Since 1952, it has been demonstrated that various programmes have been proposed for the development of the yellow river's montenegrin gorge for different interests and considerations. The choice of level i, level ii or level iv development has been controversial。
(b) level i development, which refers to the establishment of only one dam and power station in the willow tree, with greater consideration given to the management of the yellow river and the achievement of such functions as agricultural irrigation, flood control and sand management, with hydropower development as a secondary objective
The secondary development is the construction of a small sound and a large willow tree, respectively, while the fourth development is the installation of a red mountain canyon, a five-voltage, a small sound and a large willow level 4。
The latter two programmes are more focused on generating capacity, in particular level iv development, with four hydroelectric plants. The problem, however, is that too many dams are set up, which will result in small reservoirs with little capacity to regulate water storage and flood prevention。
Other studies indicate that the development of the willow-level dam will occupy a significant amount of land and involve a large number of migratory movements, with 97 per cent of the inundated areas in gansu province; that the secondary development will also inundate over 100,000 acres of good and good land in gansu; and that the fourth development will reduce the inundated cropland by 95. 6 per cent and the migration by 93. 8 per cent。
Apparently, gansu did not want to flood large areas of land and relocate large numbers of villagers, and therefore recommended a level-iv development programme, while ningxia recommended a level-i development, which was repeatedly commissioned by both parties to scientific institutions。
“from the 1970s to the present, it has been difficult to decide, to argue. Without controversy, the small acoustic reservoir that was built in the 1970s has worked well.” in a paper, zhuang, former chief engineer of the gansu department of water, wrote:。
The proposed site was announced to move the project forward. According to the public notice, the total land proposed for the project is 119 hectares, of which 99 hectares are to be occupied by agricultural land, mostly in gansu. This also means that the ningxia willow-level dam development programme is being recommended at this stage。
Previously, gansu and ningxia had issued a circular on the prohibition of new construction projects and the transfer of people within the area of the water hub and inundation in the isthmus of the yellow river, covering 7 administrative villages in 3 townships in ningxia and 46 administrative villages in 12 townships (towns) in 3 counties (districts) in gansu。
Not only is the scope of the impact high, but the investment projected for the project is not low。
In 2021, the priority project investment plan disclosed by ningxia reform commission showed that total investment in the water hub project in the isthmus of montenegro was 35. 8 billion yuan; in 2023, total investment in the project was increased to 48 billion yuan; by 2024, total investment in the project was expected to have risen to 91. 5 billion yuan。
Why does it matter
What kind of project is it worth debating over 70 years of spending over $90 billion? It starts with the yellow river。
The yellow river is the second largest river in the country, feeding hundreds of millions of people through the nine provinces (districts) of qinghai, sichuan, gansu, ningxia, nepal, shanxi, henan and shandong. However, the yellow river basin is characterized by problems such as water scarcity and sanddos, heavy soil erosion, and fragile ecological environments, most typical of which is “on the ground”, i. E. Riverbeds above both banks。
Floods have been particularly devastating in the history of the yellow river and the situation of flood protection has been severe. Of these, the ningmong river is a part of the river where severe haze and flooding are common in the upper yellow river, but there is currently a lack of control backbone work and the existing standards for river defence work are low。

“the completion of the water hub project in the isthmus of montenegro, which is managed with a high reservoir level of recharge, will significantly increase the temperature of the discharge, ensure a significant downswing of the zero temperature segment of the ningmong river, and achieve a basic solution to the problem of the ningsha river without sealing the river, and the upper implacing section of inner mongolia.” zhang guojun, the pre-work centre for the ningxia willow water hub, wrote。
Zhang guojun mentioned that the landing of the project would raise the flood control standard in the ningmong river sector from the current 20 to 50 years to 100 years。
In addition, the water hub of the isthmus of montenegro is also an important node for the north-west of the southern waters. The master plan for the north-south water project mentions that the west line project, in conjunction with the construction of a willow water hub on the yellow river dry stream, can provide water to areas of the western corridor of the gansu river adjacent to the yellow river basin and, if necessary, to the downstream of the yellow river. This willow water hub is described here as located in the canyon of the yellow river。
The zhang national army believes that using the reservoir of the isthmus of montenegro as a large source of water can also be effective in resolving conflicts in water use for life, production and ecology in the watersheds and in fundamentally addressing the problem of drinking water security for more than 5 million urban and rural people in the four provinces (districts) of gannimong。
In addition, the construction of the project will result in the addition of 20 million acres of resources for reclaimable land; the high-level water supply advantage of the project will allow for the self-flow of the water and irrigation areas that have been built in the surrounding province (district) of ganningmont to fundamentally change the long-term dependence on inflow of rations in the irrigation areas。
More than 90 per cent of the local water structure is agricultural, for example, in the town of xingtae, silver city, gansu province, near the project. According to studies, by 2035, the total water requirement in the county was 530 million cubic metres and, in the absence of a significant new source of water, 350 million cubic metres, a shortfall of 180 million cubic metres. Waterworks in the isthmus of montenegro and the north to west water project will help chongtai county to solve water shortages。
Of course, the effect of the water hub in the isthmus of montenegro is also directly reflected in electricity generation. According to the plan, the yellow river canyon hydro-centre power station, which has a total installed capacity of 2. 6 million kilowatts and an annual generating capacity of 7. 15 billion degrees, is a medium-sized hydroelectric power station that can provide more clean energy to surrounding areas。
Landing challenge
Since this year, information has been released on the water hub works in the isthmus of montenegro。
In march, the director of the yellow river commission, zhu ryon, stated in the learning times that “high standards for the construction of the ancient water hub will facilitate the early start of construction of the water hub in the isthmus of montenegro”。
In may, the standing committee of the national people's congress of the ningxia autonomous region studied the advancement of the water hub project in the isthmus of montenegro. The study group stated that the " recommendation for accelerated progress on the water hub project in the isthmus of the yellow river montenegro " had been prioritized by the office of the standing committee of the national people's congress as an opportunity to make early and significant progress on the project。
At this point, the project announced the location of the proposed site, and we were unable to receive a further response during our first call to the water department of the city of midway, the pre-work centre of the ningxia willow water hub。
It should be noted that the announcement of the proposed location does not imply that work is about to begin, followed by processes such as environmental impact assessment, land approval for construction projects and review of feasibility studies. It can be said that every link is a "hard bone to chew."。
The most appropriate solution to the problem is the relocation of tens of thousands of immigrants. “... According to the survey, the inundated area involved 96,000 acres of arable land, affecting a population of 73,000; in the event of the application of the treasury protection works, 95,000 acres of arable land were inundated, affecting 58,000 people.”
The data mentioned above were referred to in the paper " inundation and migration in the isthmus of montenegro " , published in 2023 by professor ishipaki of the faculty of geography and environmental sciences of the north-west pedagogical university, which is a possible impact of the first-level development programme。
