Development history
The predecessor of Tangjiahe National Nature Reserve is the former Qingchuan logging factory of Mianyang special area and the forest management office of Qingchuan county. In 1978, it was established on the basis of demolishing the original logging factory in Mianyang special area and the forest management office in Qingchuan County, which was reported by Sichuan Provincial Revolutionary Committee and approved by the State Council with the document of GF (1978) No. 256. Due to the rich biodiversity in the area, in order to facilitate the protection and management, the provincial government allocated 1.1 million yuan from 1985 to 1986. Through the efforts of governments at all levels, 301 people from 65 households of Qianshao village in the area were moved out of the reserve, which controlled the interference of human activities and created a good environment for the reproduction and survival of rare wild animals and plants such as giant pandas. in July 1986, the State Council approved the promotion to a national nature reserve with a total area of 410900 mu. in December 1991, with the approval of the people's Government of Sichuan Province, Tangjiahe National Nature Reserve was jointly managed by the original province and county, and the provincial management system was changed to the direct management of the Forestry Department of Sichuan Province. The forestry bureaus of Guangyuan City and Qingchuan County assisted in the protection and management work. The management organization was changed from the original "Tangjiahe National Nature Reserve Management Office of Qingchuan county" to "Tangjiahe National Nature Reserve Management Office of Sichuan Province" The "National Nature Reserve Management Office" is a vice county level institution directly under the Forestry Department of Sichuan Province.

geology
Tangjiahe scenic spot is located in the wave strike area of Longmenshan fault zone and North Qinling and Motianling fold zones in Qinghai Tibet Autonomous Region, with ancient strata exposed. The exposed strata are mainly slate, granite, limestone and sandstone. The rock in the reserve is the end of the glacier, and the end moraine Bank of the glacier can be seen. Passing through caijiaba, baixiongguan, xiaowanhe, maoxiangba and shuichiping, you can see the distribution of granite boulders transported from different places by glaciers on the whole line. In these areas, we can also see evidence of various glacial activities, such as the unique U-shaped Valley landform of glaciers, the iceberg landform, the suspended Valley, the ice mortar and the large boulders; the yangjishi, the dengzhanshi and the glacier scratch formed during the glacier migration. It is high in the northwest and low in the southeast, with the highest altitude of 3864m and the lowest altitude of 1150M.
