General layout of South-to-North Water Transfer Project

After years of investigation, planning and research, according to the topographic and geological conditions between the Yangtze River and the water-deficient areas in the north, three water transfer routes were planned in the lower, middle and upper reaches of the Yangtze River, forming the overall planning layout of the east, middle and west lines of the South-to-North Water Transfer Project. The three water transfer lines have their own main tasks and water supply scope, which can complement each other and cannot replace each other.

1, East Route Diversion Project

The water from the Yangtze River is pumped near Yangzhou in the lower reaches of the Yangtze River, and the Beijing-Hangzhou Grand Canal is used and expanded to lift the water to the north step by step, passing through Hongze Lake, Roman Lake, Nansi Lake and Dongping Lake, passing through the Yellow River near You Shan, then flowing by itself, passing through the neighboring canals and South Canal, and reaching Tianjin. The length of the water conveyance trunk line is 1 150km, including 660km south of the Yellow River and 490km north of the Yellow River. The water level of Dongping Lake, the highest point in the whole line, differs from that of the pumped river by 40m, and a 13 cascade pumping station is built with a total lift of 65m.

The water supply scope of the East Line Project covers the eastern part of the Huang-Huai-Hai Plain, including northern Jiangsu, northern Anhui, Shandong, Heilonggang, Hebei, Yundong and Tianjin. The main task is water supply, and there are also comprehensive utilization benefits such as shipping, flood control and waterlogging elimination.

Jiangdu Pumping Station was built in Jiangsu Province 196 1. After continuous expansion and extension, the current water transfer capacity of Jiangbei in Jiangsu is 400 m3/s, the annual pumping capacity is about 3.3 billion m3, and the water can be delivered to Nansi Lake by 30 m3/s, with a water volume of 200-400 million m3. The installed capacity of the pumping station is 6.5438+0.4 million kilowatts. On this basis, the East Route Water Transfer Project can gradually expand the scale of water transfer and extend northward. The total planned scale of the project is river pumping flow1000m3/s; The annual water supply is 654.38+08.6 billion m3, including 400 m3/s across the Yellow River and 9 billion m3. The total installed capacity of the pumping station is 880,000 kilowatts, and the average annual electricity consumption is 3.5 billion kilowatt hours. According to the forecast of water supply and demand in the receiving area, the planned project scale is planned to be implemented in three steps. See Table 2 for details.

2. Mid-line water transfer project

Water is diverted from Danjiangkou Reservoir in Hanjiang River. The main water conveyance canal starts from the head sluice of Taocha Canal, runs along Funiu Mountain and Taihang Mountain piedmont plain, crosses the Yangtze River, Huaihe River, Yellow River and Sea on the west side of Beijing-Guangzhou Railway, and then flows to Beijing and Tianjin by itself. The length of main water conveyance canal is 1246km, and that of Tianjin main water conveyance canal is 144 km.

The water supply scope of the mid-line project covers Beijing, Tianjin, North China Plain and parts of Hubei and Henan provinces along the line. The main task is urban life and industrial water supply, taking into account agriculture and other water use. The main canal of water conveyance is not combined with navigation.

Hanjiang River is the water source of the Middle Route Water Transfer Project. The average natural runoff of Hanjiang River Basin for many years is 5965438 million m3. At present, the actual water consumption of all kinds of water in the basin is 3.7 billion m3, accounting for only 6%, which is rich in water resources and sufficient for water diversion to the North. The average natural inflow of Danjiangkou Reservoir for many years is 40.9 billion m3, accounting for 70% of the whole basin. At present, the reservoir has begun to take shape, which has brought into play the benefits of flood control, power generation, irrigation and shipping, and has initially met the conditions for water transfer. After the later project is completed according to the original plan, the flood control standard in the middle and lower reaches of the Han River can be improved, and the amount of water transferred to the north can be increased. In the feasibility study stage, considering the need of water diversion in the middle and lower reaches of the Han River and improving flood control standards, it is suggested that Danjiangkou Dam be raised to the later scale, and local compensation should be implemented in the middle and lower reaches of the Han River in the near future, with water diversion of 65.438+045 billion m3, and finally comprehensive management of the middle and lower reaches will be implemented, with water diversion of 22 billion m3. See Table 2 for the phased implementation plan of the Central Line Project.

3. West Line Water Diversion Project

The west line water transfer project transfers water from the main tributaries in the upper reaches of the Yangtze River to the upper reaches of the Yellow River. The water diversion project plans to build dams and reservoirs in the upper reaches of Tongtian River, Yalong River and Dadu River, and the water diversion tunnel will cross the Yangtze River and Yellow River watershed and enter the Yellow River. The average annual water transfer is145 ~19.5 billion m3, of which Tongtian River is 55 ~1/kloc-0.0 billion m3, Yalong River is 4 ~ 4.5 billion m3 and Dadu River is 5 billion m3. The water supply scope of the West Line Project includes Qinghai, Gansu, Ningxia, Inner Mongolia, Shaanxi and Shanxi provinces (regions). The main task is to supplement the shortage of water resources in the Yellow River and solve the problems of industrial, agricultural and animal husbandry production in northwest and western North China, as well as water use for people and livestock in urban and rural areas.

The Central Committee of the Communist Party of China the State Council deliberated and approved in principle the master plan of South-to-North Water Diversion Project, which has attracted worldwide attention, will be transformed from the planning stage to the implementation stage. Here is a brief discussion on the possible benefits of related listed companies.

The overall layout of the South-to-North Water Transfer Project is divided into three water transfer lines: the west line, the middle line and the east line, which are connected with the Yangtze River, the Yellow River, the Huaihe River and the Haihe River respectively. The East Route Project uses the existing water diversion projects in Jiangsu Province to draw water from the Yangtze River in Jiangdu and Yangzhou in the lower reaches of the Yangtze River, and uses the Beijing-Hangzhou Grand Canal and its parallel rivers to gradually pump water northward, connecting Hongze Lake, Roman Lake, Nansi Lake and Dongping Lake to play a role in storage and regulation. The middle line project takes water from the head sluice of Taocha Canal in Danjiangkou Reservoir, passes through the watershed of Yangtze River and Huaihe River, crosses the Yellow River at the western edge of Huang-Huai-Hai Plain, and continues northward along the west side of Beijing-Guangzhou Railway. The West Line Project builds dams and reservoirs in the upper reaches of Tongtian River, Yalong River and Dadu River in the upper reaches of the Yangtze River, and tunnels are dug to introduce the Yangtze River water into the upper reaches of the Yellow River. As the largest water conservancy project in the world so far, its investment scale is extremely amazing. The Sanyanghe project in Jiangsu section, Jiping main canal project in Shandong section and Danjiangkou reservoir dam heightening project of Rudong Line Phase I started first, and the overall static investment reached 65.438+0548 billion yuan. Such a huge investment will promote the development of the national economy for a long time to come, and related industries will also achieve greater development. For the listed companies involved, it is reasonable to improve their performance.

First of all, listed companies in infrastructure will get the most direct benefit. As the South-to-North Water Diversion Project is a super-large water conservancy infrastructure, the project scale is large, the construction period is long, and the total investment, complexity and arduousness exceed those of the Three Gorges Project, which requires the construction unit of the project to have considerable scale advantages and management and technical level, and large-scale construction enterprises at the national level will inevitably become the first choice, especially listed companies that have participated in major projects before. Road and Bridge Construction, China Railway Second Bureau, Tunnels, Gezhouba and other companies are expected to be the beneficiaries of this project.

Secondly, building materials and steel companies will get sales opportunities. Because of the huge project, there is a great demand for products such as steel and cement, especially high-quality cement. Considering the transportation radius of cement enterprises, Jidong Cement and Lion Head should gain a certain market share. The demand for steel will be diversified, which will have a greater impact on the whole industry.

Thirdly, heavy machinery manufacturing enterprises and water pump manufacturing enterprises have both opportunities and challenges. According to the introduction of the Major Equipment Center of the State Economic and Trade Commission, the East Line Project needs large pumping station equipment with low lift, large flow and high reliability. Due to the complex address of the west line project, full-face roadheader is needed for construction. No domestic enterprise can produce the above-mentioned construction equipment, so it is necessary to seek cooperation with foreign investors by means of introduction, cooperative production or pure import. For domestic related enterprises, taking advantage of this favorable opportunity to cooperate with foreign businessmen can not only improve their own technical level and enhance their future competitiveness, but also obtain direct profits from the procurement of the South-to-North Water Transfer Project. Tianyi Technology, Xugong Technology and Xiamen Industrial Co., Ltd. all belong to this category.

Finally, listed companies in urban water supply and infrastructure will also benefit from it. Because part of the funds of the South-to-North Water Transfer Project will be solved by raising the water price in the receiving area, and sewage treatment is the leading indicator of water transfer, listed companies engaged in urban infrastructure construction, especially sewage treatment and water supply, will have profit expectations. Here, entrepreneurship and environmental protection are the most representative.

In addition, for water-dependent companies in water-deficient areas, long-term benefits are self-evident, and large software manufacturers will also benefit from the overall design of the project. For enterprises with heavy water pollution, although it has been improved for a long time, short-term pollution discharge investment is bound to be detrimental to the short-term production of enterprises and will have a certain impact on the short-term performance of enterprises, such as paper enterprises.
