Occurrnce and spreading of forest fire are closely related with climatic conditions. The zoning is worked out by the theory and method of modern climatic zoning. In the zoning the indexes are defined from grades of fire hazard which are calculated by method of multiple factor aggregative indexes. The zoning can provide a reliable climatic foundation and background for fire protection programme and for forest fire weather forecast. It is of some practical va...             森林火灾是森林资源的重大灾害。而林火的发生、蔓延与气候条件密切相关。此区划是按照多因子综合指标法计算的火险等级而确定的指标,用现代气候区划理论与方法完成。可为制订森林防火、灭火规划及林火气象预报提供可靠的气候依据和气候背景。 文摘来源          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.             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。 文摘来源   << 更多相关文摘         相关查询: 森林防火 森林防火期 森林防火林带 森林防火对策 森林防火管理 森林防火服 森林防火资源 森林防火学 森林防火鞋 森林防火系统 森林防火工程体系 防火  对查询结果不满意
