A complete collection of forest fire prevention knowledge

In the case of forest combustibles and fire sources, whether forest fires can occur mainly depends on fire weather. Generally speaking, fire weather is the climatic conditions favorable to forest fires, such as high temperature, little precipitation, low relative humidity, strong wind and long-term drought.

Forest fire is very harmful and difficult to put out, so it is particularly important to put out the fire immediately when the fire is still in its infancy. Because forest fires are often located in deep mountains and old forests, it is not easy to find them, so it is of great significance to find them early.

There are two main causes of forest fires: man-made fires and natural fires.

Man-made fire: Among the fires caused by man-made fire sources, forest fires caused by land reclamation and smoking are the most. In the forest fires in China, the fires caused by cooking smoke, burning wasteland and burning paper on graves account for an absolute number.

1. Productive fire sources: fire for agriculture, forestry and animal husbandry, fire for forestry sideline production, fire for industrial and mining transportation production, etc.

2. Unproductive fire sources: such as cooking in the wild, cooking, burning paper, heating, etc.

3. Intentional arson: burning hay, setting off firecrackers and fireworks.

Natural fire: including lightning fire and spontaneous combustion. Forest fires caused by natural fires account for about 1% of the total forest fires in China.

Importance of forest fire prevention

The survival and development of human beings can not be separated from the oxygen and forest products provided by forests for a moment. Although China has a vast territory and abundant resources, overall, the total amount of forest resources in China is still insufficient, and the forest coverage rate is only 60% of the world average, ranking130th in the world.

The per capita forest area is only 0. 13 hectare, which is less than the world average14, ranking134th in the world. The per capita forest stock is only 9.4 cubic meters, which is less than the world average 1/6, ranking122nd in the world.

Due to the insufficient total amount and low quality of forest resources, land desertification, soil erosion, drought and water shortage, floods and other disasters in China are very prominent, and the national ecological security is facing a serious threat. Among the threats affecting forest resources, forest fire is one of the most important threats, which can turn forests into ashes in an instant.

According to survey statistics, more than 95% of forest fires are caused by human factors. In order to keep the forest away from fire and people away from danger, the key is to let people know how to use fire scientifically, put out fire scientifically and avoid fire scientifically.
