Abstract

The invention provides a collection device of greenhouse gases at different depths of a soil section. The collection device comprises a top gas collection barrel, at least one middle gas collection barrel, a bottom cover and connection devices, wherein the connection devices are arranged between the top gas collection barrel and the middle gas collection barrel, and between the middle gas collection barrel and the bottom cover, and are used for connecting the top gas collection barrel, the middle gas collection barrel and the bottom cover to form a detachable whole body. According to the collection device disclosed by the invention, the greenhouse gases at the different depths of soil can be accurately and continuously collected; and the collection device is simple in structure and easy to operate.

Description

technical field [0001] The invention relates to a gas collection device, in particular to a greenhouse gas collection device with different depths of soil profiles. Background technique [0002] Global climate change is a hot issue in current scientific research, and its impact on the earth's ecological environment is becoming increasingly prominent. At present, it is generally believed that climate warming is the result of changes in the global carbon cycle (C cycle). Soil is the largest terrestrial C pool on Earth and is the source of atmospheric CO 2 About 2 / 3 (1400-1500Gt) of C in the world is stored in the soil in organic form, which is 2-3 times the C pool of terrestrial vegetation and more than twice the global atmospheric C pool. CO released by soil respiration 2 Accounting for 25% of global C exchanges. [0003] Soil respiration is the exchange of CO between the soil and the atmosphere 2 The process is the result of soil carbon assimilation and dissimilation ba...
