Forest carbon and water coupling in a large Canadian forested watershed

在加拿大以森林为主的流域，森林碳(C)和水对于管理气候变化影响和保护水生生态系统至关重要。在加拿大的景观中，迫切需要了解森林碳和水是如何整合或耦合的，以及它们在不同空间尺度上对森林干扰的反应。在这项拟议的研究中，我们将使用加拿大CBM-CFS3模型和我们成熟的水文方法来评估森林干扰对不列颠哥伦比亚省内陆一个大流域(Deadman河流域：600平方公里)森林C-水耦合的影响。在利用CBM-CFS3模型研究森林碳动态的同时，将进行水文分析来量化森林的C-水耦合。在这项研究之后，UBC和我们的合作伙伴Ecora将联合提交一份单独的建议(NSERC CRD)，目的是研究森林干扰如何影响不同空间尺度(森林林分、小流域和大流域)的森林C-水耦合。

In forest dominated watersheds of Canada, both forest carbon (C) and water are critical for managing climate change impacts and protecting aquatic ecosystems. Understanding how forest C and water are integrated or coupled and their responses to forest disturbance at different spatial scales is urgently needed in Canadian landscapes. In this proposed research, we will use a combination of the Canadian CBM-CFS3 model with our well-established hydrological methodology to assess the effects of forest disturbance on forest C - water coupling in a large watershed (Deadman River watershed: 600km2) in the BC interior. While the CBM-CFS3 model is used for developing forest C dynamics, the hydrological analysis will be conducted to quantify forest C-water couplings. Following this study, UBC and our partner, Ecora, will jointly submit a separate proposal (NSERC CRD) for the purposes of studying how forest disturbance affects forest C-water couplings at various spatial scales (forest stand, small watershed and large watershed).
