Soil respiration measurement is the main way for carbon to return to the atmosphere from terrestrial ecosystem, and it is also the characterization of life activities in soil. Accurate measurement of its release is the key to evaluate the biological process in ecosystem; By monitoring soil respiration and its related parameters, the response of root box soil microorganisms to climate change can be estimated. Soil CO2 flux is affected by many complex physical and biological processes in time and space. Long-term, continuous and accurate measurement of soil carbon flux is of great significance to the study of terrestrial ecosystem carbon flux. The soil respiration meter can simultaneously display the CO2 concentration, soil temperature, photosynthetic effective radiation intensity, flow, air temperature and humidity of the respiration chamber.
