Strategic forest management planning models designed to maintain existing carbon stocks and maximize capacity for future sequestration can help identify underused opportunities to increase carbon stocks without diminishing other forest products. This study proposed a carbon stock unit that allows summing up the stocks in the different forest pools even if the decomposition far exceeds the planning horizon. This unit is used to integrate the methods and algorithms from the Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3) model into a wood supply model. The resulting model could be used to predict changes in carbon stocks, transfers between carbon pools, and greenhouse gas emissions that would result from every forest management activity. We tailored this model to meet different strategies: maximizing carbon storage in the forest, maximizing high-sustained timber yield, and achieving the dual objectives of yield and carbon storage. A range of management scenarios were simulated using the data of a 485,000 hectares mixed-wood forest in Quebec, Canada. Our results demonstrate that, with the reduction in the harvest rates, the increase in the ecosystem carbon storage is insufficient to offset the carbon losses associated with the increase in the harvest rates.

优化木材产量和碳固存的战略森林管理模型

战略性森林管理规划模型旨在维护现有的碳储量并最大程度地增加未来的封存能力，可以帮助发现利用不足的机会来增加碳储量而不会减少其他森林产品。这项研究提出了一个碳储量单位，即使分解远远超出了规划范围，该单位也可以汇总不同森林池中的储量。该单元用于将加拿大森林部门碳预算模型（CBM-CFS3）模型中的方法和算法集成到木材供应模型中。所得模型可用于预测碳储量的变化，碳库之间的转移以及每项森林经营活动都会导致的温室气体排放。我们根据不同的策略量身定制了该模型：最大化森林中的碳存储量，最大限度地提高木材的可持续产量，并实现产量和碳储量的双重目标。使用加拿大魁北克485,000公顷的混合木森林的数据对一系列管理方案进行了模拟。我们的结果表明，随着收割率的降低，生态系统碳储量的增加不足以抵消与收割率增加相关的碳损失。
