Carbon dynamics in Canada's managed forests from 1991 to 2006: A comparison of InTEC and CBM-CFS | Posted on:2010-09-06 | Degree:M.Sc | Type:Thesis | University:University of Toronto (Canada) | Candidate:Zhang, Beiping | Full Text:PDF | GTID:2443390002983726 | Subject:Climate change | Abstract/Summary: | | This study examined the annual C balance and its shifting trend in Canada's managed forests from 1991 to 2006 using the Integrated Terrestrial Ecosystem C-budget (InTEC) model. During this period, Canada's managed forests remained a moderate C sink of 58 Mt C yr-1 on average, but displayed an apparent trend of shifting towards a C source. The combined risk of climate change and increased disturbances are weakening the C sink in Canada's managed forests.;This study also compared the results from InTEC with those from CBM-CFS (Carbon Budget Model of the Canadian Forest Sector) at both national and regional levels. InTEC shows larger inter-annual variability and regional difference than CBM-CFS due to its incorporation of both disturbance and non-disturbance factors. In comparison, CBM-CFS3 has likely underestimated both the true C loss and the C sink potential of Canada's managed forests, given that it does not account for the non-disturbance factors. | Keywords/Search Tags: | Managed forests, Canada, CBM-CFS, Climate change, Non-disturbance factors | | Related items |
