CO2 flux measurement device and method used in intertidal wetland

Abstract

The invention relates to a CO2 flux measurement device used in intertidal wetland. The device comprises an infrared gas analyzer, a gas path and an erector, wherein the gas path is connected with the infrared gas analyzer, the erector is used for placing the infrared gas analyzer and the gas path, the gas path comprises a transparent water-touching cover and a wave protection pipe; a plurality of sharp angles are uniformly distributed on the lower edge of the water-touching cover; scales are arranged on the side wall of the water-touching cover; a level gauge is arranged on the water-touching cover; the other end of the wave protection pipe is connected with a carbon flux air chamber contact cover; the wave protection pipe is connected with a lifting rod at one side angle of the erector through a fixing ring; the erector comprises a table top and table legs; the table legs comprise fixed sections and stretching sections positioned inside the fixed sections; sharp ends are arranged at the front ends of the stretching sections; the fixed sections are connected with the stretching sections by virtue of a locking device. Based on mutual cooperation of the gas path and the erector as well as the infrared gas analyzer in the measuring device, the problem that the traditional CO2 flux measurement method for inland wetland is difficultly used for effectively measuring the intertidal wetland for a long time is solved, the high automation capability is realized, the operation is time-saving and labor-saving, and the aim of continuously measuring for a long time is achieved.

Description

technical field [0001] The invention relates to the field of carbon dioxide flux research, in particular to a method for intertidal wetland CO 2 Flux measuring device and its measuring method. Background technique [0002] Today, a series of ecological and environmental problems caused by rising global temperatures, such as rising sea levels, melting glaciers, and increasing extreme meteorological disasters, have seriously affected the health of natural ecosystems and human survival and production. with CO 2 As the main factor affecting the rise of global temperature, the emission of greenhouse gases, which is the main factor, has attracted more and more attention. Scholars from various countries are constantly calling for a new energy revolution and promoting the progress of carbon emission reduction actions. At the same time, they are also actively investing in the research on the carbon cycle of natural ecosystems, aiming to understand the carbon metabolism process of d...
