项目摘要
Over the next five years, the proposed work will examine the processes that control the exchange of carbon dioxide, water, and energy from selected sites in the Canadian boreal forest zone. A particular emphasis of the work is to study the impact of disturbance and silvicultural practices on the ability of the forest to sequester (capture and store) carbon dioxide. We will measure the fluxes (exchange rates) of carbon, water, and energy (CWE) between the atmosphere and the forest, examine how these fluxes change with season and from year-to-year, and develop a scheme to scale the flux of carbon dioxide from the site to the regional level. The work will contribute to the development of ecosystem models of carbon exchange and to models used to simulate the impact of climate change. Such work is basic to our ability to understand how the likely future climate change will impact our forests. Experiments will be conducted at sites in northern Ontario and northern Saskatchewan. In Ontario, the work will focus on the mixedwood forests located near Timmins. Three sites will be studied: a logged site, a juvenile, improved mixedwood site (17 years old), and an old, fully mature site (76 years old). In Saskatchewan, the experimental work will be conducted on a range of jack pine forest sites that are part of the Boreal Ecosystem Research and Monitoring Sites (BERMS) project. The selected sites are part of a chronosequence representing a series of stages of tree growth from juvenile (12 years old) to mature (31 years old) to old (90 years old). In studying a chronosequence we assume that we can recreate the trajectory of the changing CWE fluxes as the forest regrows after a disturbance. Effectively, we substitute space for time.The proposed work will support the training of two undergraduate students each year as summer research assistants. Two graduate students per year (either Masters or doctoral levels) will be trained. One post-doctoral candidate has been accepted for the first year of the grant and at least one more pdf is anticipated later in the funding period. I plan to train one data analyst.
在接下来的五年里,拟议的工作将研究控制加拿大北方森林区选定地点的二氧化碳、水和能量交换的过程。这项工作的一个特别重点是研究干扰和造林做法对森林隔离(捕获和储存)二氧化碳能力的影响。我们将测量大气和森林之间的碳,水和能量(CWE)的通量(交换率),研究这些通量如何随季节和年复一年的变化,并制定一个计划,将二氧化碳通量从现场扩展到区域水平。这项工作将有助于开发碳交换的生态系统模型和用于模拟气候变化影响的模型。这些工作对于我们了解未来可能的气候变化将如何影响我们的森林的能力至关重要。实验将在安大略省北方和萨斯喀彻温省北方的研究中心进行。在安大略,工作重点是蒂明斯附近的杂木林。三个网站将进行研究:一个登录网站,少年,改进混合木材网站(17岁),和一个老的,完全成熟的网站(76岁)。在萨斯喀彻温省,实验工作将在北方生态系统研究和监测点项目的一系列短叶松森林地点进行,选定的地点是代表树木生长的一系列阶段的时间序列的一部分,从幼年(12岁)到成熟(31岁)到老年(90岁)。在研究一个时序,我们假设,我们可以重新创建的轨迹变化的CWE通量的森林重新生长后的干扰。实际上,我们用空间代替时间。拟议的工作将支持每年培训两名本科生作为暑期研究助理。每年将培养两名研究生(硕士或博士水平)。一名博士后候选人已被接受为赠款的第一年,至少有一个更多的pdf预计在资助期晚些时候。我打算培养一名数据分析师。
