Continuous increasing production and deposition of nitrogen will have a significant impact on carbon cycling of ecosystems. Soil respiration is the important component of carbon cycling in terrestrial ecosystems, the only way to release carbon into atmosphere from soil carbon, and an important source of atmospheric CO 2. Study on the response of soil respiration to nitrogen deposition is significant for understanding the role of soil respiration in the mitigation of climate change. By using the experimental method of positioning the simulated nitrogen deposition, this research was focused mainly on the variations in soil respiration, and the short鄄term response of each component of soil respiration to different levels of
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
