What places in our country are called "treasure basins"
The regions in my country known as the cornucopia include: Junggar Basin, Sichuan Basin, and Qaidam Basin.
Junggar Basin:
The Junggar Basin (Chinese Pinyin: zhǔn gá ěr pén dì, English Junggar Basin), located in the north of Xinjiang, China, is the second largest inland area in China basin. The Junggar Basin is located between the Altai Mountains and the Tianshan Mountains, with the western Junggar Mountains to the west and the foothills of Beita Mountain to the east. The basin is in the shape of an irregular triangle, with the terrain tilting to the west. The north is slightly higher than the south. The lake surface elevation of Ulungu Lake (Brento Sea) in the north is 479.1 meters, the lake surface of Manas Lake in the center is 270 meters, and Lake Aibi in the southwest The lake surface is 189 meters, the lowest point in the basin. There are several gaps on the west side of the basin, such as the Irtysh River Valley, the Emin River Valley and the Alashankou. The westerly airflow enters through the gap and brings precipitation to the basin and surrounding mountains. ,
Sichuan Basin:
The Sichuan Basin is one of the four major basins in China; it is also called the envelope basin and the purple basin. It is surrounded by connected mountains. It is located in the south-central part of the Asian continent, the heartland of China and the middle section of the eastern edge of western China. It has a total area of more than 260,000 square kilometers and can be clearly divided into two parts: the edge mountains and the bottom of the basin. The areas are approximately more than 100,000 and 160,000 square kilometers respectively; the edge mountain area generally has 2 to 5 vertical natural zones from bottom to top.
The altitude of the mountains in the Sichuan Basin is mostly between 1,000 meters and 3,000 meters; the basin bottom is low, with an altitude of 200 meters to 750 meters. Red rock systems are widely exposed on the surface, called red basins. The western part of the basin has low terrain and fertile soil. Chengdu in the northwest has the Dujiangyan Irrigation Project. The eastern part of the basin is composed of low mountains and hills. The central part of the basin is composed of square hills, accounting for 62% of the total area, and is mainly composed of purple sandstone and shale. The basin also contains coal, oil, natural gas, salt, apatite, sulfur and other minerals.
The bottom of the Sichuan Basin is divided into three parts: parallel ridges and valleys in eastern Sichuan, hills in central Sichuan, and Chengdu Plain in western Sichuan. The main cities in the basin include Chengdu, Mianyang, Luzhou, Nanchong, Zigong, Deyang, Guangyuan, Suining, and Neijiang, Leshan, Yibin, Guang'an, Dazhou, Ya'an, Bazhong, Meishan, Ziyang, Zunyi and Bijie in Guizhou Province and Zhaotong in Yunnan Province, etc. The climate of the basin is generally considered to be a humid subtropical monsoon climate, but most areas of the basin are similar to a temperate oceanic climate.
Qaidam Basin:
Qaidam Basin is one of the three major inland basins in China. It is a closed huge intermountain fault basin. It is located in the northwest of Qinghai Province and the northeast of the Qinghai-Tibet Plateau. It is surrounded by the Kunlun Mountains, Qilian Mountains and Altun Mountains, covering an area of approximately 250,000 square kilometers. "Qaidam" is Mongolian, meaning "salt lake".
