The quantitative relations between the stretching speed of the forest fire and the wind and re-lief are given.An equation set for predicting the speed of the forest fire spreading is developed.Through the actual tests,it is found that this method is favourable for the operational use.

给出了风和地形对林火蔓延速度作用的定量关系以及适合于业务使用的计算林火蔓延速度的方程组。经实地点火对比验证,该方法有一定实用价值。

In this article,fractal theory is applied to further study the spread of forest fires,the fractal relations under variable wind velocities,wind directions, and level and isotropic fuel beds are analysed A fractal model is presented on the basis of self-similarity of ractal curve and the fea-ture of the uneven boundary of fire field.A area formula of fire field is dedused from 1.2618 coch cu rve, It turns out that average errors of relative values,are small.the wider a fire field...
