摘要
从4个方面综述了木本植物对氮沉降增加的生理生态响应研究进展。(1)氮沉降增加引起木本植物组织氮浓度增加,从而改变其体内的氮代谢;(2)氮沉降影响植物的光合作用速率及与光合作用相关的含氮组分,一定范围内氮沉降会增加光合速率、光合色素和Rubisco含量;(3)氮沉降增加将导致植物的呼吸作用增强;(4)氮沉降增加不利于植物的抗逆性,导致植物的抗寒力和抗病虫害的能力下降。
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.
