- Abstract:
-
Atmospheric nitrogen deposition has increased in the last several decades due to anthropogenic activities. Increasing nitrogen deposition has become an important factor regulating carbon cycle in global ecosystems. Fine root decomposition acts as an important carbon pool and a nutrient pool as well as the main sources of soil carbon and mineral nutrient in terrestrial ecosystems. Fine root decomposition also serves roles in interactions among plant, soil animal, microorganism and rhizospheric microecology. The effect of nitrogen deposition on fine root decomposition is complicated. Research on fine root decomposition mediated by nitrogen deposition has the important implications for elucidating the functions of rhizospheric microecology and predicting the response of ecosystems to global change. In this paper, the response of fine root decomposition to atmospheric nitrogen deposition is comprehensively summarized. The effects of nitrogen deposition on key factors affecting fine root decomposition are systematically analyzed. The underlying mechanisms of nitrogen deposition on fine root decomposition were discussed. The problems and shortcomings in the current research are analyzed, and the future research directions are prospected in order to provide the reference for further research on the feedback mechanism and interaction between nitrogen deposition and the carbon cycle of terrestrial ecosystems.
