The invention discloses a chamber method matter flux automatic observation system. The chamber method matter flux automatic observation system comprises a main pipeline, N measuring channels, a main control unit, an analytical unit, and an information unit. Each measuring channel comprises an observation chamber which is placed in an area to be detected. Each of the N (N>=1) measuring channels is connected with the measuring main pipeline via a pipeline; the main control unit comprises N first two-site two-way magnetic valves which are arranged in the N measuring channels respectively; the analytical unit is connected with the main control unit, and is used for measuring gas sample component content; the information unit is used for controlling the main control unit to perform following operation: an observation chamber of a selected measuring channel is controlled to be closed, the first two-site two-way magnetic valve of the selected measuring channel is controlled to be open, gas sample in the selected measuring channel is controlled to be delivered to the analytical unit; and the analytical unit is used for measuring the content of gaseous components.
Description
technical field [0001] The invention relates to the field of monitoring of terrestrial ecosystems, in particular to a system and method for automatic monitoring of gaseous substances exchanged between terrestrial ecosystems and the atmosphere with a box method and a method for high-frequency continuous monitoring. Background technique [0002] Climate change and human activities severely affect terrestrial ecosystems (forests, grasslands, deserts, wetlands, and farmlands). As the main body of human living environment, terrestrial ecosystems have a feedback effect on this dual impact. The process of material exchange between terrestrial ecosystems and the atmosphere is positive. It is the way of this superimposed influence and feedback effect. In-depth study of the exchange of gaseous substances (greenhouse gases, gaseous active carbon and nitrogen components, water vapor, gaseous pollutants, etc.) between the terrestrial ecosystem and the atmosphere is the key to correctly un...
