Embodiment 1

[0036] This example provides a soil and atmospheric CO 2 and δ 13 C profile collaborative observation system, which includes sampling system, calibration system, control system and analysis system.

[0037] The sampling system is used to collect the gas in the atmosphere and the soil, and transmit the collected gas in the atmosphere and the soil to the analysis system through the control system; the sampling system includes a flux tower, a gas taking probe, an atmospheric gas pipe and Soil gas pipeline; the flux tower is fixed on the ground, and the flux tower is sequentially provided with a plurality of gas taking probes along the height direction, and the gas taking probes are used to collect the atmosphere; as an implementation form, this implementation In an example, the number of the gas taking probes is 6.

[0038] The air intake probe is connected to the atmospheric air pipe through a filter, so as to filter the dust in the atmosphere collected by the air intake probe...

Abstract

The invention discloses a cooperative observation system for a soil and atmosphere CO2 and delta 13C profile. The cooperative observation system for the soil and atmosphere CO2 and delta 13C profile comprises a sampling system, a calibrating system, a control system and an analyzing system; the sampling system collects gas in the atmosphere and soil; the control system controls switching of a gascircuit; the calibrating system carries out online calibration of the analyzing system; and the analyzing system detects CO2 and delta 13C in the atmosphere, and detects CO2 and delta 13C in the gas.According to the cooperative observation system for the soil and atmosphere CO2 and delta 13C profile, gas in the atmosphere and soil is collected through the sampling system, the collected gas in theatmosphere and soil is delivered to the control system; switching of the gas circuit is controlled through the control system; the analyzing system is subjected to online calibration through the calibrating system; and by the analyzing system, CO2 and delta 13C in the atmosphere are detected, CO2 and delta 13C in the gas in the soil are detected, and thus, the soil and atmosphere CO2 and delta 13C profile is cooperatively observed.

Description

technical field [0001] The invention relates to a carbon dioxide isotope comprehensive observation system for soil biogeochemical processes, in particular to soil and atmospheric CO 2 and δ 13 C Profile Collaborative Observation System. Background technique [0002] Soil and atmospheric CO 2 and δ 13 The detection of the C profile is of great significance for the carbon cycle, through the soil CO 2 and δ 13 The continuous determination of the gradient diffusion of C fluxes will significantly improve researchers' understanding of CO in soil profiles at different depths. 2 and δ 13 The cognitive ability of C characteristics and its migration mechanism; the development of online continuous observation technology has the unparalleled advantages of traditional isotope determination techniques and methods, which will greatly promote scientists' understanding of the dynamics and mechanism of soil organic matter decomposition. [0003] However, soil and atmospheric CO do not ...
