Climate Change Mitigation Potential in Boreal Forests: Impacts of Management, Harvest Intensity and Use of Forest Biomass to Substitute Fossil Resources

摘要: The impacts of alternative forest management scenarios and harvest intensities on climate change mitigation potential biomass production, utilization economic profitability production were studied in three boreal sub-regions Finland over a 40-year period. Ecosystem modelling life cycle assessment tools used to calculate the substituting fossil materials energy, expressed as net CO2 exchange. Currently recommended targeting timber acted baseline management. Alternative included maintaining 20% higher or lower stocking forests final felling made at breast height diameter than baseline. In scenarios, logging residues with coarse roots stumps harvested addition timber. exchange southern eastern was compared western one due ecosystem (NEE) study Maintaining earlier intensified appeared be best option increase both benefits returns. Trade-offs between highest existed. use displacement factors largely affected biomass.
