Ec0physi0l0gical Responses of W oody Plants to Elevated Nitrogen Deposition
木本植物对高氮沉降的生理生态响应

During the past several decades, nitrogen deposition has brought a series of environmental and ecological problems. The subjects included in this literature review are: (1) elevated nitrogen deposition changes nitrogen metabolism in plants due to the increasing nitrogen concentration in plant tissues; (2) it influences photosynthesis including photosynthetic rate, photosynthetic pigments and Rubisco concentrations; (3) elevated nitrogen deposition increases plant respiration; and (4) increases the susceptibility of plant resistance to coldness, pests and diseases.
