[0067] The above display module 4 can be an existing display device, such as a display screen or a monitor.

[0068] In summary, after the gateway system for forest scenic area carbon sink calculation of the present application obtains data through the data acquisition module 1, it outputs the data to the carbon sink calculation module 2 for calculation.
