森林生态系统的可持续性和气候变化是加拿大北方森林生态系统的两个关键问题，需要了解生产力，土壤过程及其与自然和人为干扰的相互作用之间的联系和平衡。森林生态系统模型可用于了解和预测北方森林生态系统动态。EFIMOD 2是一个森林土壤生态系统的单树模型，能够模拟土壤水分和温度变化对生产力的氮反馈。它已在欧洲成功应用，但尚未在加拿大的任何森林生态系统中进行校准。本研究的目的是参数化并验证加拿大短叶松的EFIMOD 2。模拟和测量结果同意树木生物量碳和土壤碳和氮的变化，随着林龄的增加，并在整个气候梯度从南部到北方界限的北方森林。初步结果从场景测试indic.
Sustainability of forest ecosystems and climate change are two critical issues for boreal forest ecosystems in Canada that require an understanding of the links and balance between productivity, soil processes and their interaction with natural and anth ropogenic disturbances. Forest ecosystem models can be used to understand and predict boreal forest ecosystem dynamics. EFIMOD 2 is an individual tree model of the forest-soil ecosystem capable of modelling nitrogen feedback to productivity in response to changes in soil moisture and temperature. It has been successfully applied in Europe, but has not been calibrated for any forest ecosystem in Canada. The objective of this study was to parameterize and validate EFIMOD 2 for jack pine in Canada. Simulated and measured results agreed for changes in tree biomass carbon and soil carbon and nitrogen with increasing stand age and across a climatic gradient from the southern to northern limits of the boreal forest. Preliminary results from scenario testing indic...
