Description
Technical field
The present invention relates to a kind of soil-plant system gas exchange continuous measurement acquisition device.
Background technology
Soil-plant system is the important source of minimum gas in the atmosphere (as CO2, CH4, N2O), because the variation of minimum gas concentration has caused a series of great global environmental changes, as the reinforcement of greenhouse effect in the atmosphere, the attenuating of ozone concentration, the warming of global climate.Soil respiration (soil respiration) is meant the process of soil release of carbon dioxide, i.e. the aerating tissue that the gas that produces in the soil can be by plant or dredge tissue and be transferred in the atmosphere, simultaneously atmosphere also equally approach deliver gas to soil.Say on the stricti jurise to be meant all metabolism that produce carbon dioxide in the undisturbed soil, comprise three biological processes (being soil microorganism breathing, root system respiration, soil animal breathing) and an abiology process.Be the several biology and the abiology processes such as chemical oxidation effect of carbon containing mineral matter.
Forest soil respiration is the pith of terrestrial ecosystems soil respiration, and its dynamic change will produce far-reaching influence to global Carbon balance.Whole world forest over-exploitation and other soil utilizations change the recruitment that causes soil CO2 to discharge, and half of the CO2 total amount that twoth century of accounting for over discharges because of mankind's activity is to remove another key factor that fossil-fueled release CO2 causes the rising of atmosphere CO 2 concentration.Therefore, set up CO2 flux website, forest, prairie soil are breathed carried out long term monitoring, research soil-plant system gas exchange, be the important topic of research world's carbon cycle, ecology, environmental science and earth surface system the reach of science are of great importance.
Summary of the invention
In view of above-mentioned, the object of the present invention is to provide a kind of soil-plant system gas exchange continuous measurement acquisition device.
Technical scheme of the present invention is:
A kind of soil-plant system gas exchange continuous measurement acquisition device is made up of seal closure tube of the no end, band groove sealing base, microclimate data collecting instrument, temperature sensor, gas agitation fan, outlet nozzle, air-breathing little air pump, valve, airbag, silica gel catheter, wind speed wind direction sensor, accumulator and solar electric power supply system.Seal closure tube of the no end is buckled and is put into band groove sealing base, gas agitation fan and temperature sensor are equipped with in seal closure tube top, the no end, the microclimate data collecting instrument is connected with gas agitation fan, temperature sensor and wind speed wind direction sensor, accumulator and solar electric power supply system respectively by lead, and air-breathing little air pump, valve, airbag are communicated with the cover outlet nozzle by silica gel catheter.
Above-mentioned solar electric power supply system is solar charger and solar cell.
Advantage of the present invention is:
1, the light transmission of cylindrical shell also has direct influence for the exchange flux of ground plant CO2.The present invention does not have end seal closure tube and adopts circle or the light tight PVC material of square white to make, the white light-proof material can increase the radiation of barrel to sunshine, reduce the speed that temperature raises in the tube, slow down an interior variation of temperature, guarantee the accuracy of soil-plant system gas exchange emission flux of gas data acquisition.
2, the seal closure tube buckles in the groove of stainless steel pedestal the no end, and uses water-stop.The microclimate data collecting instrument can be provided with 1-3 collection of connection and repeat a little, long term monitoring is carried out in forest, grassland and the soil respiration of Desert of Gobi group, accumulation data, analysis and evaluation is for ecology, environmental science and earth surface system the reach of science provide reliable foundation.
3, simple in structure, easy to operate, portable, be the desirable utensil that the soil-plant system gas exchange continuous measurement scientific experimentation is carried out in the field.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, utilize soil-plant system gas exchange continuous measurement acquisition device to forest, grassland and the soil greenhouse gases (CO2 of Desert of Gobi group, CH4, N2O) flux and indoor and outdoor temperature microclimate change and carry out METHOD FOR CONTINUOUS DETERMINATION, Acquisition Instrument is by seal closure tube of the no end 1, band groove pedestal 2, microclimate data collecting instrument 3, temperature sensor 4, gas agitation fan 5, air-breathing stingy pump 6, valve 7, airbag 8, silica gel catheter 12, wind speed wind direction sensor 9, accumulator 13 and solar electric power supply system 10 are formed, the light tight PVC material of seal closure tube 1 usefulness 5mm of no end white is made, cylindrical shell is circular and square two kinds, the internal diameter floorage is diameter 450mm and 480 * 440mm, and box height is 30mm.Seal closure tube of the no end 1 is buckled the groove of putting into the stainless steel pedestal that inserts soil 5-15mm depths, and use water-stop. seal closure tube 1 top, the no end is equipped with gas and is stirred small fan 5 and 3 differing heights temperature sensors 4, the bottom is buried 3 different depth soil moisture sensors 4 underground, microclimate data collecting instrument 3 contains the single-chip data storage card, 232 interfaces, 232 interfaces by lead respectively with gas agitation fan 5, temperature sensor 4, wind speed wind direction sensor 9, accumulator 13 is connected with solar electric power supply system 10, air-breathing stingy pump 6, valve 7 and airbag 8 are communicated with cover outlet nozzle 11 by silica gel catheter 12.
3 collections are set respectively in 3 sample ground repeat a little, soil maintains the original state as far as possible in the sampling box pedestal, and cylindrical shell and pedestal are shrouding plant.Soil and plant are all having gas exchange process with atmosphere in varying degrees, begin to mid-October from late May, carry out the emission flux of gas sample collecting with average 2 times/month sample frequency, each sample gas 200ml injects in the sampling airbag, transports back in the laboratory and in time analyzes.The sampling time basic fixed is at 8:30 to 10:00 in the morning, with the average daily flux of the flux representative sampling of this moment day, the cover tube at the beginning, microclimate data outside synchronous acquisition the temperature inside the box, the soil moisture and the case regularly respectively when 15min and 30min.
Solar cell was given 3 power supplies of microclimate data collecting instrument, was charged to solar charger daytime; At night, solar charger gives the microclimate data collecting instrument 3 power supplies.Overcast and rainyly give the microclimate data collecting instrument 3 power supplies by accumulator 13.
