氮沉降对森林生态系统的影响研究

Research on the Influence of Nitrogen Deposition on Forest Ecosystem

土壤一植物一大气连续体(SPAC)的大气和土壤氮沉降量的不断增加,改变着区域和全球环境,导致现有森林生态系统的生物与环境间的物质循环、能量转换和信息传递受到严重影响。本文主要综述了氮沉降对森林植物化学元素、植物生长、植被多样性、森林土壤动物生物量和多样性、森林微生物的影响,森林生态系统中造成氮沉降原因及解决措施,并对今后的生态系统研究工作提出展望。为氮沉降相关问题的研究提供参考。

The increasing amount of atmospheric and soil nitrogen deposition in soil,plant and atmospheric system(SPAC)changes the regional and global environment,which seriously affects the material cycle,energy conversion and information transmission between organisms and the environment in the existing forest ecosystem.This paper mainly summarizes the effects of nitrogen deposition on forest plant chemical elements,plant growth,vegetation diversity,forest soil animal biomass and diversity,forest microorganisms,the causes and solutions of nitrogen deposition in forest ecosystem,and puts forward the prospect of future ecosystem research work.To provide reference for nitrogen deposition related issues.
