ABSTRACT OPP-9630913 STARFIELD UNIVERSITY OF MINNESOTA-TWIN CITIES The proposed research will address a major problem in climate change research in the Arctic. The role of shifts in treeline due to past climate change will be examined using the relationships of modern treeline position with measured climate variables. The results from the study of predicted response of treeline position to climate changes in the past will then be used to examine future changes that could take place due to proposed climate changes in the future. The consequences of feedbacks to climate change due to the movement of the treeline is important to ascertain so that management and policy decisions can be made concerning the impacts of global change and other disturbance factors on human use of forest resources in the Arctic.

摘要 明尼苏达州斯塔菲尔德大学-双城 这项拟议中的研究将解决北极气候变化研究中的一个主要问题。由于过去的气候变化，在树线的变化的作用将使用现代树线的位置与测量的气候变量的关系进行检查。研究结果预测的树线位置对过去气候变化的反应，然后将用于审查未来的变化，可能会发生由于未来的气候变化。 必须确定由于树线移动而对气候变化的反馈的后果，以便就全球变化和其他干扰因素对人类利用北极森林资源的影响作出管理和政策决定。
