The origin of the Yellow River (Inner Mongolia)
the Yellow River reaches Hekou town in Tuoketuo County, Inner Mongolia, with a length of 3472 km and a drop of 3496 m, with an average gradient of about one thousandth. The basin area is 386000 square kilometers, accounting for 51% of the whole basin area. This section is rich in water and sediment, and contains abundant water resources. On November 4, 1280, Kublai Khan of the Yuan Dynasty sent Dushi to lead a team of people to the source of the Yellow River for official investigation and research. After several months of trekking, Dushi and his party arrived at Xingxiu sea and thought that this was the source of the Yellow River. In 1985, the Yellow River Water Conservancy Commission determined Maqu as the main source of the river according to the historical tradition and various opinions, and established the symbol of the river source at Maqu Quguo, 95 ° 59 & # 39; 24 " E, 35 ° 01 & # 39; 18 " n, in the southwest corner of youguzonglie basin.
3. Yellow River Bridge Construction
the first formal bridge on the Yellow River is Zhengzhou Yellow River Railway Bridge contracted by Belgium engineering company. The bridge was started in 1903 and completed in 1906. When the people's Republic of China was founded in 1949, there were only three bridges designed and constructed by foreigners on the Yellow River, including Zhengzhou Yellow River railway bridge, Luokou Yellow River Bridge and Lanzhou highway bridge. After the founding of new China, dozens of bridges have been built on the Yellow River, turning the natural moat of the Yellow River into a thoroughfare. Baotou Yellow River Highway Bridge is located at the south end of Baotou City, Inner Mongolia, with a total length of 810 meters and a width of 12 meters. It was the largest span continuous bridge constructed by multi-point pushing method in China at that time. The bridge was completed and opened to traffic in October 1983. 4. Resources of the Yellow River and distribution of fish resources: upper reaches and middle reaches of the Yellow River: the water flow is gentle and the resources of carp, crucian carp and catfish are abundant.
downstream: the most abundant fishery section, including estuarine migratory fish, channel fish, sedentary fish, semi salty fish and aquatic fish. The Yellow River Waterway in Inner Mongolia has a total length of 840 kilometers, with stable flow and good navigation conditions. The people of Inner Mongolia on both sides of the middle reaches of the Yellow River have a history of using the Yellow River for water transportation for thousands of years. In the early 1960s, with the rapid development of Railways and highways in western Inner Mongolia, the potential of water transportation was gradually ignored. Especially after the construction of Sanshenggong water control project in Hetao area, the middle and upper reaches of the Yellow River lost the benefits of water transportation. The Yellow River flows through the west of Inner Mongolia, from Shizuishan City in Ningxia to Hequ city in Shanxi, and flows through four leagues and three cities, with a flow of 830km and a drainage area of 143500km2.
the railway line in the Yellow River Basin of Inner Mongolia is mainly Baotou Lanzhou line, and a part of Beijing Baotou railway line, Hohhot Baotou section, as well as several railway branches.
during the period of the Republic of China: construction began in February 1921, and it was completed to Baotou in 1921, and the Beijing Baotou railway was opened to traffic.
the founding of new China: technical transformation was carried out in 1958, and double lines were built. The construction was suspended midway, and resumed in 1978. By 1984, Jining Hohhot was completed and put into use. Beijing Baotou railway belongs to the Hubao railway in the Yellow River Basin, with a length of 148 km. The construction of Huzhou Baotou section began in February 1921 and reached Baotou in January 1923. So far, the Beijing Baotou railway was completed and opened to traffic.
Yellow River Road Bridge: it was built in October 1955 and passed through more than 100 kilometers of desert. The Baotou Lanzhou line was handed over and put into operation in 1958, with a construction period of two years and nine months. In 1954, in order to support the construction of heavy industry in Baotou, a 175 km Baotou Bayan Obo railway line was built.
in 1956, the 38 km Baotou Shiguai railway line was built and put into operation in 1958. In 1959, the design and construction of electrification began. However, the project was stopped in 1961 and cost more than 10 million yuan.

the Haibowan Lasengmiao railway was built in 1958 and put into operation in 1961. The Wuda Jilantai railway was built in 1963.
in 1989, Baotou Shenmu railway, 173 km long, was built to develop Yimeng clean coal. This railway line crosses the Yellow River. At the same time, the third Yellow River Railway Bridge in Inner Mongolia was built at Daliuta. In 1990, the Baotou Zhungeer railway line was also under construction. The formation of the Yellow River, ancient ecology, Jiuqu Yellow River. The third, the cradle of the nation, living by water, the light of civilization, the ancestor of humanity, the fourth, the three-dimensional landform and geographical sand table of the Yellow River. The fifth, the canyon of the Yellow River. One of the top ten canyons in China. The first, the Qingshui River. 1. Rich and flexible water scenery wonders. 2.
