Abstract

The invention provides a soil respiration measurement method, a soil respiration measurement device and a soil respiration measurement system. The method comprises the steps of measuring respiration data of soil in different layers according to preset time intervals; extracting the respiration data of the soil in different layers measured in a specified time slot; and acquiring carbon dioxide flux in soil respiration of different soil layers within the appointed time slot according to the respiration data. According to the method, the soil respiration of different soil layers can be automatically measured, and a basis can be provided for more accurately assessing influence of human activities on a carbon cycle of an ecological system by measuring the soil respiration of different soil layers.

Description

technical field [0001] The invention relates to the technical field of soil measurement, in particular to a soil respiration measurement method, device and system. Background technique [0002] Global warming and its impact is one of the most serious environmental problems facing mankind. The global carbon cycle largely determines the global climate change, and the CO caused by human activities 2 Emissions are an important cause of global warming. [0003] The carbon cycle is an extremely complex biological, chemical and physical process, which is affected by both natural and human activities. The earth's surface is a very heterogeneous system, especially the terrestrial biosphere is the most complex, because in addition to the rich and diverse vegetation types on the land surface, there is also a pedosphere with huge carbon storage. Therefore, so far, there are still considerable uncertainties in the issue of carbon sinks. [0004] As the largest terrestrial carbon pool ...
