Abstract森林是重要的陆地生态系统碳汇。1990–2007年间全球森林平均每年从大气中吸收固定2.4±0.4PgC,但对全球森林未来固碳量的评价多是基于气候因素的过程模型的模拟结果,很少有基于森林调查样地数据评价全球森林固碳潜力的研究。我们收集整理野外调查和已发表的成熟林生物量数据728条,建立全球成熟林生物量数据库。根据成熟林地上生物量碳储量空间插值,得到全球森林地上生物量碳容量,进而评估全球森林地上生物量的固碳潜力。结果显示:(1)全球成熟林地上生物量自赤道向两极整体呈递减趋势,但最大值出现在中纬度区;(2)气温和降水是影响成熟林地上生物量的重要因素;(3)全球森林地上生物量碳容量约为586.2±49.3PgC,其地上生物量固碳潜力为313.4PgC。因此,充分发挥现有森林的碳吸存能力,减少对现有森林碳库的干扰,是土地利用变化之外减缓温室气体排放的又一可选途径。
