Abstract: In order to explore the impact of plant growth under the background of increasing global nitrogen (N) deposition, the author summarized the literature data of different growth indices of forest plant to N deposition in this paper. On the basis of previous research results, the author detailedly summarized the effects of N deposition on the plant morphology above the ground (plant height, the stem base diameter), Photosynthetic physiology (content of photosynthetic pigments, net photosynthetic rate), soluble sugar content, biomass allocation proportion between aboveground and underground, root morphology structure (length, diameter and biomass of root system) and stoichiometric ratio between N and P in the leaf, then we made a reasonable analysis about the above changes. It is pointed out that the increase of N deposition obviously promote every plant growth index to some extent, however, the growth of plants will be restrained when the N deposition was pretty serious. The author found that many current N deposition simulation experiments were short-term and most of them paid more attention to the study of phenomena rather than the mechanism. It is suggested that the duration of simulation experiments should be further extended and the mechanism of changes should be explored in order to provide a great reference for further study on the effect of N deposition on the growth of forest plant.
