Progress of Microbial Residue Carbon in Terrestrial Ecosystems
Abstract:Microbial residues carbon, as an important component of soil organic matter, plays an important role in the carbon cycle of terrestrial ecosystems. It is an important part and dynamic repository of soil stable carbon pool. In this paper, the function of microbial residue carbon in terrestrial ecosystem, a brief history of the development of carbon determination method for microbial residues, the composition and characteristics of carbon in microbial residues, and the factors affecting the carbon quantity and composition of microbial residues are described in this paper. To clarify the significance of microbial residue carbon research, and point out the shortcomings of current microbial residue carbon research, and put forward the prospect.
