摘    要:近几十年来,由于化石燃料和农牧业含氮化肥饲料的广泛使用,全球大气氮沉降量明显增加,一些地区已经达到饱和甚至超过了生态系统所能承受的临界负荷.过量氮沉降会对森林生态系统产生负效应.本文概述了全球氮沉降的现状,介绍了氮沉降增加对森林土壤和植物的影响机制,从而说明了我国开展氮沉降研究的必要性和紧迫性.

关 键 词:森林生态系统  大气氮沉降  影响

Abstract:In the last several decades,Human activities such as combustion of fossil fuels,intensive agriculture and stockbreeding,have significantly altered the global nitrogen deposition.The excessive N would produce negative effect on forest ecosystem.Based on published studies,actuality of nitrogen deposition at home and abroad is introduced,then the impact of increasing nitrogen deposition of the earth and plants in forest ecosystems is summarized,at last,the necessity and urgency of the study on nitrogen deposit...
Keywords:forest ecosystem  atmospheric nitrogen deposition  effects of excessive N
