摘要
通过氮沉降对温室气体二氧化碳(CO_2)、甲烷(CH_4)和氧化亚氮(N_2O)排放产生的影响进行简要概述,并从碳氮转化途径的角度解释了CO_2、CH_4和N_2O通量对氮沉降的响应机制,由于氮沉降使土壤中C、N的转化过程发生了改变并相互影响,探讨相互耦合的C、N动态对氮沉降的响应,有利于加深温室气体对氮沉降响应的研究。
This article gives a brief overview of effects of nitrogen deposition on the greenhouse gas such as carbon dioxide(CO2),methane(CH4)and nitrous oxide(N2O),and explains the response mechanism of CO2,CH4and N2O fluxes on the nitrogen deposition from the transformation ways of carbon and nitrogen.Nitrogen deposition change the transformation process of C and N in soil that they influenced each other,discussing the response to nitrogen deposition on mutual coupling of C and N dynamic is conducive to deepen the research of greenhouse gas response to nitrogen deposition.
