Abstract Rapid warming of Arctic climate is driving complex ecological changes in Arctic terrestrial ecosystems that are not well understood. These ecological changes have important implications for northern communities and Arctic ecosystem resilience. Researchers require baseline information on tundra ecosystem compo sition, structure and function at a range of scales to begin to understand how and why tundra ecosystems are changing to anticipate future changes and their impacts. Here we develop and assess a process for obtaining a high-resolution ecosystem map of terrestrial ecological communities for the Intensive Monitoring Area (IMA) of the Canadian High Arctic Research Station (CHARS) in Cambridge Bay, Nunavut. The methodology is based on a standardized classification of tundra ecosystems, and will provide an ecological template for designing and implementing ecosystem research, long-term monitoring experiments, and for linking local scale research to regional scales using remote sensing tools and models. Finally, we discuss opportunities and challenges regarding the mapping approach tested for the ecosystem classification, and the usefulness of the mapped result for a range of potential applications.

努纳武特维多利亚岛苔原生态系统的高分辨率测绘——标准化陆地生态系统分类的应用

摘要 北极气候的快速变暖正在推动北极陆地生态系统发生复杂的生态变化，而这一变化尚不清楚。这些生态变化对北方社区和北极生态系统恢复力具有重要意义。研究人员需要有关各种尺度的苔原生态系统组成、结构和功能的基线信息，以开始了解苔原生态系统如何以及为何发生变化，以预测未来的变化及其影响。在这里，我们开发并评估了一个过程，用于获取位于努纳武特剑桥湾的加拿大高北极研究站 (CHARS) 的密集监测区 (IMA) 陆地生态群落的高分辨率生态系统地图。该方法基于苔原生态系统的标准化分类，将为设计和实施生态系统研究、长期监测实验以及使用遥感工具和模型将局部尺度研究与区域尺度联系起来提供生态模板。最后，我们讨论了为生态系统分类测试的映射方法的机遇和挑战，以及映射结果对一系列潜在应用的有用性。
