seasonal variation and the like is greatly improved, manpower investment is lowered, and valuable data is provided for researches on trunk breath, carbon cycle of forest ecosystems, etc.

Description

technical field [0001] The invention relates to a measuring device for the flux of carbon dioxide, in particular to a measuring device and a measuring method for measuring the carbon dioxide emission of trunk respiration of tree species and large shrubs. Background technique [0002] Since the industrial revolution, with the rapid growth of economy and population, global atmospheric CO 2 The concentration keeps rising. A series of global climate change issues such as temperature rise, sea level rise, and extreme meteorological disasters caused by greenhouse gas emissions have seriously affected the health of natural ecosystems and human survival, production and life. [0003] Relevant studies have shown that about half of the carbon storage in the global terrestrial ecosystem is stored in the forest ecosystem, and the metabolic respiration of trees consumes the carbon that is photosynthetically fixed in the forest ecosystem and converts it into CO2. 2 form into the atmosph...
