Four Plateaus Four Great Basins, Why is there a lack of "Four Plains"?The mysteries of the terrain are revealed
China's landforms are diverse, ranging from plateaus and hills to basins and plains. People are familiar with the "Four Great Plateaus" and "Four Great Basins", but they do not know much about the "Four Great Plains". How so?
First of all, we need to know what the prairie is. A flat area is an area with flat ground and little undulation, generally less than 200 meters, and the area is vast. Compared to plateaus, hills, and basins, grasslands have smaller heights and flatter terrain, and generally have larger areas.
Therefore, why do not there be "four plains" in our country?In fact, it is not that our country does not have large flat land, but there are large pieces of land in small plots of land all over the country, on large plots of land. China has several large plains such as the Northeast Plain, the North China Plain, and the Middle Reaches of the Yangtze River Plain. All three areas of land are more than 200,000 square kilometers, but all are less than 200 meters, so they are often referred to as the "three plains".
The northeast is the largest plain in China, with a total area of 350,000 square kilometers. The land here is vast and fertile, and it is the most important commercial grain base in the country.
North China is the northern region of China, with a total land area of 300,000 square kilometers. The terrain is flat, and it is a major industrial and agricultural production base.
The middle reaches of the Yangtze River are a large plain in southern China, with a total land area of 200,000 square kilometers. With flat terrain and numerous rivers, it is a major agricultural and animal husbandry production base.
In addition, in China, there are also small plains such as the Guanzhong Plain, the Hetao Plain, the Chengdu Plain, and the Pearl River Delta Plain. Although they are small in scope, they all have their own geographical characteristics and significance.
The Pearl River Delta is an important area on the South China coast of China, and it is the alluvial mass of the three main branches of the Pearl River, the Xijiang, Beijiang and Dongjiang rivers, with a total area of 11,000 square kilometers. Although its land area is not large, it has become a major development area in South China, and its production and service industries are very developed.
The Guanzhong Prairie is a large plain in northwestern China, with a total land area of 44,900 square kilometers. With its gentle terrain and abundant produce, it was a major transportation hub on the ancient Silk Road, as well as a major agricultural and production center.
The Hetao Plain in Inner Mongolia, covering an area of 25,000 square kilometers, is a typical ecologically fragile zone. With gentle terrain and pleasant weather, it is an important agricultural and animal husbandry production base in Inner Mongolia.
Chengdu is a large plain in southwest China, with a total area of 1With 881,000 square kilometers, it is a vast land. As an important agricultural and animal husbandry production base in Sichuan Province, its geographical location is superior and the climate is suitable.
In short, in China, although the area of the plains is large, the spatial differences are very large, and the area is also very small, so there is no such thing as the so-called "four plains". In contrast, the concept of the "Three Plains" is more universal and more realistic.
