Abstract:

Selection of algorithms for forest fire spreading simulation is important. In this paper, the traditional boundary interpolation algorithm is optimized and then compared with the maze algorithm in forest fire spreading simulation. The results are the following. The maze algorithm consumes more time (204、458、1325 s) than the boundary interpolation algorithm (5、7、16 s). The time consumed by the maze algorithm will doubly increase;As far as accuracy of simulation results concerned, the boundary interpolation algorithm has a lower accuray(59.75%) than the maze algorithm, but it shows simple changes of the forest fire spreading generally. Results obtained from maze algorithm provide more detailed information for the forest fire spreading and it resembles closely to actual spreading area.
