Problems solved by technology

[0011] At present, research on greenhouse gas emissions from wetlands has been carried out in my country. Although some advanced instruments have been used to a certain extent in recent years, they are expensive and not conducive to widespread promotion. Therefore, many studies still use the static box method, but most of the static box methods T...

Abstract

The invention relates to a monitoring device for simulating wetland ecosystem greenhouse gas. The monitoring device comprises a box body and a box cover, wherein the interior of the box body is provided with a wetland soil matrix layer, a wetland plant layer and a wetland water body layer; an air extractor is connected to the box cover; and the wetland soil matrix layer, the wetland plant layer and the wetland water body layer are used for simulating the environment of a monitored wetland ecosystem. The monitoring device has the beneficial effects that the monitoring device is simple in structure, light in weight and convenient to move, and a plurality of parallel tests or a plurality of repeated tests can be set, so that the accuracy of an experimental result is improved; a sealing structure can be taken down at random, so that substance and energy flowing can be carried out on the simulated wetland ecosystem with the outside so as to maintain the wetland ecosystem to be continuously performed, and a sealing structure can be configured, so that a sealing system is formed by the whole set of device so as to make a preparation for accurate measurement; the whole device is smart in design and good in sealing performance, greenhouse gas emission of the corresponding wetland ecosystem can be accurately measured, the device is high in degree of accuracy and simple and convenient in operation, and unified standardized monitoring is conducted conveniently.

Description

technical field [0001] The invention relates to an ecological environment simulation monitoring device, in particular to a monitoring device for simulating a wetland ecosystem greenhouse gas and a method for using the same. Background technique [0002] Wetland is a unique ecosystem in the interlaced area of ​​water and land. Wetlands are areas of marsh, peatland and water, natural or artificial, permanent or temporary, with bodies of still or flowing fresh, brackish and salt water, including marine areas whose depth at low tide does not exceed 6 meters. Common natural wetlands include: swamps, peatlands, shallow lakes, river beaches, coastal tidal flats and salt marshes, etc. Artificial wetlands include rice fields, shrimp fields, crab fields, etc. There are many types of wetlands, large area and wide distribution. According to statistics, there are 8.558×10 wetlands in the world 8 ha, accounting for 6.4% of the total land area. [0003] The contribution of wetlands to ...
