Description
Technical field
The utility model relates to a kind of eudiometry device, specifically, is a kind of aqueous vapor interface carbon dioxide flux determinator.
Background technology
Carbon dioxide (CO in the atmosphere
2), methane (CH
4), nitrous oxide (N
2O) rising of isothermal chamber gaseous mass concentration and the warming effect that causes thus are one of the severeest global environment problems of face of mankind.CO
2Greenhouse effect account for 50% of total greenhouse effect weight, its mass concentration before the industrial revolution 280 * 10
-6Be increased to present 365 * 10
-6It is one of important composition of global change research due that the carbon cycle of terrestrial ecosystems and carbon are accumulated, and lake ecosystem is as the part of terrestrial ecosystems, and the exchange of the carbon at its water-aerosphere face, water-land interface, water sediment interface is very important.Since mid-term in last century, lake water-aerosphere face carbon exchange research has caused numerous scholars' concern.According to researchs such as Downing, the lake is to Atmospheric CO
2Aggregation (in C) reach 5.32 * 10
7T/a.Therefore, lake water-aerosphere face carbon flux research is significant to the exploration of global carbon rule.Lot of domestic and foreign scholar is to the big quantity research of carbon exchange having carried out of lake water-aerosphere face; But overwhelming majority work all concentrates on the model study and the total amount estimation of lake water-aerosphere face carbon exchange; Lack quantitatively accurate observational study, its reason mainly is to lack suitable determinator.The conventional method of measuring aqueous vapor interface carbon dioxide flux at present is: use static sampling box to gather gas, transport the laboratory back through collection gases such as wireways then and analyze.This kind method has various disadvantages: on-site measurement can not be carried out in (1), and the transportation of gaseous sample can cause the loss of gas, causes the mensuration result inaccurate; (2) gas of transporting back needs the regulation according to HJ/T167-2004 " indoor air quality monitoring technical manual ", and 12 hours inner analysis after gas is collected well finish, and is to be difficult to accomplish like this under the bigger situation of sample size; (3) sampling box does not have unified specification, the comparability between inconvenient each data.Therefore, need badly a kind of can field monitoring CO
2Flux, observed result are accurately, specification fixes, is beneficial to the determinator that compares between the data, but also do not appear in the newspapers about this type device at present.
