答、破壞森林的燃燒條件，不讓可燃物、氧氣和火源（森林燃燒三要素)結合在一起，只要消滅燃燒三要素中得任何一個，森林火災就會熄滅

A. destroy the burning conditions of the forest, and do not allow combustible materials, oxygen and fire sources (three elements of forest combustion) to be combined. As long as any one of the three elements of combustion is eliminated, the forest fire will be extinguished

撲滅森林火災的根本途徑是；

The basic way to put out forest fire is to put out forest fire;

（1）隔離可燃物，是著火的可燃物與未著火的可燃物隔離（如開挖防火阻隔帶），達到控制、撲滅林火的目的；

(1) Isolation of combustibles refers to the isolation of on fire combustibles and unburned combustibles (such as excavation of fire barrier belt) to control and extinguish forest fires;

（2）隔離氧氣，減少森林燃燒物所需要的氧氣，使其窒息熄滅（如以土覆蓋滅火法）

(2) Isolation of oxygen to reduce the oxygen required for forest combustion to suffocate and extinguish (e.g., covering fire with soil)

（3）冷卻降溫，使燃燒可燃物的溫度降到燃點一下，林火停止燃燒（如以水滅火法）。

(3) Cool down to lower the temperature of combustible materials to the point of ignition, and the forest fire will stop burning (e.g. fire extinguishing by water).
