There were 9 mountain fires in Chongqing in a week. Are they caused by man-made or spontaneous combustion?

There were 9 mountain fires in Chongqing in a week. Frequent mountain fires are not man-made, but masterpieces of nature. It will frequently cause mountain fires, which has a lot to do with the long-term high temperature and dry weather in Chongqing. The high temperature and dry weather makes the combustible materials in the mountain forest increase, and the existing combustible materials become dry and easy to burn. Under the action of high temperature, these combustibles are ignited, which eventually leads to mountain fires.

Among many mountain fires, Beibei mountain fire burns the most violently, and rescuers participate the most. Fortunately, through hard and unremitting efforts, the mountain fire was finally successfully extinguished, which prevented the mountain fire from continuing to burn. Frequent mountain fires originate from spontaneous combustion, and the following two factors are necessary conditions for mountain fires.

1. High temperature and dry weather Summer was originally a time when mountain fires were not easy to occur. At this stage, the mountains are lush and rainy, and the land on the mountains is wet. Under such circumstances, it is difficult to ignite the wet forest even in hot weather.

The continuous high temperature and lack of rain in Chongqing this summer made the climate extremely dry. In this case, the mountain forest becomes dry, the evaporation of water in leaves intensifies, and many combustible materials become more and more easy to burn because of the loss of water.

In the drought, the original litter in the mountain forest became dry, and some light green plants also died in the drought. In this way, the accumulation of combustible materials on the mountain created the necessary conditions for the outbreak of mountain fires.

Second, the existence of low ignition point combustible materials In order to make the mountain fire spontaneously ignite, not only combustible materials are needed, but also the temperature needs to reach the ignition point to ignite the combustible materials. According to common sense, the combustion temperature of combustible materials exceeds several hundred degrees Celsius, and even if it is heated again in summer, it is not easy to ignite these combustible materials. However, nature is so magical, and there are some in the mountains? Arsonist? It was they who lit the mountain fire.

Peat soil is easy to heat up under high temperature irradiation, which will ignite rotten leaves and lead to mountain fires. In addition, there are low-burning white phosphate rock, as well as flammable plants such as rock rose and white fresh.

Therefore, the frequent mountain fires in Chongqing are caused by spontaneous combustion, not artificial arson. If it is arson, it will be severely punished by law and bear the losses caused by it.
