[0002] In the prior art, carbon flux is one of the most basic concepts in carbon cycle research, representing the total amount of carbon elements of an ecosystem passing through a certain ecological section. For example, the carbon flux of a certain river is the total amount of organic carbon and inorganic carbon flowing through the river section; the carbon flux of a certain forest ecosystem is the total amount of carbon cycle per unit time and per unit area of the ecosystem; the carbon flux of the ocean is the amount of carbon increase and decrease per unit time and per unit area. The measurement and calculation of carbon flux are of great significance for understanding the carbon cycle process and evaluating the carbon storage and emission of the ecosystem.
