A sudden mountain fire broke out in Meixian County, Meizhou City, Guangdong Province. Usually, what causes such natural disasters?
One: Man-made fire sources Man-made fire sources are divided into productive fire sources and unproductive fire sources. Productive fire sources include land reclamation and miscellaneous burning, ash composting, mountain refining and afforestation, ridge burning, kiln burning, isolation belt burning, quarrying and blasting, and train throwing tiles. Non-productive fire sources include smoking in the wild, heating and cooking, burning incense and paper on graves, burning mountains to drive away animals, children or mentally retarded people playing with fire, intentional arson and so on. The fire source is the focus of our prevention of forest fires, because many times an inconspicuous move may bring a big fire. Once a fire breaks out, the most intuitive harm is to burn or burn trees and reduce the green area of the forest. And our fire officers and soldiers will also suffer personal injury when fighting in the forest. The best way is to prevent. We can prevent fire by predicting the general fire weather.
Secondly, the natural fire source is firstly dry season with little precipitation, secondly, the temperature is raised by the effect of wind-burning, and secondly, tree species, such as fir trees and pine trees, are very flammable, including pine cones and needles that fall to the ground. The ground vegetation and combustible materials under the forest rot after long-term accumulation, and then a large amount of combustible gas is produced, which is caused by sudden open flame combustion after mixing with rotten combustible materials; On steep slopes, ridges, rock ridges, saddles, single-mouth valleys, Caotanggou and other special and relatively closed landforms, the spreading forest fires make the combustible materials in these landforms preheat and burn together. Once there is a flame, the oil of trees is an excellent combustion-supporting material. It is easy to form a natural fire.
Third, the earth angrily punishes the balance conflict between human environmental protection and economy. Do you want to protect the environment or get rich? This is a realistic problem. Some industries have developed their economies on the basis of environmental protection. Man's desire to get rich and greed always remind him not to care about future generations. The money is earned, and the earth is gone? Where do you want your children and grandchildren to go? The earth is an ecological circulation system. If anything goes wrong, the final reaction is the result of a chain reaction. Everyone has personally experienced the disaster brought by novel coronavirus. I don't want it to happen again. Starting from everyone, our generation should shoulder the responsibility of repairing the earth. For our next generation, we can see penguins and polar bears. Maintain the ecological balance of the earth, reduce air pollution and prevent global warming.
The harmonious development between man and land is very important. Nature is a kind mother and a cruel butcher. ? Everything depends on how we get along with it.
