The middle route of the South-to-North Water Diversion Project is a major water conservancy project on the mainland that cost nearly 300 billion yuan and took 10 years to complete. This project diverts water from the Danjiangkou Reservoir in the upper reaches of the Han River, a tributary of the Yangtze River, and traverses the vast areas of northern China along the three water diversion routes of Funiu Mountain and the eastern foot of Taihang Mountain, bringing the abundant water resources of the Yangtze River system to the central and western regions of North China where water is scarce, thus ending the long-standing problem of water shortage in some areas in the north.
The 1,276-kilometre-long man-made waterway, which starts in Xiangyang City, Hubei Province, passes through Henan and Hebei provinces, and finally reaches Miyun District, Beijing, is widely praised as one of the longest man-made canals in the world today.
The Danjiangkou Reservoir in Hubei Province, the water source of the middle route of the South-to-North Water Diversion Project, is an important freshwater source in the central and southern regions of the mainland and the core water source of the middle route of the South-to-North Water Diversion Project. Danjiangkou Reservoir is a place that is very suitable for vacation and tourism, with beautiful scenery and beautiful scenery of the lake and mountains, surrounded by mountains, and beautiful scenery. Around the Danjiangkou Reservoir, we can see many shallow wetlands, which are important parts of the freshwater lake ecosystem and play a very important role in maintaining the ecological balance.
Since the official opening of the middle route of the South-to-North Water Diversion Project, in order to ensure the quality of water delivered to the north, the Hubei Provincial Government has always insisted on placing the construction and management of the Danjiangkou Reservoir, a water source protection area, in an important position and attaching great importance to this.
The provincial government attaches great importance to the protection of water resources, so they have organized multiple departments such as water conservancy and environmental protection to jointly implement the strictest level of protection for reservoirs. In order to ensure that the ecological environment around the reservoir is not damaged, they have completely banned all activities that may damage the ecological environment, and stationed a large number of monitoring personnel to use modern equipment to carry out continuous monitoring of water quality 24 hours a × 7 hours, so that any water quality problems can be found in time and effective measures can be taken, so as to ensure that the quality of water sources is always stable above the national secondary water quality standard, and ensure the safety and health of the people.
In the construction, operation and management of the middle route of the South-to-North Water Diversion Project, the Hubei Provincial Government has played an important role in the source of the water. They not only provided a large amount of water sources, but also invested a lot of manpower and material resources in the construction and management of the project, making great contributions to the smooth progress of the middle route of the South-to-North Water Diversion Project. Similarly, the governments of Henan and Hebei provinces have also actively engaged in the construction, operation and management of the middle route of the South-to-North Water Diversion Project.
They have provided a large amount of water source support to the Hubei Provincial Government, where the water source is located, and invested a lot of manpower and material resources in the construction and management of the project, making great contributions to the smooth progress of the middle route of the South-to-North Water Diversion Project.
Located in Henan Province, the middle route of the South-to-North Water Diversion Project is about 500 kilometers long, traversing most of the province, and it undertakes the heavy responsibility of daily inspection and supervision. Hebei Province is the terminus of the middle route of the South-to-North Water Diversion Project, and the water conservancy project here is responsible for the rational dispatch and use of water resources transported from the south, and gives priority to ensuring the drinking water needs of local residents, providing an important water resource guarantee for the economic development and residents' lives in Hebei Province.
Thanks to the close coordination, mutual support and joint efforts of the three provincial governments, the middle route of the South-to-North Water Diversion Project has been constructed with high standards and high quality, and has achieved efficient and stable operation. The successful implementation and effective operation of the middle route project has not only effectively alleviated the problem of water shortage in the northern region, provided high-quality and clean domestic water for hundreds of millions of residents, but also significantly improved the ecological environment, economic and social development of the cities along the project.
In order to ensure the water quality of the middle route of the South-to-North Water Diversion Project to the north and effectively prevent the negative impact of various fishing activities and fishing behaviors on the water body, the management measures of a total fishing ban have been officially implemented along the project since the official opening of the water in 2014, which has played a vital role in ensuring the safety of water quality and protecting the drinking water safety of the people.
The 1,276-kilometre man-made waterway, known as the South-to-North Water Diversion, covers the mainland's main canals, starting from the Danjiangkou Reservoir, where fishing and fishing are strictly prohibited.
The middle route of the South-to-North Water Diversion Project is located at the source of the Danjiangkou Reservoir, and the local government has carried out the strictest first-class water source protection for the water quality of the reservoir. Through scientific management and protection, the water quality of the reservoir has reached the second-class water standard stipulated by the state, providing a strong guarantee for the safety of the water source of the South-to-North Water Diversion Project.
In order to prevent pollution of water sources, the Hubei Provincial Government has sent a large number of monitoring personnel to conduct strict inspections, and used online water quality monitoring equipment to monitor various indicators in the water body around the clock, so as to strictly prevent environmental protection from the source.
Our main purpose is to ensure that the water source of the project is protected in an all-round way, so as to deliver high-quality and clear drinking water to the northern region, and better protect the health and life safety of the people.
In order to ensure the safety of water quality and the balance of the ecological environment, in addition to the protection of water sources, the project has also taken a variety of measures, including the full implementation of fishing bans in major rivers, prohibiting foreign fish and bait residues from entering artificial waterways, so as to prevent them from causing damage to aquatic life. At the same time, the project also strengthens the protection of fish resources, restores and increases the number of aquatic organisms through breeding and release, and maintains the ecological balance of artificial waterways.
On both sides of the river, the construction team carefully designed an ecological isolation zone, and poured concrete at the bottom and on both sides of the isolation zone, in order to minimize the pollution that the external environment may cause to the water body. According to the follow-up monitoring, the pollution indicators of the current water body have stabilized at a low level, which is enough to prove that this measure has achieved the desired effect.
In the future, the relevant authorities will not only continue to strengthen the control of the river, but also further strengthen the supervision and inspection of related activities, so as to strictly limit those behaviors that may adversely affect the river and water quality, and ensure the sustainable development of our environment and ecological environment.
The completion of the middle route of the South-to-North Water Diversion Project has brought significant changes to the ecological environment along the project, and the ecological environment along the project has been continuously tracked and monitored, and the changes in the ecological environment along the project have been further understood. According to the monitoring data, the water quality of the middle route of the South-to-North Water Diversion Project has generally remained stable, and the aquatic organisms are rich and diverse.
According to the latest statistics, the number of fish species in the project area has increased from 19 to 23 species. Among the new fish species, many farmed fish have been discovered, such as koi, goldfish, and so on. The appearance of these fish fully shows that the ecosystem in the project area is gradually forming, providing a more stable living environment for aquatic organisms.
What surprised the experts even more was that some of the fish in the midline project were growing so fast that there were some jaw-dropping fish growths. The growth rate of wild eel is astonishing, and there have been examples of a cod reaching a length of 1.68 meters and weighing more than 100 catties, which is very rare in the past.
According to relevant statistics, in the ecosystem of this large artificial water system, grass carp, one of the four major carp, can grow to an astonishing 2 meters or more. This finding not only provides more evidence for research, but also further confirms the complexity and diversity of this ecosystem. On the other hand, fish such as carp and catfish, which have a long history, also have great potential for growth, indicating that this ecosystem is rich in biological diversity and has an excellent growing environment.
A local fisherman and photographer once spotted an unknown fish more than 2 meters in length during a sea trip. This fish resembles a shark, but it is quite different from a normal shark. The fish is larger than the average shark and has a streamlined appearance, with a tan body, a slightly lighter ventral surface, darker fins than the body, and a pronounced fork in the tail.
The unknown fish swam rapidly above the surface of the water and seemed to be extremely vigilant about its surroundings.
Although some of the individual fish are huge, experts have assessed that even if they are more abundant, they do not pose a major impact on the local ecosystem. Some statistics show that the frequency and number of large fish entering artificial canals from reservoirs are effectively controlled at a low level, so in this case, we do not have to worry about the impact of these fish on the ecological environment.
Through the joint efforts and strict supervision of the water conservancy and environmental protection departments, the area of the Middle Route Project will be able to maintain biodiversity and ecological balance for a long time, and at the same time bring a major impetus to social and economic development, and play an important role in safeguarding national security and improving people's livelihood.
When designing the middle route of the South-to-North Water Diversion Project, many experts were concerned that large quantities of fish would enter the artificial canals from the reservoirs, disrupting the ecological balance of the area. In order to reduce the occurrence of this situation, a special fish blocking facility has been added at the head of the canal, and the size of organisms passing through is strictly controlled by using strainers.
After regular testing, we found that the filtration system was operating very effectively, and the frequency and abundance of medium and large fish flowing into the canal were kept at a low level.
In addition to physical isolation, the relevant departments have also established a new mechanism for scientific and systematic biological monitoring and control. They regularly use methods such as sound and light to attract fish concentrations, and then selectively fish for individuals that are oversized; At the same time, according to the composition of the fish, an appropriate amount of carnivorous fish and algae-eating fish will be released into the artificial river channel in a timely manner.
This results in a complex food chain system that achieves a dynamic balance between population sizes. In addition, when necessary, we will artificially introduce natural enemies of fish, such as water birds, turtles and turtles, etc., to give full play to their ecological regulation functions.
With scientific supervision and a variety of measures, an artificial ecosystem has been formed in the middle route of the South-to-North Water Diversion Project. The system is internally stable, organically connected, and at the same time relatively closed, which can avoid the damage of alien fish to the natural water body.
Experts said that according to the current regulatory model, the middle line project will not have a significant negative impact on the local ecological environment.
After ten years of construction and operation, the middle route of the South-to-North Water Diversion Project has delivered nearly 40 billion cubic meters of high-quality water resources to the north, equivalent to the total reserves of more than 2,000 West Lakes.
These high-quality drinking water from the south directly benefit hundreds of millions of people north of the Yellow River Basin, and greatly alleviate the long-term water shortage in the northern region.
As a major water conservancy project across provinces, the middle route of the South-to-North Water Diversion Project has successfully played an important role in alleviating water shortages in the north and improving the ecological environment. It profoundly embodies the construction tenet of "using water to relieve surpluses, and using water to relieve the depletion of roads".
In the future, the provincial government departments of the three provinces will continue to strengthen cooperation and continue to promote water quantity dispatch, water quality monitoring, ecological protection and other aspects, so that more cities and residents can effectively benefit from this project.
In this process, the relevant departments will further improve the management mechanism and strictly control the impact of human activities on the ecological environment of the project area. Through the organic combination of scientific monitoring and protection measures, a relatively independent and vibrant ecosystem will be formed in the middle line of the South-to-North Water Diversion Project, so that the clear water source will continue to extend to the northern land.
