Canada contains approximately 10% of the world's forests and approximately 25% of world's boreal forests. Boreal forests are especially vulnerable to climate change and ecosystem disturbances due to the longevity of the life of its trees and the extent of expected climate change within their life span. Changes in climate and resultant increases in ecosystem disturbances are expected to significantly alter future forest growth and production, greenhouse gas emissions and budgets in Canada. The future role of Canadian forest ecosystems in the global greenhouse gas budget is very important for policy makers considering the urgency and mechanisms for controlling greenhouse gas (GHG) emissions and potential adaptation strategies. There is an urgent need to develop a better scientific understanding and to quantify the impacts of future climate change on forest ecosystems in Canada, including ecosystem productivity, GHG (CO2, CH4, N2O) budgets, and changes in the timing and magnitude of fluxes between the land and the atmosphere. The central objective of this research program is to develop and use state-of-the-art computer simulation models for full accounting of the GHG budgets in Canada’s forest soils and investigating the impacts of future climate change on the GHG budgets of forest soils across Canada. This program will develop an original and innovative approach to address the increasingly important issues of climate change mitigation and adaptation as well as greenhouse gas emission reduction targets. This research program will train 14 highly qualified personnels (including 1 Post-doctoral, 2 Ph.D, 1 Master, and 10 undergraduate students with expertise in state-of-the art modeling, analytical and statistical methods and GHG budget accounting). The outputs of this research will fill the information gaps needed by foresters, forest managers, and policy-makers from federal agencies, local governments, forest industry and private companies for the ongoing negotiation of the Kyoto Protocol, developing GHG-based indicators for sustainable forest management, and mitigation and adaptation strategies in Canada.

加拿大约有大约10％的世界森林和世界北方森林的25％。由于其寿命的寿命以及其寿命内预期的气候变化程度，北方森林特别容易受到气候变化和生态系统灾难的影响。预计气候变化和生态系统灾害的增加将显着改变未来的森林增长和生产，加拿大的温室气体排放和预算。加拿大森林生态系统在全球温室气体预算中的未来作用对于考虑控制温室气体（GHG）排放和潜在适应策略的紧迫性和机制非常重要。迫切需要建立更好的科学理解，并量化未来气候变化对加拿大森林生态系统的影响，包括生态系统生产力，GHG（CO2，CH4，N2O）预算，以及土地和大气之间的磁通量的时机和幅度的变化。 该研究计划的核心目的是开发和使用最先进的计算机模拟模型，以充分考虑加拿大森林土壤中的温室气体预算，并研究未来气候变化对加拿大森林土壤温室气体预算的影响。该计划将开发一种原始和创新的方法，以解决降低气候变化和适应以及温室气体排放量的越来越重要的问题。该研究计划将培训14名高素质的人员（包括1名博士后，2名博士学位，1名硕士和10名本科生，并具有最先进的建模，分析和统计方法以及GHG预算会计方面的专业知识）。这项研究的产出将填补来自联邦机构，地方政府，森林行业和私人公司的林业人员，森林经理和政策制定者所需的信息空白，以进行京都协议的持续谈判，为加拿大加拿大加拿大的基于温室气体的可持续森林管理以及缓解和适应策略制定基于温室气体的指标。
