Also as the northwest frontier, why is the population of Xinjiang much larger than that of Tibet?

Xinjiang and Tibet are both located at the western end of our country. The two autonomous regions are geographically close neighbors. There are mysterious Kanas, mysterious Tibetan Buddhist culture and many curious questions, big and small. For example, there is a huge difference in population between the two. One is that the land is vast and the population is sparse, and the other is that the two autonomous regions enjoy the same national family planning policy. Why is this difference caused? In fact, behind this problem, there are many factors such as geography and history.

We all know that Tibet belongs to the Qinghai-Tibet Plateau. The average altitude in Tibet is 4km, while that in Xinjiang is less than 1 km. The high altitude leads to a small population:

1, high altitude leads to fewer births.

High altitude leads to low fertility, which is what the hospital doctor told me when I was in the army. Anyone who returns to the inland areas from the plateau must take protective measures when sharing the same room. They can't have children for six months. In the meantime, even if you are pregnant, you must let the child go, otherwise there is a great chance that the child born will have problems. Because the plateau will cause problems to people's fertility, living at low altitude for more than half a year can only be restored.

Although people in Xizang has lived in a high altitude area for a long time and has adapted to the plateau environment, it still has a certain impact on fertility, resulting in a low fertility level for both men and women. Therefore, even if the state has policy encouragement, Tibetans will not have too many children.

2. High altitude leads to low population survival rate.

Anyone who has been to the plateau knows that there must be no symptoms of cold and fever in the plateau. Once you cough or have a fever, it may lead to emphysema. Without timely and effective treatment, it will lead to a very high mortality rate. This is true for adults, especially for newborn babies. The infant mortality rate in Tibet is much higher than that in inland areas. According to official statistics, the infant mortality rate has dropped from 430 in the early days of peaceful liberation. 20 18 decreased to 1 1.59? .

Because of the high altitude, many roads in Tibet often collapse and debris flow. These natural disasters not only caused property losses, but also caused casualties. Due to traffic problems, the injured can't get effective treatment, and the death rate will increase.

Second, influenced by historical factors, Xinjiang was once the land of the western regions. This is an important part of the Silk Road, attracting a large number of immigrants. There are soldiers sent by the imperial court, businessmen who come to do business, officials and criminals sent here, and all kinds of other people who are trying to survive here. A large number of people gathered naturally led to the birth of a large number of people. After generations of reproduction, these populations naturally formed a huge population.

Although Tibet also has the ancient tea-horse road, it has not attracted a large number of migrants to settle here. They are businessmen who come and go in a hurry. Without immigrants, the population can't get up.

Of course, there are other reasons besides these two reasons, but I think these two reasons are the main reasons that determine that the population of Xinjiang is much smaller than that of Tibet.
