The first is the lack of water resources. Since ancient times, people have known that water is the source of life, and everything can survive without water. However, the water resources in no man's land in northern Tibet in Hoh Xil are quite scarce. Although there are many lakes in this place, the water in these lakes is saline-alkali water, which can not be used for production and life at all. Due to the lack of water resources, although his grassland is vast, the growing period of Qing Dynasty is very short, and more places are the vast Gobi. In the movie "Hoh Xil", its landform has been fully displayed, and there are often scenes of animals running wildly. It is really spectacular from a distance, but it also fully shows the desolation of this land.
The second is that the oxygen content in the air is very low. Living in this environment is likely to lead to hypoxia, causing drowsiness, distraction, memory loss and other symptoms, followed by confusion, convulsions, drowsiness or coma, and even death. In particular, the human heart is the organ with the largest oxygen consumption and the highest metabolic rate, and hypoxia is the most likely to cause damage to it. Severe hypoxia and persistent hypoxia can reduce myocardial contractility, slow heart rate, reduce cardiac blood volume, form a vicious circle with hypoxia symptoms, and even degeneration and necrosis of myocardial cells, leading to heart failure. Oxygen is important not only to human beings, but also to animals. In such a big environment, the requirements for animals' own conditions are extremely high, but it is difficult for anyone with poor physical fitness to survive here.
The third is that the temperature in Hoh Xil is low, which is not conducive to survival. The average temperature in Hoh Xil is about-10.0℃ ~ 4. 1℃, and the lowest temperature is -46.2℃. In fact, in winter in the northeast, the temperature will not drop so low. In the north, it's already heated. Even before heating, everyone can burn charcoal to keep warm. But Coco doesn't have this condition in his heart, so he can only endure it. Moreover, in such a low temperature environment, the growth rate of plants is very slow, and plants are the energy source in the biological chain. Low temperature and insufficient food make it more difficult to survive.
Fourth, there are many beasts in Hoh Xil, and it is difficult for human beings to coexist with them. Because Hoh Xil has a very complete ecosystem, all kinds of wild animals are struggling out in a harsh environment. They are natural fighters. It is difficult for human beings to like this area, let alone coexist with it.
In recent years, this area has attracted more and more attention, and everyone tries their best to make it more livable. No man's land in Hoh Xil is terrible for eating people, and the mountains and rivers are magnificent. In the near future, this place can also become a livable place.
