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。
Soil physical and chemical properties (such as soil temperature, soil water content, pH and soil C / N) are the main factors affecting N2O emission and emission from forest soils. At the same time, the types of forest and environmental disturbance (such as nitrogen deposition, land use / land cover Be changed, etc.) will also affect soil N2O production and emissions. The paper first discusses the mechanism of soil N2O production, and then summarizes the current domestic and foreign research results on the impact of the above-mentioned factors on soil N2O production and emissions, and finally puts forward the direction of future research.
