Do you think Xi'an belongs to north or northwest? (Dan Xuan)Zeropeople0%NorthwestZeropeople0%North China
Let us first look at the period of the Republic of China, the division of the geographical region, Xi'an is the northwest, or North?
From the point of view of natural geography, Xi'an is not in the Northwest region.
From the perspective of human geography, Xi'an is the northwest region? No Xi'an and Xi'an are located in the customs area of the Guanzhong Plain isMiddle and lower reaches of the Yellow River.
But speaking from the administrative point of view, Shaanxi is one of the five provinces in the northwest, northwest five provinces, specifically is northwest provinces Second District, because there are two provincial-level administrative units is ethnic autonomous region, northwest provinces area is in Shaanxi Province, Gansu Province, Qinghai Province, Ningxia Hui Autonomous Region and Xinjiang Uygur Autonomous Region.
Xi'an in the concept of becoming the northwest region, in fact, is a very late.
Guanzhong Plain was once the center of the Chinese Empire, why now become the edge of it?
Since the end of the Southern Song dynasty,The result of China's economic center moving eastward to the South, while China's economic center to the East and south migration has a large climate background. That is the Southern Song Dynasty, the overall trend of dry climate China.
(China's climate zone, the southern part of Shaanxi is a temperate monsoon climate).
East Asian continent, east of the East, the northwest inland depth and broad, tropical monsoon is difficult to deep inland. With the climate becomes drier, the subtropical monsoon more difficult to further inland, North China rainfall less and less, Shaanxi, Shanxi, Henan and Shandong, in before the Southern Song Dynasty is a major grain producing area in China, after the Southern Song Dynasty, let is located in the middle and lower reaches of the Yangtze River plain.
North China Plain is becoming more and more dry, there are natural reasons, there are man-made reasons, it should be said that the common role of nature and human, exacerbated by the drought in the North China plain. We take the Guanzhong Plain as an example to discuss the problem.
The middle reaches of the the Yellow River River in Guanzhong Plain in pre Qin, there are a large number of forest, historical records of the Wei River Valley"Mountain Kawatani Mi, Dumbledore day material".
In the Qin and Han Dynasties, the forest in the Guanzhong Plain continued to exist, but the coverage rate of the forest vegetation had reached the level of the Warring States period.
To the Tang and Song Dynasties, the Guanzhong Plain has no how much forest the, Zhongnanshan can use wood little, Qishan in the Song Dynasty turned into a tree Tu Shan.
Tang and Song Dynasties, the reduction of the Guanzhong Plain, the forest coverage rate, showing a roughly this trend, forest in plain area and river valley was one of the first cutting out and the focus of forest harvesting gradually shifted Qinling, Gansu Province and Luliang Mountain Alpine.
Anyway, in the Tang and Song Dynasties, Guanzhong plain green vegetation damage is very serious, and climate the overall trend of dry and cold, Guanzhong Plain become increasingly dry until lose its position as the major grain producing areas.
At the time of the Tang Dynasty, Guanzhong plain food has been unable to meet the needs of capital of Chang'an the Sui why excavation of the Grand Canal is to send the Jiangnan, Henan province grain to Luoyang, from Luoyang and then transported to Changan. Because from Changan to Luoyang is more and more high terrain, whether it is water or land, or land, transport are more difficult. So the Sui and Tang Dynasties are the two capital system, two in Beijing is Luoyang, West Changan, the positioning of Luoyang Dongdu is to the advantage of water transport.
To the Northern Song Dynasty, capital simply further eastward migration to more convenient of Kaifeng, the late Tang and Five Dynasties today's Kaifeng in Henan Province is water transport transfer station.
In simple terms, in ancient China, the central Shaanxi plain lost the political center, mainly because of the lack of food. Zhu Yuanzhang really wanted to put the capital in Xi'an, Xi'an has strategic advantage, from Henan to Guanzhong Plain, the terrain is more and more high, the Guanzhong Plain surrounded by the AI, typical easily defensible, can governing the country, back to a defense of self-defense. Zhu Yuanzhang specially make Prince Zhu to Xi'an investigation some kind of, Zhu Biao to Guanzhong Plain, found that this time of Guanzhong has not in the Han and Tang Dynasties period Guanzhong, decadent, it is difficult to here support capital of an empire. Zhu Yuanzhang also canceled the plan of capital in Xi'an.

However, with the development of modern land transport, Guanzhong Plain as China's geographic center, the role of the future should be more and more.
