Geographical problem: why not move a large number of people to the northwest to develop the economy?

1. When migrating population to the west, we should consider the environmental carrying capacity of the west. Relatively speaking, the environment in western China is relatively fragile. Although the west is rich in resources, the natural conditions are not superior, with less precipitation, sandstorms, cold waves, poor soil and few rivers, and most parts of the west are short of water resources. 2. Actually, the so-called western region is a relative concept. Only in terms of the number of people, the western region is less than the eastern region, but this is inseparable from the regional industrial structure. To put it simply, for example, in western pastoral areas, 0. 1 square kilometer can provide the necessary feed for one sheep at most, and at least 20 sheep can feed one person, which means that the carrying capacity of 2 square kilometers is one person. But the carrying capacity of the East is far greater than this figure. From this perspective, the population density in the west is not too small, but too large. Of course, these can be gradually improved through the adjustment of industrial structure, which takes time and cannot be solved by immigration alone. In the past, this method was to treat the symptoms rather than the root cause, and the population flow was from economically backward areas to economically developed areas. The fundamental reason for the small population is the difference in the level of economic development. Only by taking measures to develop the western region can the population distribution be balanced. If the economy is underdeveloped, it is not only difficult to take measures to move the population westward, but also unable to solve the fundamental problem. In fact, the population of the western region has been increasing, and its proportion in the national population is also increasing (except Sichuan). Of course, the proportion in the east is also increasing, while the provinces with declining population proportion, that is, the provinces with net emigration, are concentrated in the middle, such as Henan, Hunan, Jiangxi, Anhui and other provinces, while the west only includes Sichuan. The reason is very simple, with a large population and a small number of people, it is natural to go out to make a living.

Sorry, I'm not a teacher. I can only collect and answer these questions. I hope it will help you.
