A forest fire broke out in Dali, Yunnan, and nearly a thousand people are fighting it. Did the fire cause any casualties?

It was learned from the forest and grassland fire prevention headquarters in Dali City, Yunnan Province that a forest fire broke out in Dashaba Mountain, Wanqiao Village, Wanqiao Town, Dali City.

Forest Fire At about 9 am in Dali, Yunnan, a forest fire broke out in Xiaguan Town, Dali City. By 22: 00, the fire on the eastern line was basically controlled, and the northwest line was still spreading. At present, more than 1400 local people have put into fire fighting. The public security organs are still investigating the specific cause of the fire.

Our province is located in the south of China. Forest fires mostly occur in winter and spring, while most of them occur in spring and autumn in the north. During the forest fire prevention period, forest fires are prone to occur due to the decrease of rainfall and plant water content.

How to prevent forest fires every spring, in Panxi area, it is a high incidence area of mountain fires! This is mainly caused by the double superposition of climate and geographical location. Let's start with the climate. This area belongs to the subtropical dry-hot valley climate, and the four seasons are not obvious. But from last year 10 to May this year, the rainy season and dry season were obviously dry, and the climate was very dry. Coupled with the strong spring festival wind in the geographical position, this place is a mountainous area, and it is basically not blown at other times of the year, that is, hot air is blown in March and April, which is particularly heavy. It is dry and windy. Once a forest fire breaks out, it will be difficult to put it out! The danger is also great!

Combustible substances All organic substances in the forest, such as trees, shrubs, grass, moss, lichen, litter, humus and peat, are combustible. Followed by the dominant factor: the fire source. This includes natural fire sources, such as lightning strikes, volcanic eruptions and falling meteorites, and artificial fire sources, such as burning and smoking. Then there is fire weather, and forest fires often occur in dry seasons. At this time, the rainfall and water content in plants are less, and the ground is dry, which is prone to fire. A large number of facts show that forest fires can be prevented, combustible materials and fire sources can be controlled artificially, and fire weather can also be predicted and prevented.

The second reason is that a lot of weeds grow on the mountains in rainy months, which is related to abundant rainfall. In addition, due to closing hillsides to facilitate afforestation and urbanization in the past few decades, people's activities in the mountains are decreasing day by day, which further promotes the overgrowth of weeds. Coupled with months of dryness, once a fire breaks out, it will be difficult to put it out! This means that the fewer people live in the forest, the easier it is to catch fire, and the wind is strong, so it is difficult for the fire barrier to play its role!

At present, there is an intelligent monitoring and early warning system for forest fire prevention in the market, which is mainly composed of an intelligent monitoring system for fireworks identification, a communication system and an anti-theft system. To realize automatic forest video monitoring, accurate identification of fireworks, accurate location of fire points, deduction of fire spread trend, fire fighting command and decision-making, post-disaster assessment, etc. Through the intelligence and informatization of forest fire prevention, early detection, early reporting, early disposal, early fire fighting, early fighting, small fighting and early fighting can be realized.
