Abstract

The invention relates to the technical field of research on the emission of volatile halogenated hydrocarbons in salt marshes, in particular to an evaluation device and an evaluation method for studying the emission factors of volatile halogenated hydrocarbon in salt marshes. The evaluation device includes a column body used for placing a salt marsh soil column with vegetation, a temperature control device used for controlling the temperature in the column body, a wind speed control device used for controlling the wind speed in the column body, a light control device used for controlling the light in the column body, an exhaust device arranged at the upper end of the column body and used for making the gas in the column body isolated from the outside, and a gas collection and detection device connected with the column body and used for collecting and detecting the gas generated in the column body. The evaluation device includes a control system which includes a controller. By controlling the temperature, light and wind speed of a salt marsh ecosystem, the evaluation device and the evaluation method of the invention can automatically and rapidly detect the emission flux of volatilehalogenated hydrocarbon generated and obtain the relationship between the temperature, light and wind speed and the emission of volatile halogenated hydrocarbon in the salt marsh, which is of great significance for the research of emission of volatile halogenated hydrocarbon.

Description

technical field

[0001] The invention relates to the technical field of research on greenhouse gas emission in salt marshes, in particular to an evaluation device and an evaluation method for researching release factors of volatile halogenated hydrocarbons in salt marshes. Background technique

[0002] Although methyl halide is the simplest compound among volatile halogenated hydrocarbons, it is the main substance that destroys the ozone layer. Methyl halides mainly include methyl chloride (CH 3 Cl), methyl bromide (CH 3 Br) and methyl iodide (CH 3 I), where CH 3 The photochemical stability of I is low, and it is difficult to reach the ozone-rich stratosphere, so the ozone depletion potential is small, but CH 3 I is the dominant iodine-containing compound in the marine environment and plays an important role in the global iodine biochemical cycle; CH 3 Cl and CH 3 Br has high photochemical stability and low water solubility, about 17% of chlorine and 34% of bromine in t...
