人类活动在全球范围内极大地改变着氮素从大气向陆地生态系统输入的方式和速率,人为固定的氮素正在不断积累,并对生态系统的结构和功能产生显著影响。该文从以下几个方面综述了大气氮沉降增加对陆地生态系统的影响:1)氮输入增加可能影响植物生产力和生态系统碳蓄积能力,生态系统响应的方向和程度取决于系统的初始氮状况(氮限制或氮饱和)以及当地的植被和土壤特征;2)持续氮输入有可能改变土壤氮循环过程,降低土壤固持氮的能力,甚至导致土壤酸化、盐基离子损耗,进而影响到土壤有机碳的分解;3 ...

大气氮沉降可能会影响陆地生态系统的碳通量。本文主要目的是探讨在氮素缺乏的草地生态系统中,氮素添加是否会增加CO2通量。本研究于2008和2009生长季进行,采用静态箱-气相色谱法研究CO2通量对氮沉降增加的响应。结果表明,2年的氮素添加并没有显著影响土壤NH4+含量,NO3-含量只是在2009年生长季后期有所增加。高氮处理增加了CO2通量,而低氮处理在2008年抑制了CO2通量,2009年后期增加了CO2通量。而且氮素添加显著增加了地上生物量和根系的生物量。CO2通量与土壤水分 ...
