of culture and materials
the country's territory changed a lot. The country's territory was in an extending period before
and
the
An-Shi Armed Rebellion, and once extended to the Central Asia area.At the same time, the Tang
government founded the Ji-Mi-Fu-Zhou system in the Western Regions. The situation changed
rapidly when the An-Shi Armed Rebellion broke out. Then the central government mobilized the
troops in the Western Regions to participating in putting down the Rebellion, so the border defence
was weakened. Tu-bo took the chance to occupy a large amount of territory. Almost Long You Area
was oppupied by Tu-bo later in Tang Dynasty.
The thesis is divided into five chapters: political geography circumstance in northwest area in
early Tang Dynasty,including the situation of physical geography and the nation regime; the
political geography situation in the extending period of territory from Tai Zong to Gao Zong;the
political geography situation in the stable period of territory from Wu-zhou era to An-Shi Armed
Rebellion;the political geography situation in the shrinking period of territory after An-Shi Armed
Rebellion;relationship between the change of political geography situation and economy and
traffic.
Conclusion: From A.D. 7th to 9th century,Asia-Erope Continent was a place where Tang,
Da-shi and Tu-bo contended for political space. The country's power of politics, economy and
military strengthened before An-Shi Armed Rebellion, and part of the Central Asia area belonged to
Tang government. The territory reached to an unparalleled scale at that time, which can be divided
into three parts: the capital area where Chang-an and Luoyang were located in was the empire's
center of politics, culture and military; the Zheng-zhou that around the captals was where the finance
of central government stemmed from; the Ji-mi-fu-zhou system Tang government founded in the
frontier area was the military buffer zone with nation regimes in vicnity. At the same time, Tu-bo
appeared in the stage of history in A.D 7th century. After the King Song-zan-gan-bu unified the Tibet
plateau, Tu-bo's power strengthed rapidly and harassed Tang's frontiers inceasingly. The Tang
government put the defense police actively into effect so as to resist Tu-bo's aggression and defend
country's benefit in Long-you area. When An-Shi Armed Rebellion broke out, Tu-bo took the chance
to occupy vast territory of Tang Dynasty, like Minzhou, Lanzhou, Kuozhou, Guazhou, and so on.
Eventually, almost all Long-you areas belonging to Tang Dynasty was occupid by Tu-bo. In the field
of geopolitics, the national power strengthened in the earlier stage of Tang Dynasty and stronger than
Tu-bo. Tu-bo didn't have the strength contending with Tang Dynasty, even harassed the frontier once
a while. Until the An-Shi Armed Rebellion, the Tang government had no more advantage and the
national power was weakened.
