摘要：Bushfire has been classified into several burning zones for easily modeling according to remote sensing imagery. Estimating mass and heat transport released from an individual large scale bushfire has been implemented in detail by means of integrating knowledge of transport phenomena with hybrid technique of combining features of digital elevation model and remote sensing imagery. The multi-component smoke has been treated as single-component substance. Mass diffusion takes place in a smoke –air binary system. The effective semi-infinite model has been effectively selected. The basic theories in mass diffusion and heat conduction has been reviewed and applied into calculating distribution of pollutant concentration and temperature profile of bushfire, and analysing emission rate of mass and energy using one chosen geographical location respectively.
