Abstract

The invention discloses an open soil carbon flux monitoring instrument and monitoring method. The monitoring instrument comprises a cylinder, wherein the top and the bottom of the cylinder are both opened, two data acquisition modules are arranged on the inner wall of the cylinder and are respectively located at the top and the bottom of the inner wall of the cylinder, each data acquisition module comprises a carbon dioxide sensor, a temperature sensor and an atmosphere pressure sensor, the cylinder is also provided with a central processing unit and a display screen, and the central processing unit is electrically connected with the display screen and with the carbon dioxide sensor, the temperature sensor and the atmosphere pressure sensor of each data acquisition module. The open soil carbon flux monitoring instrument and monitoring method provided by the invention adopt an open monitoring manner, so detection accuracy is improved, and normal monitoring can be carried out in rainy days.

Description

technical field [0001] The invention relates to the technical field of soil carbon flux monitoring, in particular to an open soil carbon flux monitor and a monitoring method. Background technique [0002] CO2 is the main greenhouse gas in the atmosphere, and its massive emission has led to the deterioration of the global climate. The frequent occurrence of extreme weather events in recent years is nature's most severe punishment for human activities. The basis of carbon trading is carbon sink measurement, and the establishment of a unified carbon sink measurement system is the guarantee for orderly, healthy and fair carbon trading. The most complicated and difficult part of carbon sink measurement is the measurement of the underground part, that is, the measurement of soil carbon flux. Soil carbon flux refers to the amount of CO2 passing through the soil per unit area per unit time. Soil is a huge carbon pool, with a total storage capacity of 1394Pg C (1Pg = 1015g), which ...
