该项目将支持一项跨越30多年的综合研究,重点是北方森林的树木年轮分析。 北美和欧亚大陆的北方森林生态系统是地球碳循环的高度敏感指标。在过去几十年中,这些森林提供了关于北方森林生长变化以及上个千年气候和环境变化的宝贵信息。该项目将产生两个主要产品。首先,一个全面的,广泛使用的专题论文,将综合这一广泛的机构的树木年轮分析,从北方森林与全球变化研究。 这本专著将研究所谓的“发散效应”,这意味着要弄清楚近几十年来树木生长和温度模式在北方许多地方是如何以及为什么不一致的。记录这种趋异效应对于识别和理解未来气候变化对树木生长的影响至关重要。 第二,将在汇编长期树木年轮数据、描述和重建的基础上制作一个光盘地图集。该光盘产品将提供给世界各地的研究人员和学生,并将提供有关科学现状的重要观点,并为学校课程的编制提供材料。 这份综合报告提供了对科学决策过程的深入了解,并与关注全球变化及其影响的决策者有关。
英文摘要
This project will support a synthesis spanning more than three decades of research, focused on tree-ring analyses of northern forests. The northern forest ecosystems of the great land masses of North America and Eurasia are highly sensitive indicators of the Earth's carbon cycle. Over the past decades, these forests have yielded valuable information on variation in boreal forest growth as well as climatic and environmental change for the past millennium. Two main products will result from this project. First, a comprehensive, widely-accessible monograph that will synthesize this extensive body of tree-ring analysis from northern forests related to global change studies. The monograph will examine the so-called 'divergence effect', which means figuring out how and why tree growth and temperature patterns are not lined up at many northern sites, in recent decades. Documenting the divergence effect is critical for identifying and understanding the implications of future climate change on tree growth. Second, a CD atlas will be produced based on compilation of long-term tree-ring data, descriptions and reconstructions. This CD product will be made available to researchers and students worldwide and will provide important perspectives regarding the state of the science and provide materials for development of school curricula. This synthesis provides insights into the scientific decision-making process and is relevant to policy makers concerned with global change and its impacts.
