【 摘 要 】

The Agriculture and Agri-Food’s Biomass InventoryMapping and Analysis Tool (BIMAT) provides internetbased GIS functionality to query and visualize biomassinventory data in Canada. The Integrated Biomass SupplyAnalysis and Logistics (IBSAL) model is a modularizedsimulation of biomass supply chain. In this study, IBSALmodules are assembled to simulate harvesting of straw,stover, and switchgrass yields. The operations in this studystarted from combining for grain crop residues and ended instacking bales on the field side. The equation C=aR^b Y^cwas fitted to the simulated data to estimate constants a, b,and c for cost in $/dry tonne, energy input in MJ/dry tonne,and carbon emissions in kg CO2/dry tonne. Variable R isthe fraction of above ground biomass removed duringharvest and Y is the yield defined as biomass above ground(dry tonne/ha). These functions are supplied to the BIMATportal and developed specific values for costs, energy input,and emissions on the map. The farm gate cost cost for thestacked bales ranged from $20 per dry tonne for highyielding regions of southwest Edmonton and Ontario to $27per dry tonne for the eastern Ottawa region, and $31 per drytonne for low yielding regions of central Saskatchewan. Thecosts are validated with published custom rates. It isrecommended that the next step is to integrate IBSAL andBIMAT codes so the logistics values are generated andshown automatically on the map.
