Monitoring device for researching relation between illumination and soil carbon flux

Abstract

The invention relates to a monitoring device for researching a relation between illumination and a soil carbon flux. The monitoring device comprises a base; a monitoring hole is formed in the middle part of the base; a lighttight cover body and a light-transmitting cover body are respectively hinged to positions, located on two sides of the monitoring hole, on the base; the lighttight cover body is driven by a first driving mechanism to do turning motion, so as to close or open the monitoring hole; the light-transmitting cover body is driven by a second driving mechanism to do turning motion,so as to close or open the monitoring hole; and interfaces for mounting monitoring sensors are respectively formed in the lighttight cover body and the light-transmitting cover body. The monitoring device disclosed by the invention can be used for monitoring soil respiration related parameters under a natural environment and can be also used for monitoring soil respiration related parameters undera dark environment; two groups of comparative data are acquired, so as to further research the relation between the illumination and the soil respiration favorably; and the monitoring device has an important significance for pushing the research on the carbon flux of a terrestrial ecosystem.

Description

technical field [0001] The invention relates to the technical field of soil carbon flux measurement, in particular to a monitoring device for studying the relationship between light and soil carbon flux. Background technique [0002] Soil respiration is the main way for carbon to return to the atmosphere from terrestrial ecosystems, and it is also a characterization of life activities in soil. Accurate determination of its release is the key to evaluating biological processes in ecosystems. By monitoring soil respiration and its related parameters, the responses of roots and soil microbes to climate change can be estimated. Soil CO 2 Fluxes are affected by a variety of complex physical and biological processes in time and space. Long-term, continuous, and accurate measurement of soil carbon fluxes is of great significance to the study of carbon fluxes in terrestrial ecosystems. [0003] At present, relevant researchers in this field have achieved some results in the monito...

Problems solved by technology

However, these devices all use a transparent monitoring space as the research object, so these devices can only be used to study the relevant parameters of soil respiration in a natural environment, and cannot be used to further study the impact of parameter changes on soil respiration
