国家级碳收支的研究为温室气体缓解战略的国家决策提供了一个定量的基础。对于包括俄罗斯在内的许多国家来说,与森林相关联的碳库和碳流是国家碳收支的重要组成部份。俄罗斯有8.84亿hm~2森林,估计在其活生物量中贮藏有42.1PgC,腐屑中贮有29.5Pg C,林产品中贮有2.9Pg C。在1988年至1993年期间,碳在活生物量中的贮量减少了0.5Pg,这是由于木材采伐(它超过了在生长树木中碳的积累量)、火灾和其它自然干扰的结果。被干扰的森林碳库中仅有一小部分碳直接释放进入大气层,较大部分被转入腐屑,而一部分则蓄积在林产品中。因缺乏这些关键性组合的数据,导致了碳流量估算中较多的不确定因素。俄罗斯森林在以碳固定为目的的经营方面具有很大的潜力。本文分析指出,森林经营措施能够在可持续基础上使俄罗斯森林未来的碳贮藏量水平增加2.0Pg C,约比目前水平提高2.8%。
Research on national carbon revenues provides a quantitative basis for national decisions on greenhouse gas mitigation strategies. For many countries, including Russia, carbon stocks and carbon flows associated with forests are important components of a country’s carbon budget. Russia has 884 million hm 2 of forest, and it is estimated that 42.1 Pg C is stored in its living biomass, 29.5 Pg C is stored in decoloration, and 2.9 Pg C is stored in forest products. Between 1988 and 1993, carbon reserves in live biomass decreased by 0.5 pg due to the effects of logging (which exceeded the accumulation of carbon in growing trees), fire and other natural disturbances. Only a small fraction of the carbon in the interfered forest carbon stocks is directly released into the atmosphere, the bulk of it is diverted to decay, and a portion is accumulated in forest products. The lack of data for these key combinations led to more uncertainties in carbon flow estimates. Russian forests have great potential for carbon-fixing operations. The analysis of this paper points out that forest management measures can increase the future carbon forest reserve in Russia by 2.0Pg C on a sustainable basis, about 2.8% more than the current level.
