Canadian forest resources and closely-linked watershed ecosystems are undergoing significant change mainly due to increased large-scale forest disturbance, post-disturbance reforestation and climate change impacts. This research focuses on how reforestation affects two important and strategic processes, forest carbon and water, and their interactions across different spatial scales (tree, forest stand and watershed levels). Previous research has placed an emphasis on forest carbon and water coupling at an individual spatial scale, with rare attention on cross-scale comparisons. While experiments (e.g., leaf gas exchange, sap flow measurement) will be used at the tree level, a modeling approach will be implemented at the forest stand (FORECAST-Climate) and watershed (RGESSys) scales. Such a complementary and combined approach will provide a robust research framework for addressing the research objectives. Three graduate and 3 undergraduate students will be trained. This collaboration will greatly strengthen our research and management capacities in dealing with forest carbon and water resource changes, and place our Canadian industries in an advantageous position in the globe.

加拿大森林资源和紧密联系的流域生态系统正在发生重大变化，这主要是由于大规模的森林骚乱，旱灾后造林和气候变化的影响。这项研究的重点是造林如何影响两个重要的战略过程，即森林碳和水，及其在不同的空间尺度（树，森林站和流域水平）上的相互作用。 先前的研究重点是在单个空间尺度上对森林碳和水耦合，很少关注跨尺度比较。 尽管将在树级使用实验（例如，叶子气体交换，SAP流量测量），但将在森林林（预测气候）和分水岭（Rgessys）尺度上实施建模方法。这种互补和合并的方法将为解决研究目标提供强大的研究框架。将对三名毕业生和3名本科生进行培训。这种合作将极大地增强我们在处理森林碳和水资源变化方面的研究和管理能力，并使我们的加拿大行业处于有利的地位。
