摘　　要：利用水泵进行灭火作战的技战术已相对丰富完善,但是对于搭建供水系统缺少实用的理论依据支撑。本文通过明确森林火灾水泵供水干扰因子,为研究水泵供水策略提供理论依据。通过建立供水系统并设计试验计算得出森林消防队伍广泛使用的25-40-30涤纶长丝/涤纶长丝-聚氨酯水带阻抗系数,根据伯努利原理,对火场供水系统能量转换进行分析,经过推导得到单泵连接水带数量公式、架设水泵数量公式、最少投入装备数和一次性投入最大有效兵力数。一线指战员可根据单泵连接水带数量公式、架设水泵数量公式快速搭建供水系统,前指与基指指挥员则可参考最少投入装备数和一次性投入最大有效兵力数制定灭火作战计划。The techniques and tactics of using water pump for fire fighting have been relatively rich and perfect,but there is a lack of practical theoretical basis for building water supply system.This paper provides a theoretical basis for studying water supply strategy of water pump by clarifying the interference factors of water pump supply in forest fire.Through the establishment of water supply system and design test,the impedance coefficient of 25-40-30 polyester filament/polyester filament/polyurethane hose widely used by forest fire fighting teams was calculated.According to Bernoulli principle,the energy conversion of fire water supply system was analyzed.The formula of the number of connected water belts,the formula of the number of erected water pumps,the minimum number of equipment and the maximum number of effective forces at one time were derived.The front-line commanders can quickly build the water supply system according to the number formula of the single pump connected hose and the number formula of the erected pump,and the front and base commanders could draw up the fire fighting plan by referring to the minimum number of equipment invested and the maximum number of effective troops invested at one time.
