As of now, many forest fires have not been extinguished and tens of thousands have been forced to evacuate.

Various platforms are full of discussions on wild netizens on wild fire and high temperature. Among them, a problem on the American version of Zhihu has attracted the attention of journalists. "Why did China have rare wildfires?" Under this issue, netizens from various countries have raised many new questions. On the afternoon of the 18th, Ji Mu Journalist contacted Le Chengsheng, deputy director of the Forest Fire Office of the Hubei Forestry Bureau to interpret related issues.

Multi -country wildfires are raging

According to Agence France -Presse, wildfires in southwestern France have lasted for nearly a week. It is reported that since July 12, the over -fire area has reached 11,000 hectares. The French Ministry of the Internal Citizen said that multiple fire -extinguishing aircraft had sent firefighters to support firefighters.

According to BBC, as of now, about 16,000 people have been evacuated.

In addition, Spain and Portugal are under the shadow of wildfires. According to the Peninsula TV Station, about 3,000 firefighters and more than 60 aircraft fires have been dispatched. The report quoted Portuguese Broadcasting and Television that 12 firefighters and 17 civilians were suffering from minor injuries and needed treatment.

In Spain, firefighters are trying to extinguish more than 30 forest fires in Castilla, Leon, and Andalusia.

On the one hand, fight with wild fire, and continue to "suffer" at high temperatures.

According to the Asian News Station, the French Meteorological Department issued an announcement on the 17th that it is expected that from 16:00 on the day, 15 provinces across the country will be in a high -temperature red warning state, and 51 provinces are in a high -temperature orange warning state.

On the 16th, French member Melani posted on Twitter. She wrote: "Spain's soil surface temperature exceeds 59 degrees Celsius, and southern France is 48 degrees Celsius. This is not just summer, this is 'hell'. If we continue If you have nothing to do on climate, it will soon become 'end point of human life'. "

It has nothing to do with global warming

It is worth noting that a number of papers included in multiple foreign journals show that a considerable part of foreign scholars believe that in forest areas along the Mediterranean coast, summer wildfire is a natural phenomenon and it is difficult to avoid.

According to reports, especially Greece, Italy, Spain, Portugal, and France have been suffering from wild fire.

But in recent years, fire incidents have gradually upgraded. Last year, when the worst wildfire in the past decades was burned in Greece and Turkey, Reuters had quoted the EU atmospheric monitoring agency as saying that the Mediterranean region had become a "wild fire zone".

In this regard, foreign media generally believes that this is a global warming in "making trouble."

The BBC quoted climate experts in the report that climate warming can lead to more dry forests and more flammable trees. Moreover, global warming leads to hot and dry weather, which not only increases the risk of wildfires, but also creates "flammable" conditions for it.

According to the "Guardian" reported in June, some European countries are suffering from the worst drought for more than half a century. Residents in some areas in Italy are even required "unnecessary without water".

In addition, the BBC and "Daily Mail" also mentioned in the report that some biologists believe that wildfire is also related to vegetation. Like the mountain fire in Australia, in the eyes of experts, eucalyptus may be "culprit".

According to reports, Australia's eucalyptus accounts for more than 75%of the total forest area, and such trees are a "flammable material". The leaves are rich in fat and can easily cause forest fires.

"Moreover, when the bark is burning, it can be blown into the distance by the wind, causing a new fire," said Dr. Jane Kokusen at the University of Melbourne.

Management issues are also critical

In addition to climatic factors, management issues are also very important in the hearts of the majority of netizens.

On Quora, a netizen asked: "Why do wild fires happen frequently in the United States?"

A netizen from the United States replied: "Forest management is poor."

Foreign netizens answered questions on Quora

The reply from this netizen can't help but reminiscent of people in June this year, the US Forestry Administration acknowledged in a review report that its employees' calculation errors and judgment errors in the conventional "setting burning" operation caused the most serious record in New Mexico records since the record of records in New Mexico. Mountain fire.

It is reported that the US Forestry Administration originally wanted to "control the control" to incinerate shrubs and dead leaves to reduce the risk of forest fire in the dry season. Unexpectedly, the staff made a series of errors. For example, it is not enough to understand the drought in the southwest; the existing model is also "inaccurate"; the fire does not stop ignition after the fire becomes bigger.

Another example is the forest fire in Greece in 2018. According to the BBC report, at the time, the Greek Minister of Defense Tuscas said that "important signs" showed that the fire was caused by people.

In this regard, analysts pointed out that the reason for the reason is that the management is not effective.

Peninsula TV stated in the report that the deficiency of preventive measures and forest protection funds led to the failure to respond quickly to the incident.

Moreover, Europeans and Americans like to explore and like to camp in the wild, which also increases the risk of wildfire. In 2020, the wildfire in Oregon, the United States, was raging. Later, it was found out by the fire department that the Cocaharam and the Bald Peak Mountain Fire were caused by the camping of the people. Although in recent years, camping has also become a new fashion in China, under the leadership of China's cultural tourism department, many camps have been built in various places, providing suitable venues for people who like camping. Zhejiang Province even gave birth to a small program. Campers can clearly find the closest camping venue from home. Whether the camp can use information such as bright fire at a glance.

China has also attracted praise from foreign netizens in forest management. A foreign netizen on Quora left a message: "In China, no matter which mountain you climb, you can see the slogan forbidden smoking on the top of the mountain."

In addition, China has also used high -tech in forest management. On the afternoon of the 18th, Le Chengsheng, deputy director of the Forest Fire Department of the Hubei Forestry Bureau, mentioned in an interview with Jiyu Journalists that through the "smart fire prevention" system, the province's state -owned forest farms and forest nature reserves are under the eyelids of the satellite. Satellites will be comprehensively determined by temperature and smoke as soon as possible to show whether there is any strangeness, and the foreseeing officer will be quickly verified by drone or video surveillance.

According to Le Chengsheng, generally from September to May of the following year, it is a key fire prevention period. From May to August, it is a normal fire prevention period. The defeat leaves will also become combustible, so the province's forest guards and forest guards dare not relax and strengthen patrols.
