| 中文摘要: |
| 本文从森林地表火蔓延的本质入手，提出了火场扩展的“点义源原理”，并在此基础上建立了一套完整的确定动态火场蔓延边界的新模型。对若干算例试算的结果表明，模型对可燃物类型、地形和气象条件复杂变化下的火场边界的确定，能获得相当合理的图形显示的结果。 |
| 英文摘要: |
| Started with the mechanism of fire spread over ground fuels ,a principlea a fire boundary ex-tention has been summized, On the basis,a model has been established for calaulating a spreadingfire boundary. Applied the model to some examples, it has shown that the model can give ratherreasonable and graphically displayed results for ground fires under the conditions of nonuniformfuels, changing terrain and weather. Moreover,the model can also give reasonable and reliabledistributions of fire boundaries, for the circumstance of the existance of barrier or non fuels zonearound thefire. |
