In the Neolithic age, this ancient wasteland was developed by human beings in the three rivers and one river valley. The Qiang people in Gannan gradually established their own tribal alliance or attached to the Central Plains Dynasty.
In the Qin Dynasty, some places were under the jurisdiction of Lintao. In the Western Han Dynasty, Longxi County was in the East and Jincheng County in the north, with Baishi and Qiangdao counties.
In the Sui Dynasty, Lintao County, Luohan county and Dangchang county respectively controlled the northwest and southeast parts of Gannan.
In the early Tang Dynasty, the Prefecture was abandoned. Gannan was once the whole of Taozhou, Fangzhou and diezhou, and the parts of Hezhou and dangzhou. The northwest part of Gannan was within the scope of Tuyuhun and Tubo.

In the Ming Dynasty, it was under the jurisdiction of the capital of Shaanxi. In the Qianlong period of the Qing Dynasty, most of the Prefecture was under the jurisdiction of gongchang Prefecture, and Xiahe was under the jurisdiction of Fufan Hall of Xunhua.
In the second year of the Republic of China (1913), the government set up roads. Lintan county belongs to Lanshan Road, and Xigu county (now Zhouqu County) belongs to Weichuan road. In 1928, Xiahe County was established under the jurisdiction of Gansu Province. In 1937, Zhuoni set up a governing Bureau.
From September to December 1949, Lintan, Zhuoni, Xiahe and Xigu were liberated one after another.
In July 1952, Gannan Tibetan Area Committee was established.
In October 1953, Gannan Tibetan Autonomous Region was established.
On July 1, 1955, it was changed into Gannan Tibetan Autonomous Prefecture.
As of April 2018, Gannan Tibetan Autonomous Prefecture

Gannan Tibetan Autonomous Prefecture is connected with Aba Prefecture in Sichuan Province in the south, Huangnan Prefecture and Guoluo Prefecture in Qinghai Province in the southwest, and Longnan City, Dingxi City and Linxia Prefecture in the East and North. Its geographical coordinates are between 100 ° 46 ′ - 104 ° 44 ′ E and 33 ° 06 ′ - 36 ° 10 ′ n.
Gannan Tibetan Autonomous Prefecture is located in the northeast edge of the Qinghai Tibet Plateau, in the transition zone of Qinghai Tibet Plateau, Loess Plateau and Longnan mountain. The terrain of the plate is high in the northwest and low in the southeast. In the territory of overlapping mountains, ravines, complex terrain. The Jishi mountain system in the southwest, the West dipping mountain system in the northwest and the Minshan Dieshan mountain system in the South form the main framework of the state landscape. These high mountains meandering from west to East and the broad plateau between them constitute the main geomorphic areas with an average altitude of more than 3000 meters in the west, North and south of the state. In Zhouqu County, guazigoukou is the lowest point, 1172 meters above sea level, which is located in the east of the whole inclined terrain. Taking a comprehensive view of the topography of the whole Prefecture, there are three geomorphic areas, namely, the mountainous area, the canyon area and the mountainous and hilly area.
Gannan Tibetan Autonomous Prefecture belongs to the West Qinling fold belt, and its geological structure system mainly belongs to the East-West structure of Qinling. The tectonic belt is located in the central and southern part of the state, which formed early and lasted for a long time. It is the main skeleton structure of the state. After various tectonic movements, especially since Mesozoic era, the EW trending tectonic system of South Qinling has undergone strong changes. According to the analysis of stratigraphic sedimentation, the period of continuous sedimentation or basically continuous sedimentation starts from Sinian system and ends at Triassic system. The geological structure is characterized by shallow shelf facies deposition, occasionally volcanic rock deposition and magmatic intrusion. The inter-a-type subduction and compression at the end of Triassic led to the formation of Indosinian collisional orogenic belt and intense folding in zhoujing. In the Yanshanian period, due to the violent movement of the crust, the fault block tectonic stage was formed. In addition to the formation of Intermountain depressions and many fault basins, they also received continental fluvial and lacustrine deposits of Jurassic or Cretaceous. During this period, there was strong activity in the East-West structural belt, and the wudushan type structure was formed and developed on the basis of the East-West structure. The southern part of the state is located in the front arc of the West Wing of wudushan type, and a reflection arc is formed in Diebu. Qilu Helan Mountain type structural belt, which is located between Yinshan and Qinling East-West structural belts, was also formed during several tectonic movements in Mesozoic. The front arc of its west wing extends to the north of the state.
Gannan Tibetan Autonomous Prefecture has the characteristics of continental seasonal climate. The results showed that there were abundant light, low utilization rate, insufficient heat, large vertical difference, more precipitation and significant geographical distribution difference. Except for Zhouqu and Diebu, there is no severe cold period in some parts of the prefecture, the rest of the prefecture has long winter without summer and short spring and autumn. The annual average temperature in Gannan Tibetan Autonomous Prefecture ranges from 1 ℃ to 13 ℃. The general distribution trend is gradually decreasing from southeast to northwest. The distribution trend of temperature in four seasons is similar to that of annual average temperature, decreasing from southeast to northwest. The annual temperature range is generally between 20-22 ℃ and 23 ℃. Gannan Prefecture has the lowest annual temperature difference in the whole province, with the highest temperature in summer and the maximum value of monthly average temperature in July; the lowest temperature in winter and the minimum value in January. The geographical distribution of precipitation in the whole Prefecture is extremely uneven, and the precipitation varies greatly from place to place. The distribution trend is generally from Langmusi in the southwest to the surrounding areas. The seasonal precipitation distribution is also very uneven, with more warm season, less cold season and significant characteristics of hot and rainy season. The distribution trend of sunshine hours in the whole Prefecture gradually increases from southeast to northwest, with a range of 1800-2600 hours. The seasonal distribution of sunshine hours is uneven. Lintan, Hezuo, Luqu and Langmusi mostly appear in winter; Maqu, Xiahe and Diebu mostly appear in spring; Zhouqu and Zhuoni mostly appear in summer; the sunshine hours in autumn are the least.
