1. The dangers of forest fires

Forest fires are the most dangerous enemy of forests and the most terrifying disasters in forestry. Bringing the most harmful and devastating consequences to the forest. Forest fires not only burn down vast areas of forest and harm the animals in the forest, but also reduce the forest's renewal capacity, cause soil infertility, destroy the forest's role in water conservation, and even cause the ecological environment to lose balance. Although science in today's world is advancing at a rapid pace, humans have still not made long-term progress in controlling forest fires.

2. Types and classifications of forest fires

Based on the burning location of forest fires, the speed of spread, and the location and extent of damage, forest fires can be roughly divided into three categories: First, surface fires 2. Crown fire and 3. underground fire.

Based on the size of the affected forest area, forest fires are divided into the following four categories:

1. Forest fire: The affected forest area is less than 1 hectare or other forest fires (including wild fires) ;

2. General forest fire: the affected forest area is more than 1 hectare but less than 100 hectares;

3. Major forest fire: the affected forest area is more than 100 hectares but less than 1,000 hectares;

4. Extremely large forest fires: the affected forest area is more than 1,000 hectares;

3. Causes of forest fires

There are two main causes of forest fires Category: Man-made fire and natural fire:

(1) Man-made fire includes the following types:

1. Productive fire source: fire used in agriculture, forestry and animal husbandry production, forest Fire used in sideline production, industrial, mining and transportation production, etc.;

2. Non-productive fire sources: such as outdoor smoke, cooking, burning paper, heating, etc.;

3. Intentional arson

Among the fires caused by man-made fire sources, forest fires caused by reclamation and burning, smoking, etc. are the most common. Among the forest fires in our country, fires caused by cooking smoke, burning wasteland and burning paper at graves account for an absolute number.

(2) Natural fire: including lightning fire, spontaneous combustion, etc. Forest fires caused by natural fires account for about 1% of the total number of forest fires in my country.

Three factors affecting fire

Temperature, humidity and unit flammable load.

4. The discovery of forest fires - discovery is more meaningful than extinguishing

Forest fires are very harmful and difficult to extinguish, so it is particularly important to extinguish the fire immediately when it is still in its infancy. .

Because forest fires often occur in deep mountains and old forests, they are difficult to detect. Therefore, detecting fires is of great significance for putting out fires early.

There are still many technologically backward methods in China.

1. Build a lookout tower

Observation tower monitoring is to observe the occurrence of forest fires through lookout towers, determine the location of the fire, and report the fire situation. Its advantage is that it has a wider coverage area. Large and effective. Existing shortcomings: observation towers cannot be set up in remote forest areas without living conditions; its observation effect is limited by the topography, the coverage is small, there are dead corners and blank spaces, and it cannot be observed. It is difficult to observe large-scale fire scenes and residual areas with heavy smoke Fire and underground fire cannot be observed; it is impossible to go up to the tower to observe in thunder and lightning weather; observation is a method that relies on the experience of the lookout, with low accuracy and large errors. In addition, the personal safety of lookouts is threatened by lightning, wild animals, forest encephalitis, etc.
