A forest fire broke out in Hejiang County, Luzhou City, Sichuan. Why are there frequent forest fires in Sichuan this year?
Forest fires occur frequently in the Sichuan and Chongqing regions, which is closely related to the continued high temperature and drought weather. High temperatures make combustibles more likely to burn. Continued drought further reduces the moisture content of combustibles, and the moisture content of the entire forest is also declining. The frequent occurrence of wildfires has made the local environment worse, and also made the hot weather even hotter due to the occurrence of wildfires.
A forest fire broke out in Hejiang County, Luzhou City. The local area rushed in rescue forces to put out the forest fire in a short time. For local people who may be affected, timely transfers were also carried out to ensure their safety. Mountain fires are prone to occur during high temperature and drought seasons. The hot weather in Sichuan and Chongqing this summer has also created opportunities for wild fires to occur frequently. Continuous high temperatures make forests dry and flammable
Although there are high temperatures and hot temperatures in summer, there is also abundant rain. The arrival of rain reduces the probability of forest fires. This summer, Sichuan and Chongqing suffered from extreme high temperature and drought weather. Such weather has caused the evaporation of water to continue to increase, and combustible materials lack water and become very easy to burn.
In the dry forest, under the high temperature for days, even a spark may be ignited. In addition, there are some light condensation situations in nature that cause the light source to converge at one point, raising the temperature at this point, and eventually triggering forest fires. The accumulation of combustibles makes forest fires imminent
As people begin to use clean energy and the ecological environment becomes better and better, there are more and more combustibles in the forest. Before that, there were people who went up the mountain to collect firewood to reduce the number of decaying branches and leaves in the forest.
In recent years, environmental protection awareness has increased, residents have begun to use natural gas, and the use of collecting firewood has become less and less. In such a situation, the forest is full of combustibles. Once there is high temperature and drought, these combustibles will There is a huge risk of spontaneous combustion.
Frequent wildfires will be alleviated by the arrival of rainfall. After the temperature drops, it will also be of great benefit to prevent wildfires from recurring.
