Provinces and regions spanned by the South-to-North Water Diversion Project

The east-line project draws water from the Yangtze River from Jiangdu, Yangzhou, Jiangsu Province, in the lower reaches of the Yangtze River, and uses the Beijing-Hangzhou Grand Canal and its parallel rivers to lift water northward step by step, and connects Hongze Lake and Luo Lake, which play a role in regulating and storing. Ma Lake, Nansi Lake, Dongping Lake. After leaving Dongping Lake, water is transported in two ways, one way to the north, crossing the Yellow River through a tunnel, and flowing through Shandong and Hebei to Tianjin. The main water transmission line is 1,156 kilometers long; all the way east, the economic south transports water to Yantai and Weihai, and the water transmission line is 701 kilometers long. The middle line project diverts water from the Danjiangkou Reservoir after the Hanjiang River, a tributary on the north bank of the middle reaches of the Yangtze River, was dammed and expanded. It spans the four major river basins of the Yangtze River, Huaihe River, Yellow River, and Haihe River, and can basically flow to Beijing and Tianjin. The total length of the main water transmission line is 1,267 kilometers. The Western Line Project builds dams and reservoirs in the upper reaches of the Tongtian River, the tributaries of the Yalong River and the Dadu River in the upper reaches of the Yangtze River, and digs water transmission tunnels through the Bayan Har Mountains, the watershed between the Yangtze River and the Yellow River, to divert water from the Yangtze River into the upper reaches of the Yellow River and replenish the Yellow River. The shortage of water resources mainly solves the water shortage problem involving the upper and middle reaches of the Yellow River in Qinghai, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi and other areas and the Guanzhong Plain of the Wei River. During the 50 years of planning, the overall plan of the South-to-North Water Diversion Project will be implemented in three phases, with a total investment of 486 billion yuan.

West-East Gas Transmission: The gas transmission pipeline of the West-East Gas Transmission Project starts from Lunnan, Xinjiang in the west, and ends at Baihe Town, Shanghai in the east, passing through 10 provinces, autonomous regions, and municipalities directly under the Central Government (Xinjiang, Gansu, Ningxia, and Shaanxi). , Shanxi, Henan, Anhui, Jiangsu, Zhejiang, Shanghai), with a total length of about 4,200 kilometers and an investment scale of more than 140 billion yuan. It is currently the longest and largest diameter gas transmission pipeline in my country. , is the natural gas pipeline with the longest distance, the largest pipe diameter, the largest investment, the largest gas transmission volume, and the most complex construction conditions in China. The pipeline has a diameter of 1016 mm, a design pressure of 10 MPa, and an annual designed transmission capacity of 12 billion cubic meters. The entire line adopts automated control, and the gas supply range covers the Central Plains, East China, and the Yangtze River Delta.

"West-East Gas Transmission" has two concepts: broad and narrow. Broadly speaking, there are six major petroleum-bearing basins in the central and western regions of my country, including the Tarim, Junggar, Tuha, Qaidam, Ordos and Sichuan basins. The predicted natural gas resources are 22.4 trillion cubic meters, accounting for 10% of the national natural gas resources. 58.9% of the total volume of 38 trillion cubic meters; in a narrow sense, the West-East Gas Transmission refers specifically to the gas transmission project from Tarim, Xinjiang to the Yangtze River Delta. Natural gas resources discovered in the basin. The "West-East Gas Pipeline" project will build about 4,200 kilometers of pipelines to transport natural gas from the Tarim Basin to Shanghai and Zhejiang through Gansu, Ningxia, Shaanxi, Shanxi, Henan, Anhui, and Jiangsu, supplying civil and industrial gas to the provinces along the route. . The West-East Gas Pipeline Project started construction on July 4, 2002. By 2005, the West-East Gas Pipeline Project will be fully connected.

The West-East Gas Pipeline is China’s natural gas pipeline with the longest distance, the largest diameter, the largest investment, the largest gas transmission volume, and the most complex construction conditions
