It is located on the south side of the Motian Ridge on the northwest side of Longmen Mountain. The entire terrain tilts slightly from the northwest to the southeast. The terrain is complex, with overlapping peaks and severe cuts. The Motian Ridge on the northern edge is as high as 3,000 meters above sea level. , to the northwest corner of the Great Lawn area, the altitude is 3837 meters, and the valley is generally 150 meters above sea level.</span><span style="color: rgb(0, 0, 0);">0 or less.

During the Quaternary glacial activities, no large-area ice caps were formed, so many ancient species have been preserved. According to a survey, there are more than 3,100 species of higher plants in the area, and more than a dozen precious tree species include involucrata, aquamarine, Liriodendron tulipifera, golden maple, and Eucommia ulmoides. Vegetation has a typical vertical distribution. There are 310 species of vertebrates, among which the national key protected wild animals include giant pandas [2], golden monkeys, takin,</span><a href="https://baike.baidu.com/item/%E7%BB%BF%E5%B0%BE%E8%99%B9%E9%9B%89/350755?fromModule=lemma_inlink" rel="noopener noreferrer" target="_blank" style="color: rgb(0, 0, 0);">Green-tailed Pheasant</a><span style="color: rgb(0, 0, 0);">, blue-eared pheasant,</span><a href="https://baike.baidu.com/item/%E7%BA%A2%E8%85%B9%E9%94%A6%E9%B8%A1/351840?fromModule=lemma_inlink" rel="noopener noreferrer" target="_blank" style="color: rgb(0, 0, 0);">golden pheasant</a><span style="color: rgb(0, 0, 0);">There are 25 kinds of them, which are extremely rare.

These areas are rich in arrow bamboo resources. The bamboos that bloomed and died in the 1970s have been regenerated and grown to more than 1 meter high. They provide abundant food and a good living environment for rare animals such as giant pandas, allowing the giant pandas in the reserve to live a good life. The establishment of the reserve The Baixiongping Ecological Observation Station, the second famous domestic and foreign giant panda field positioning and observation station, is located here.</span></p><p> <span style="color: rgb(0, 0, 0);">At the same time, the area is also an important transit point for migratory birds migrating from the temperate zone to the tropics, which is also rare in our country. Therefore, Tangjiahe Nature Reserve has important protection, scientific research, education and ecological value.</span></p><p> <span style="color: rgb(0, 0, 0);">Tangjiahe National Nature Reserve is located in the high mountains and deep valleys of the Minshan Mountains on the edge of the southwest basin. There are mountainous areas in the area.</span><a href="https://baike.baidu.com/item/%E5%B8%B8%E7%BB%BF%E9%98%94%E5%8F%B6%E6%9E%97/2292720?fromModule=lemma_inlink" rel="noopener noreferrer" target="_blank" style="color: rgb(0, 0, 0);">evergreen broadleaf forest</a><span style="color: rgb(0, 0, 0);">, Evergreen broad-leaf and deciduous broad-leaf mixed forest,</span><a href="https://baike.baidu.com/item/%E9%92%88%E9%98%94%E5%8F%B6%E6%B7%B7%E4%BA%A4%E6%9E%97/2183138?fromModule=lemma_inlink" rel="noopener noreferrer" target="_blank" style="color: rgb(0, 0, 0);">Coniferous and broad-leaved mixed forest</a><span style="color: rgb(0, 0, 0);">,</span><a href="https://baike.baidu.com/item/%E4%BA%9A%E9%AB%98%E5%B1%B1%E9%92%88%E5%8F%B6%E6%9E%97/2422343?fromModule=lemma_inlink" rel="noopener noreferrer" target="_blank" style="color: rgb(0, 0, 0);">subalpine coniferous forest</a><span style="color: rgb(0, 0, 0);">, alpine shrubs and meadows and other five types of spectrum.

Flowering plants begin to appear in mid-March, and frost stops in low-altitude river valleys at the end of April. From April to May, grass and wood plants grow rapidly, and wildebeest go down to the river valleys to feed, or gather in groups in the forest. Golden monkeys descend to birch forest areas to feed on young buds. From June to July, flowers bloom in the river valley, bees and butterflies fly, wildebeest return to virgin forests and alpine meadows, and golden monkeys move to high-altitude coniferous forests. In August, black bears move down to river valleys to feed on fruits. Autumn arrives in September, the leaves turn red, and after January, the autumn colors are extremely intense. In mid-October, the leaves fall and snow falls in the mountains. In mid-December, heavy snow falls and black bears enter hibernation. However, giant pandas wander around the hillsides throughout the winter to feed on frozen arrow bamboo.</span></p><p> <span style="color: rgb(51, 51, 51);">Tangjiahe National Nature Reserve is rich in cultural landscapes and has many pass fortresses, which are easy to defend but difficult to attack. It has been a battleground for military strategists of all ages. During the Three Kingdoms period, this was the place where the Shu Kingdom garrisoned troops and fortified its troops. Wei general Deng Ai "wrapped himself in felt and descended" to destroy all the places Shu passed through. During the Ming Dynasty, Ming general Fu Youde followed Deng Ai's example and destroyed Xia in this way. There are many historical sites and legends on the Yinping Ancient Road, including Motian Ridge, Beixiong Pass, Kongming Monument, Writing Cliff, Whetstone, Tiger Pan Stone, Luoyigou, Luoyi Bridge, Red Army Bridge and many other historic sites.</span></p>
