Description

Technical Field

[0001] The present application relates to the technical field of greenhouse gas measurement devices, and in particular to an amphibious greenhouse gas measurement device. Background Art

[0002] Since the Industrial Revolution, greenhouse gas emissions caused by human activities have been the main cause of global warming. Greenhouse gases refer to gases in the atmosphere that can absorb long-wave radiation reflected by the ground and re-emit radiation. Water vapor, carbon dioxide, nitrous oxide, freon, methane, etc. are the main greenhouse gases in the earth's atmosphere.

[0003] Current scientific research shows that in addition to carbon emissions from industrial development such as chemical, energy, and transportation, freshwater aquatic ecosystems are also an important "source" of greenhouse gases in the atmosphere. Inland water bodies bury carbon in sediments through sedimentation, while also emitting greenhouse gases such as CH4 and CO2 into the atmosphere. They play an important role in the global carbon cycle, and their carbon emissions are receiving increasing attention.

[0004] At present, the more mature method for collecting greenhouse gases in water bodies is the "static box + gas analyzer" method; for environmental scenarios in the water-gas state, a floating static box is usually used to collect the diffused gas at the water-gas interface, and then a gas analyzer is used to measure the gas composition and content in the static box;

[0005] For environmental scenarios at the solid-gas interface, such as measuring drawdown zones (especially large and medium-sized reservoirs) or buffer zones (shoreline areas of artificial or natural lakes), a static box is usually placed on the ground, the measurement site is snapped into the static box, and then the analyzer is used to measure the gas in the static box;

[0006] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: when measuring the water-air interface, the static box may shake; when measuring the drawdown zone or buffer zone, the static box is placed on the ground at an angle, and there is a possibility of tipping over, resulting in the possibility of exchange of gas in the static box with external gas, resulting in large errors in the measurement data.
