【摘要】 建立了森林火灾地面扑救方式(直接扑救、间接扑救和平行扑救)的最佳扑救路线的数学模型,设计了模型的计算机数值求解算法。给出了匀速扩张的椭圆形火场的一个算例,从其计算结果中导出的一些实用的结论与以往用解析方法得到的结论是一致的,以此初步验证了模型的有效性。更多还原

【Abstract】 The paper sets up a mathematical model for forest fire fighting on the ground (direct attack, indirect attack and parallel attack) to get the best attack route, and designs its numerical algorithm on computer. A calculation case of elliptic fire shape expanding at invariable speed is presented. The practical conclusions deduced from the result accord with those from analytic solution in previous literature, which preliminarily validates the model.更多还原
