摘要
综述了人类活动排放出来的Ｎ对大气的污染，使大气Ｎ沉降不断增加及过剩的Ｎ沉降对森林造成严重的影响；某些森林，由于Ｎ沉降的增加导致森林养分失调，增加了森林对寒冷、霜冻。
Deposition of atmospheric nitrogen has been increasing because of the atmospheric nitrogen pollution. The excessive nitrogen deposition has a significant effect on forest. For some forests, the increase in nitrogen deposition can result in forest nutritional disorder, and enhance the susceptibility of trees to the stress of cold, frost, fungal disease and possible insect attacks.
