Collaborative Reseach: Effects of Climate-Landscape Interactions on Soil Carbon Storage and Cycling in Arctic Alaska

粤ICP备16015947号-1 Brubaker，琳达华盛顿大学 密歇根州乔治大学KLING 明尼苏达大学-双城分校 研究人员将研究气候强迫和景观特征对阿拉斯加北极中部山麓植被覆盖和土壤碳储存演变的作用。结合现场方法，建模和古重建将被用来确定不同年龄景观生态系统过程的空间变化。 这项研究的结果将提供一个指标，预计变化的碳平衡在北极地区由于冻土带生态的变化，作为全球气候变化的结果。 这项研究对于了解冻土带作为陆地碳源或库的作用非常重要，这些碳可能在拟议的温室气候条件下添加到大气中或从大气中提取。

OPP-9615947 BRUBAKER, LINDA UNIVERSITY OF WASHINGTON OPP-9615986 KLING, GEORGE UNIVERSITY OF MICHIGAN OPP-9616288 HU, FENG UNIVERSITY OF MINNESOTA-TWIN CITIES Researchers will examine the role of climate forcing and landscape character on the evolution of vegetation cover and soil carbon storage in the central Arctic foothills of Alaska. A combination of field methods, modeling and paleoreconstruction will be used to determine the spatial variation of ecosystem processes on different age landscapes. The results of this study will provide an indication of expected changes to the carbon balance in the arctic due to changes in tundra ecology as a result of global climate change. The study is important for understanding the role of tundra as a source or reservoir of terrestrial carbon that may be added to or extracted from the atmosphere under proposed greenhouse climate conditions.
