Problems solved by technology

First of all, the mangrove woody plants are large in size. If the traditional static box design is used, the box will be bulky, the overall device cost is high, and it is difficult to move; secondly, the sampling plant shearing method is not suitable for mangrove plants. Firstly, it causes damage to the plant itself, and secondly, it ignores

Embodiment Construction

[0020] The present invention is used to measure the static box of mangrove trunk methane transmission rate, such as figure 1 , 2 Shown, comprise box body 1, box body 1 upper side middle part and lower side middle part are respectively provided with a section and the sleeve pipe 2 that diameter of trunk adapts to enclose trunk, and box body 1 is formed by the front half box body 19 that can be relatively laterally opened. Composed with the rear half box body 20, the sleeve pipe 2 is also correspondingly divided into a front half sleeve pipe arranged on the front half box body and a rear half sleeve pipe arranged on the rear half box body. In this embodiment, one side of the front half box body 19 and the rear half box body 20 is connected by a hinge 17, and the other side can be opened and closed relatively freely, so as to facilitate the installation or disassembly of the static box body.

[0021] A sampling port 3 and an air pressure balance pipe 4 are also provided on the b...

Abstract

The invention relates to a static box for measuring the methane transmission rate of mangrove forest trunks. The static box comprises a box body, the middle portion of the upper side surface of the box and het middle portion of the lower side surface of the box are respectively provided with a segment of a sleeve adapting to the diameter of a trunk in order to encasing the trunk, the box body is composed of a front half box body and a rear half box body which are oppositely laterally open to each other, the sleeves are correspondingly divided into front half sleeves arranged on the front half box body and rear half sleeves arranged on the rear half box body, and the box body is also provided with a sampling opening and a gas pressure balancing tube. The static box has the advantages of realization of accurate measurement of the methane transmission rate of the mangrove forest wetland woody plant trunks, simple structure, easiness in manufacturing, good portability and easiness in operation.

Description

technical field [0001] The invention relates to a static box for measuring the methane transmission rate of mangrove trunks, which is suitable for the investigation field of greenhouse gas emission in atmospheric science, environmental science, physical geography and ecology. Background technique [0002] Global warming is one of the environmental issues of common concern to all mankind. As an important greenhouse gas, wetland methane (CH 4 ) emissions related research has become a common concern in the academic circles. Methane transport pathways in wetlands include diffusion transport, air bubble transport and plant body transport, etc. Among them, plant body transmission has the characteristics of high efficiency and fast speed. At present, many domestic studies have quantitatively measured the methane transport rate of wetland herbaceous plants, but there are few studies on the methane transport rate of woody plants. It is estimated that about 80 Tg / year of methane i...
