Abstract
The invention provides a biomass carbon emission estimation system and method based on life cycle analysis. The system includes: a data acquisition module for receiving the measured actual data; A knowledge base for storing vegetation carbon dynamics models, calculation formulas involved in each module, and parameter values involved in the calculation process; a Database for storing the actual data obtained from measurement, intermediate data and calculation results in the calculation process of each module; a Carbon emission estimation module, including: fossil energy carbon emission, land use change carbon emission, biomass carbon emission and biomass use carbon emission estimation sub-module; Each sub-module obtains the measured data from the database and calculates the carbon emissionwith the calculation formula in the knowledge base. The total carbon emission estimation module retrieves the calculation results of the carbon emission estimation module in the carbon emission estimation module from the database to estimate the total carbon emission. The invention fully considers the carbon emission of the whole process of the biomass in the life cycle analysis, and can truly estimate the carbon emission of the biomass.
Description
technical field [0001] The present disclosure relates to the technical field of biomass carbon emission estimation, in particular to a system and method for estimating biomass carbon emission based on life cycle analysis. Background technique [0002] In the face of global warming, biomass energy is favored because of its low carbon emissions, and the use of biomass energy has also received strong support from the government. [0003] At present, there is no systematic product for the estimation of biomass energy carbon emissions, and the analysis method adopted is life cycle analysis as the standard method, but the current mainstream life cycle analysis only calculates the fossil energy in the process of biomass processing and production. carbon emissions from biomass energy utilization, ignoring the carbon emissions caused by land use changes, carbon emissions from biomass energy combustion, and carbon sequestration loss caused by biomass energy utilization, so that the ca...
