Abstract: The increasing trend of atmospheric nitrogen deposition changes soil physical and chemical properties, which affects the growth and development of plants directly, and affects the terrestrial ecosystem carbon pool indirectly, then it changes the global climate change process. Forest is the main component of terrestrial ecosystem, therefore, it has great significance to predict the global climate change by the study of how the nitrogen deposition affects carbon pool of forest ecosystem. The purpose of this article was to analyze the effect of nitrogen deposition on the input and output of forest ecosystem soil carbon pool, and elaborated the effect of nitrogen deposition on litter decomposition, fine root turnover and soil respiration in forest ecosystem. There were many researches on the effect of nitrogen deposition on the terrestrial ecosystem, and many tests were conducted by scholars both at home and abroad on how the forest ecosystem soil carbon pool responded to nitrogen deposition. However, most people focused on the aggregate analysis of carbon input and output instead of the components of carbon input and output separately. The authors summarized the related researches on the response of different components of input and output to nitrogen deposition, which provided reference for further study on response mechanisms and response ways.
