since the blogger's video became popular, many "curious" tourists have chosen to come to this mysterious "niche" area during the national day holiday to find out. as a result, too many people poured into ailao mountain, and the originally sparsely populated "forbidden zone" turned into an overcrowded "scenic spot."

on october 5th, topics such as #爱拉山 traffic jam# #爱拉山有狠地的 magnetic field# and other topics were on the hot search list, attracting the attention of netizens.

on the 5th, the official account once again released an aerial video of the mountain drive on ailao mountain, and asked, "how many 'armies' are still on the way to ailao mountain during the national day holiday?" the video showed that on the way up the mountain, they were all cars, and they were so blocked that they couldn't move.

some netizens said, "i really didn't expect it to be: everyone, everyone, everyone in ailao mountain, everyone, everyone." "now it's really 'the wind that misses you has blown to ailao mountain.'"

although ailao mountain is jokingly called the real-life "yunnan worm valley" on social media, in fact some areas here have been developed into scenic spots, with relatively complete supporting facilities and services, and many tourists come here to visit. . as long as you don't enter undeveloped virgin forest areas, you will encounter almost no risks.

it is reported that many outdoor enthusiasts hike on the outside of ailao mountain, but in the depths of ailao mountain, even local villagers do not dare to go there rashly.

on october 5th, @云南伊拉山天堂 issued a safety reminder: the depths of ailao mountain are dangerous, do not rush to unknown areas, and do not go deep into undeveloped areas.

how dangerous is ailao mountain?

why is it a restricted area?

to the outside world, ailao mountain is not as famous as its neighboring wuliang mountain. in fact, ailao mountain and wuliang mountain are not only adjacent to each other, but also connected in parts of the northern part.

at the beginning of 2021, at the fourth session of the 13th yunnan provincial people's congress, deputies put forward the "recommendations on accelerating the construction of ailao mountain-wuliangshan national park in yunnan province." the yunnan provincial forestry and grassland bureau introduced the basic situation in its reply on may 25: the ailao mountain-wuliangshan area is located in the central part of yunnan province. it is located at the junction of three major geographical areas: the yunnan-guizhou plateau, the hengduan mountains and the southern edge of the qinghai-tibet plateau. the wuliangshan ecological barrier in the ailao mountains in the basic pattern of "three screens and two belts" of the provincial ecological protection red line has an area of ​​8575.58 square kilometers included in the ecological protection red line. it is an important part of the ecological security barrier in the southwest; it is the transition from the tropical to temperate zones of the asian continent. an important corridor for species migration and gene exchange, it is one of the areas with the largest preserved area of ​​subtropical evergreen broad-leaved forest in my country. it is also the main habitat of the national first-level protected animals, the western black-crested gibbon and the indo-chinese gray langur, and the national the species diversity patterns and causes of the important distribution areas of first-level protected plants such as yunnan yew, cycad cycad, ginkgo biloba, and magnolia longifolia have been highly concerned by scholars at home and abroad.

specific to the ailao mountain national nature reserve, on both sides of the north-south direction, there are two management branches of zhenyuan and jingdong in pu'er city on the west slope, and on the east slope there are two management branches of shuangbai and chuxiong in chuxiong prefecture and yuxi. xinping municipal administration bureau, and the nanhua administration bureau of chuxiong prefecture to the northwest. the total area of ​​the region is 67,700 square kilometers. the highest peak is 3,166 meters above sea level, and the average altitude is 2,000 meters.

how dangerous is ailao mountain? why is it a restricted area?

it is understood that some areas of ailao mountain have been developed into scenic spots, but there are still many dangers deep in the mountains and forests.

wang yu, a senior geological survey expert in yunnan, said that the ailao mountains are the product of the collision and subduction of the indian plate to the eurasian plate. they are symbiotic with the red river deep fault and have strong neotectonic movements. under the combined action of internal and external forces, fault structures developed, mountains rose to a large extent, and rivers cut sharply down, forming a deeply cut high-to-high mountain landform. "this means that ailao mountain has high and steep slopes, and the terrain changes drastically, making it difficult to travel."

due to the large relative height difference of ailao mountain and the obvious vertical distribution of climate, there are six climate modes from the top to the foothills, including south subtropical, middle subtropical, north subtropical, warm temperate zone, temperate zone and cold temperate zone climate. wang yu said, “the climate is complex and it is easy to encounter sudden changes in weather.”

ailao mountain is an area with the most complete preservation of biodiversity and plant communities of the same type at the same latitude in the world. there are many wild animals here, including bengal tigers, green peacocks, black gibbons, clouded leopards and other national first-level protected animals, as well as more than a thousand species of higher plants, including the "living plant fossil" thoreau tree, and the forest canopy density is extremely high. wang yu said, "once people enter a dense forest, it is easy to lose their way and encounter poisonous snakes, leeches, wild beasts, etc."

in addition, the primeval forest of ailao mountain is very foggy, has no roads, and has no communication signals. in the dense fog and sealed environment, a large amount of carbon dioxide will be released at night. if you walk for a long time, you may lose consciousness due to lack of oxygen. in addition, ailao mountain has been measured to have anomalies in the strength of the earth's magnetic field, causing the compass to malfunction and increasing the risk of getting lost.

there have been many cases of missing persons and deaths

in 2021, the loss of contact and death of four professional geological survey personnel has cast a layer of sadness on ailao mountain.

among the four people, the oldest is 32 years old and the youngest is 25 years old. the kunming natural resources comprehensive survey center of the china geological survey where they work is an elite geological survey team. previously, they all served in the golden force of the armed police.

when setting off, the four people carried a compass, an engineering shovel, a shovel, a disposable raincoat, a day and a half of dry food, a mineral water bottle, gasoline and other items. gasoline was specially poured by drivers from spare oil drums for them to carry. it could be used to make fires in the wild for warmth, to protect against wild beasts, and to dilute paint. in addition, each person also carries an rtk device. rtk is a field measurement method with centimeter-level accuracy. when the rtk button is turned on, the real-time position of the team members can be locked based on the data returned by the satellite system.

however, such a professional and well-equipped team lost contact and died in ailao mountain.

hu wenkun, president of the yunnan mountaineering outdoor sports association who went to the rescue, said, "when our command headquarters measured the magnetic field at the place, we found that the magnetic field at the rescue site was twice as strong as the magnetic field in heizhugou, sichuan." hu wenkun believed that the loss of contact was suspected. it was mainly due to the interference of the local magnetic field that caused them to get lost. the victims themselves did not realize the danger, and the hypothermia accident occurred.

tang xiaochun, a professor and doctoral supervisor at the school of geography and tourism of guangdong university of finance and economics, said that geomagnetic anomalies do exist in some places. this is mainly caused by strata or rocks with magnetic minerals exposed in this area, which is a relatively common situation.

hu wenkun reminded that people without field experience should never enter undeveloped mountainous areas, “because there are too many dangerous factors in these places, such as wild beasts, sudden weather changes, complex terrain, etc. the main cause of casualties in such mountains and forests.”

however, this is not the first tragedy in ailao mountain where people lost contact and died.

professor han lianxian, who has more than 40 years of experience in field survival surveys and teaches ornithology and field survival at southwest forestry university, recalled that more than 20 years ago, several teachers and students from the art department of simao normal college (the predecessor of pu'er college) went to ailao mountain to sketch. one of the students went over the mountain to see the monkeys in chuxiong. he got lost on the way back and did not return that night. the local government began to organize a search and rescue. the search and rescue failed the next day. when he was found on the third day, the student was lying in a ravine. by the pond, he had lost his vital signs and there were no traces on his body.

han lianxian remembered that in the past missing contacts in ailao mountain, a foreigner was lucky enough to survive. just next door to where the four geologists lost contact this time, in xujiaba, jingdong county, the hinterland of the ailao mountains where the chinese academy of sciences positioning station is located, a foreigner lost his way while going bird watching and did not return that night. it was december, and the temperature was lower than when the four investigation team members lost contact this time. at that time, the staff of the chinese academy of sciences positioning station were anxious, but with rich experience, they knew that search and rescue could not be done at night. they sent people to search and report the news layer by layer the next day. as a result, they found the missing foreigner during the search. successful rescue. han lianxian said that this was because the foreigner also had experience in surviving in the wild. on the night he lost contact, he used a swiss army knife to cut many branches, stacked them in a sheltered place and climbed in to avoid the cold to avoid hypothermia. the second climb to the top of the mountain every day at dawn. "the higher you stand, the easier it is to be discovered by the outside world."
