| 摘 要： | 地表火蔓延状况的预测预报是森林防火灭火工作中的一项重要技术。目前，国外在预测火场扩展边界的形状及分布时采用了火场椭圆面假设，当可燃物、地形或气象条件复杂变化时，预测结果偏差较大。本文从地表火蔓延的本质入手，建立起确定复杂地形、气象条件和可燃物分布情形下的火蔓延边界的数学模型，并借助于现代软件编制技术，成功地编制出预测预报地表火蔓延边界的图形显示系统，率先实现了对任意情形下火蔓延边界的合理、准确的估算。

| Abstract: | Based on the understanding Of the nature of fire spread over surface fuels, in this paper amathematical model has been developed for determining ground fire boundaries under the condi-nons of complicated fuel types, changing terrain and weather. By means of modern softwarecompiling techniques, a graphically - displa yed syste m h as been successfully estabtish d, whichrealize accurate estimations of ground fire boundaries in any circumstances. |
