| 1 | 北方沼泽地水位下降对全球气候变暖的影响显示文摘自从最后一次冰川消退以来,北方沼泽地(3.46亿hm^2)积存了300~500Pg碳。这些沼泽地在分离二氧化碳(CO_2)的同时,释放了相当数量的甲烷(CH_4)到大气中。正如对高纬地区预报的那样,如果夏季变得更热、更干,未来沼泽地温室气体的平衡将发生变化,随之而来的CH_4排放将减少,而CO_2和N_2O的排放将增加。北部沼泽地水位下降预计将增强温室效应的影响。我们分别在不同营养水平的未排水和排水的沼泽地测量了碳循环的组分,并把这些结果归纳成一个简单的辐射强迫因子,用以评价水位下降对大气的综合影响。在对存于土壤和树木中的碳以及为经营森林而排水引起的水位下降后CO_2、CH_4和N_2O的通量的变化作出测量的基础上,我们提出一个假设,即由气候变化引发的干旱趋势将减弱北方沼泽地对总辐射强迫的影响,这一影响在100年内约为0.1W/m^2。CH_4排放的减少,沼泽地碳储量的微小变化和树木生物量储存的增加都将导致这一变化。 | Jukka Laine Jouko Silvola Kimmo Tolonen Jukka Alm Hannu Nyknen Harri Vasander Tapani Sallantaus Ilkka Savolainen Jukka Sinisalo Pertti J.Martikainen 钱云 | 1996 | 人类环境杂志1996，25，3： | 4 |
