Abstract
Soil respiration has an important impact on global climate change and the carbon cycle. Therefore, it is necessary to accurately analyze the principles of soil respiration monitoring. Various monitoring principles tend to deliver partially different results. In order to reduce the difference, it is necessary to explore the ways to improve the principles. The present studies focus mainly on different methods of soil respiration monitoring, but rarely on their relative principles. This paper makes comparison between the dynamic airtight chamber method, the dynamic open chamber method, the gas well method and the model method based on the domestic and foreign literature, and further discusses the calibration improvement methods according to the relevant principles, aiming to reduce the result difference between different monitoring principles.
