3D restoration of mountain fires in Chongqing: more than 7 days 10 mountain fires. Why are mountain fires so frequent?

Mountain fires occur frequently in Chongqing, with more than 10 in 7 days. Even if the mountain fire is put out, it is easy to rekindle because of the continuous high temperature and dry weather. The frequent occurrence of mountain fires in Chongqing this summer has a lot to do with the continuous high temperature and dry weather. High temperature intensifies the increase of forest moisture, making combustible dry, and continuous high temperature provides the necessary temperature for combustible combustion.

Forest fire prevention is very important. After entering the forest, we often see such slogans. Everyone is responsible for forest fire prevention? . This summer, many places in the country suffered from unprecedented high temperature and dry weather, which will last longer and will also cause disasters. The frequent occurrence of mountain fires in Chongqing is caused by this climate, which has the following two necessary conditions.

First, continuous high temperature brings drought, which makes combustible materials easy to burn and causes natural fires. Usually two conditions are required. The first point is that there are many dry combustibles in the forest; The second point is that the temperature continues to rise, creating conditions for the combustion of combustible materials.

Since Chongqing entered the dog days, the continuous high temperature and lack of rain not only aggravated the evaporation of water, but also made many combustible materials in the forest burn easily. Under such circumstances, even if there is only one Mars, combustible materials may be ignited, which may lead to mountain fires.

Second, the forest vegetation is lush and the local environment is getting better and better. High temperature and dry weather make the forest very dry. At present, the forest is full of a lot of combustible materials. This situation exists in mountains and forests all over the country. With the continuous development and progress of society, people's dependence on firewood is decreasing. Coupled with the protection of the natural environment, the forest coverage rate has been continuously improved.

Before natural gas was widely used, firewood was still an essential raw material for daily fire and cooking. With the popularity of natural gas, fewer and fewer people use firewood. Under such circumstances, combustible materials slowly accumulate in the mountains, creating favorable conditions for the outbreak of mountain fires.

High temperature and dry climate can easily lead to frequent mountain fires. If you want to avoid mountain fires, all you need is a thorough rain. With the arrival of rain, the forest will become wet, combustible materials will be reduced, and its flammability will be reduced.
