Description
Technical field
The utility model is related to a kind of Alpine Grasslands collection device of greenhouse.
Background technology
Terrestrial ecosystems are the important Yuan Hehui of greenhouse gases, the feedback under climate change situation to Atmospheric Chemistry into
Divide and play important adjustment effect.Grassland ecosystems are the important component parts of terrestrial ecosystems, global grassland area 3.4
×109hm2, the 26% of land surface is accounted for, there is significant impact to Global climate change.Meadow is the main vegetation class of China
One of type, area are 4 × 108hm2, the 11.8% of world's grassland area is accounted for, more than the 40% of Chinese area, in being is accounted for
The maximum terrestrial ecosystems of state, its area are about 4 times, 3.6 times of area of woods of Chinese arable land area.At present, meadow life
State system has become one of more serious terrestrial ecosystems of the effect of human activity, is more fragile land life in ecological environment
One of state system.China's Grassland ecosystems have huge carbon sequestration potentiality, its greenhouse gas emission that there is Global climate change
Material impact, to carbon sequestration capacity and the understanding being worth, it will help China gains the initiative in international carbon trade.Mankind's activity is done
Disturb down, the research that greenhouse gases are exchanged between terrestrial ecosystems and air is more and more concerned.
Observational study currently for dissimilar terrestrial ecosystems greenhouse gases becomes the focus of field of ecology.?
In all kinds of meadows in the whole nation, the Alpine Grasslands area that Qinghai-Tibet Platean has is maximum, and the gross area is 5883.42 ten thousand hm2, account for national meadow
The 17.77% of area, accounts for the 25% of China's land surface.Qinghai-Tibet height above sea level, plateau fiducial temperature are low, and Qinghai-Tibet Platean has
Special weather, vegetation and soil environment so that grassland soil development time is short, and Grassland ecosystems are especially fragile, High aititude
The regional ecosystem is the sensitizing range of climate change and Ecotone, and Qinghai-Tibet Alpine Grasslands are in China's Grassland ecosystems
In occupy critical role, which is played an important role in global warming gas balance between revenue and expenditure.Therefore, Qinghai-Tibet high and cold grass is studied
Ground vegetation-soil system greenhouse gas emission, is the important directions for understanding Alpine Grasslands aerodynamics and greenhouse effects phenomenon,
The flux of this area's greenhouse gases is determined and will provide important data basis for Qinghai-Tibet terrestrial ecosystems source, the estimation that converges,
It is of great significance for the greenhouse gases source of the Chinese Grassland ecosystem, the contribution tool that converges correctly is evaluated.
In order to be better understood by direction and the trend of climate change, it is necessary in the extremely sensitive response area of climate change, enter
Estimation of the row to the discharge capacity of Alpine Grasslands greenhouse gases, preferably reduces discharging and acclimatization change is arranged to formulate in time
Apply, with the impact of mitigation of climate change.For carbon nitrogen exchange capacity accurately between estimation Grassland ecosystems and air, correct evaluation
Status and effect of the Grassland ecosystems in Global Carbon nitrogen cycle and formulate scientific and reasonable taboo herd system provide science according to
According to.
Research soil is static chamber method with the main stream approach of atmosphere interface greenhouse gases flux Simultaneous Monitoring at present.Quiet
State case is typically made up of casing and base two parts, and before determining, floor installation in soil adopts when to be tested and there is certain body
Long-pending chest covers on the surface of tested soil or crop, is inserted simultaneously in the groove of base, with distillation water-stop, to ensure casing
Interior air is exchanged with ambient atmos airless, is extracted gas sample in case with syringe in a certain time interval, and is sent into laboratory
It is analyzed with gas chromatograph, so as to calculate the rate of release of greenhouse gases.In prior art, generally pacify at the top of casing
A fan is filled, to mix the gas in casing, as the volume of casing is larger, greenhouse gas emission has greatly space again
Inhomogeneities, the fan according to smaller power are then unable to reach the purpose that each point is well mixed in casing, affect the essence of observation
Exactness；If the quantity of the fan or increase fan using relatively high power, due to the disturbance of fan, nothing of the gas in box house
Sequence to flow and produce sinuous flow unordered in a jumble with the fluctuations of soil surface, changes the greenhouse gases under soil natural state
Discharge, while can also increase soil remittance absorbing state, the precision for affecting greenhouse gas emissions to determine.
