A forest fire broke out in Yanqing, Beijing. What is the cause of this forest fire?

I believe you have recently discovered that there have been frequent fires in forest areas all over the country in recent days. On March 18, a fire broke out in yongningzhen Forest, Yan 'an District, Beijing, and then firefighters quickly arrived to put out the fire. So what are the causes of frequent fires in various regions today?

First, the fire caused by human factors

1. Farmers burn straw. Some farmers' land is just near the forest, and it is easy to cause fires no matter how strong the wind is.

2. Burning paper when going to the grave, Tomb-Sweeping Day and some festivals, the custom of going to the grave has continued from the older generation to the present. Although the state now stipulates that it is forbidden to go to graves to prevent fires from damaging the environment, there are still many people who are disobedient and still go to graves. Generally, the cemetery will be chosen on the mountain, surrounded by all kinds of trees, which is easy to cause fire.

3, illegal hunting, although the country has long banned hunting, but there are still many people for their own interests do not comply with the regulations, and hunting with guns in forests and mountainous areas is a very dangerous thing, if the weather is very dry, encounter some flammable materials, it is easy to cause a fire.

4, picnic, many people choose to enter the forest in order to experience the feeling of nature, and in the process of picnic, it is necessary to heat food with open fire, which is easy to lead to fire, and sometimes it will lead to resurgence if you don't pay attention to the fire, which will eventually lead to great disaster.

Second, the natural environment.

Fires are most likely to occur in spring and autumn, because the weather in these two seasons will be very dry and the wind is still relatively strong, so once a fire breaks out, it will be difficult to control. In the forest, there are trees and some dead branches and leaves everywhere. If the light is too strong during the day, it will easily lead to overheating of combustible materials and fire. And the wind is still relatively strong in spring. After the fire breaks out, the fire will use the wind, and the wind will help the fire, which will spread rapidly, and it is easy to cause the fire to continue to camp, thus forming a large-scale fire, so once a fire breaks out, the consequences will be very serious.
