Overview of the concept of regional concept Sichuan area is a regional geographical concept, which refers to the geographical area dominated by Sichuan Basin and its adjacent areas, including Sichuan Province. From the perspective of topographic units, Sichuan in a broad sense generally includes Sichuan Basin, Western Sichuan Plateau, Hanzhong Basin, Three Gorges of the Yangtze River and parts of northern Yunnan-Guizhou Plateau.
Sichuan Basin Sichuan Basin is also called Red Basin, Purple Basin and Envelope Basin. Sichuan Basin is located in the middle of the eastern edge of China, surrounded by connected mountains, including the central and eastern Sichuan Province and most parts of Chongqing. It is the main body of Sichuan and Chongqing, with dense population, dense towns, prosperous economy and culture, pleasant climate, beautiful mountains and rivers, outstanding people, rich resources and superior location.
Sichuan basin is the home of the vast majority of Sichuan population. It is one of the most densely populated areas in China and even the world, and it is also the cradle of Shu culture. Known as the "land of abundance". Zhuge Liang, the prime minister of Shu, once praised it as "fertile soil in Wan Li". China is a famous red bed basin with the most typical shape, the southernmost latitude and the lowest elevation in the great basin of China. It is located in the upper reaches of the Yangtze River, which connects the East China Sea of China. It is the largest outflow basin in China.
Western Sichuan Plateau The western Sichuan Plateau belongs to the high altitude area bordering Qinghai-Tibet in the west of Sichuan Province, and is called "Western Sichuan Plateau". It is actually an extension of the southeast of the Qinghai-Tibet Plateau. On this land, peaks such as Queer Mountain, Daxueshan Mountain and Qionglai Mountain fluctuate continuously, and rivers such as Jinsha River, Yalong River and Dadu River flow through it, forming a spectacle with high mountains and deep valleys. Dianda Village, where Gelai Caiwen is located, is located in the Tongtian River Valley in the upper reaches of Jinsha River.
The total area of western Sichuan Plateau is 236,000 square kilometers, of which alpine grassland accounts for more than half. The grassland here is rich in species and can be called the best pasture in the whole Qinghai-Tibet Plateau. On the western Sichuan Plateau, there are three kinds of herders. From Shiqu and Dege to Songpan and Zoige in the north, the terrain is relatively open and the climate is cold. The herdsmen there only graze and don't farm, and their daily life is similar to that in the Sanjiangyuan area of Qinghai. Most of the central and southern parts are also alpine grasslands, and the climate is slightly warmer than that in the north. Herdsmen reclaim some cultivated land near the grassland in winter and grow some forage and food for their own use, but they still mainly graze.
Hanzhong Basin Hanzhong Basin, also known as Hanzhong Plain, is located in the south of Shaanxi Province, in the upper reaches of the Han River, between Mianxian and Yangxian, and between Qinling and Dabashan. It is a faulted basin, a land of plenty and a house of national treasures. Hanzhong is the birthplace of the Han Dynasty, so the local slogan is "the birthplace of the Han family, the cornucopia of China". This couplet is cleverly embedded with the word "Hanzhong Basin".
Yunnan-Guizhou Plateau Yunnan-Guizhou Plateau, located in the southwest of China, is one of the four plateaus in China, starting from Hengduan Mountain and Ailao Mountain in the west, Wuling Mountain and Xuefeng Mountain in the east, Yuechengling Mountain in the southeast, Dalou Mountain on the south bank of the Yangtze River in the north, and the mountainous area bordering Guangxi and Yunnan in the south. It is about 1000 km long from east to west and 400-800 km wide from north to south, with a total area of about 500,000 square kilometers.
Sichuan in a broad sense includes parts of the northern Yunnan-Guizhou Plateau.
