Abstract
A device and method for field in-situ multi-plot synchronous monitoring of greenhouse gas fluxes, wherein a transparent plexiglass chamber is fixed to a stainless steel base, and the plexiglass chamber is provided with two movable square plexiglass plates; the square plexiglass plates are connected to the plexiglass chamber through push rods, and the push rods are configured to close or open the square plexiglass plates, so to seal or communicate the plexiglass chamber; sampling tubes are arranged on side walls of the plexiglass chamber; one ends of sampling pumps are connected to the sampling tubes; one end of each sucking pump is connected to each sampling tube through a solenoid valve, and the other end of each sucking pump is connected to a gas analyzer through a switch; and the gas analyzer is connected to a computer host, configured to measure concentration data of gas in the sampling tubes.
