十八世纪后期,科学家们发现氮这种元素对植物的生长具有促进的作用,并且有时起着决定性的作用,然而不是所有形式的氮都能够促进植物的生长,同时,也不是氮越多就越好。现代文明的高速飞速发展,使得氮的沉降量在逐年的增加,化石燃料的燃烧,用于农业生的氮肥等等,都对氮的沉降起到促进的作用,有的地区甚至都已经达到临界状态,氮的大量沉降对森林生态系统碳吸存的影响越来越明显,从而直接影响着森林中动物及植物的生存环境。从氮沉降对森林生态系统的影响出发,着重的对氮沉降对森林生态系统碳吸存的影响进行研究探讨。
In the late eighteenth century scientists found nitrogen as a contributing factor to plant growth and sometimes played a decisive role. However, not all forms of nitrogen promoted plant growth, nor were nitrogen more abundant The better. The rapid development of modern civilization, making the amount of nitrogen deposition increased year by year, the burning of fossil fuels, for agricultural nitrogen fertilizer, etc., all play a role in promoting nitrogen deposition, and some areas have even reached the critical State, the heavy sedimentation of nitrogen has a more and more obvious impact on the carbon sequestration of forest ecosystems, which directly affects the living environment of animals and plants in the forest. Based on the influence of nitrogen deposition on forest ecosystem, the impact of nitrogen deposition on carbon sequestration in forest ecosystem is discussed.
