Abstract

The invention relates to the salt marsh greenhouse gas emission research technology field and especially relates to an evaluation device and an evaluation method for a tidal influence on volatile halogenated hydrocarbon release in a salt marsh. The device comprises a cylinder, a seawater control device, a gas collection and detection device, an air exhausting device, a remote control end and a control system, wherein the cylinder is placed in a wetland soil column where vegetation is grown; the seawater control device is connected to the cylinder and is used for injecting seawater into the cylinder; the gas collection and detection device is connected to the cylinder and is used for collecting and detecting a gas generated in the cylinder; the air exhausting device is used for controllingcirculation and isolation of the gas in the cylinder and the outside world; the remote control end is used for carrying out remote control; and the control system is wirelessly or wiredly connected tothe remote control end. The control system comprises a controller. By using the device and the evaluation method of the invention, through simulating a tidal effect of seawater on salt marsh ecosystem waterflooding time and a waterflooding depth, a generated greenhouse gas emission flux can be conveniently, automatically and quickly detected. And then, a relationship between the tidal effect andsalt marsh greenhouse gas emission in an actual environment is acquired.

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 the release of volatile halogenated hydrocarbons in salt marshes affected by tides. 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 biochemical cycle of iodine; CH 3 Cl and CH 3 Br has high photochemical stability and low water solubility, about 17% of chlorine and 34% of bromine...
