However, whether in the Western Zhou Dynasty or in the Spring and Autumn Period and the Warring States Period, the territory of the Central Plains Dynasty, especially the population, was mainly concentrated in the Yellow River Basin. Qin dynasty territory: about 3,546,900 square kilometers. In 22 1 year BC, Qin Shihuang established the Qin Dynasty on the basis of cutting off Qi Chu, Zhao Wei and Han. When calculating the territory area of the Qin Dynasty, apart from subtracting all or part of Xinjiang, * * *, Qinghai, Inner Mongolia, Heilongjiang, Jilin, Sichuan, Yunnan, Hainan, Taiwan Province Province and Gansu from 9.6 million square kilometers, it is about 608.6 1 square kilometer, plus one tenth of the territory of Vietnam.
Thus, the ruling area of the Qin Dynasty was: 9.6 million-6,086110,000+33,000 square kilometers = 3,546,900 square kilometers.
The territory of the Western Han Dynasty: about 6,663,700 square kilometers (it is also said to be/kloc-0,000 square kilometers). Although the territory of the early Western Han Dynasty was smaller than that of the Qin Dynasty, the areas of South Vietnam, East Vietnam and Hetao all decreased. But by the end of Emperor Wu of the Han Dynasty, the territory was twice that of the former Qin Dynasty, and the territory reached its peak. Except for today's * * and parts of Northeast China, its territory almost covers most of China's territory: four Korean counties, including Le Lang, are set up in the northeast, and three Koreans border on the middle of the Korean Peninsula.
Thus, the ruling area of the Western Han Dynasty is: 3,546,900+365,438+065,438+0,680 = 6,663,700 square kilometers.
Eastern Han Dynasty territory: about 6,546,200 square kilometers Western Jin Dynasty territory: about 6 15.5 million square kilometers Since the heyday of the Western Han Dynasty, although the territory control of the Central Plains Dynasty was affected by civil strife and other reasons, the total territory area was only slightly reduced.
Territory of Sui Dynasty: about 5 1 10000 square kilometers. In order to expand its ruling area, Yang Di continued to expand outward, eventually annexed Tuyuhun, but abandoned the Korean Peninsula. The territory of the Sui Dynasty was about 5 1 10000 square kilometers.
Territory of the Tang Dynasty: about1251.190,000 square kilometers. In the heyday of the Tang Dynasty, its territory reached the Sea of Japan in the east, the Caspian Sea in the northwest, the upper reaches of Lake Baikal and Yenisei River in the north, and Vietnam and Xisha Islands in the south, covering an area of about1000-160,000 square kilometers. After the mid-Tang Dynasty, the territory of Mobei and the Western Regions fell to the size of China at the end of the Tang Dynasty, but the Hetao area still existed.
