- Abstract:
-
Soil respiration can be measured by two types of methods, i.e., micrometeorological method and chamber method. Chamber method has drawn much attention as the CO2 efflux from soil surface is measured directly by the technique. There are closed chamber and open chamber, both of which can be further divided into several kinds. In this paper, we mainly presented the principles, specialties, and application requirements for various chamber methods, and briefly commented on the development of soil respiration measurement in recent years. The static alkali absorption method, static closed-chamber method and dynamic closed-chamber method, which were widely used in the past, tend to be replaced by automatic open/closed chambers. It is expected that the newly developed automatic chambers, such as those manufactured by LI-COR, will be commonly used in the coming years. As soil respiration is one of the main pathways in the global carbon cycle and contributes to an important source for atmospheric CO2, the responses of soil respiration components to environmental factors in typical ecosystems will be extensively investigated. These researches will contribute not only to the calculation of ecosystem production, but also to the monitoring of CO2 emission dynamics under the condition of global changes.
