摘要
影响森林土壤N2O产生和排放的主要因子为土壤理化性质(如土壤温度、土壤含水量、pH值以及土壤C/N等),同时,森林类型以及环境干扰(如氮沉降、土地利用/土地覆被变化等)也会影响土壤N2O产生和排放。文中首先论述了土壤N2O产生机制,然后综述了目前国内外关于上述影响因子对土壤N2O产生和排放影响的研究结果,最后提出未来应重点研究的方向。
The key factor influencing the N2O production and emission from forest soils is soil physical and chemical properties,such as soil temperature,water content,pH and soil C/N.In addition,forest type and environmental interference including nitrogen deposition,land use/cover change（LUCC） also can influence the N2O production and emission.In this paper,we firstly discussed the mechanism of soil N2O production process,and then reviewed the latest development in the studies concerning the influencing factors on forest soil N2O production and emission.Finally,we proposed that the future research direction.
