What should I do if fish migrating upwards encounter a 63-meter-high dam?
At the Huangjinxia Water Conservancy Project of the Han-Wei River Diversion Project in Hanzhong City, Shaanxi Province, a 1908-meter-long ecological fish channel extends upward along the dam. The water replenishing canal, fish collecting canal, and fish inlet hole have entered the spawning period, and about 3000 fish migrate smoothly here every day. Staff introduced: "At the beginning of project planning and design, we fully considered the migratory and spawning characteristics of fish in the Han River, built ecological fish channels, and opened up fish migration channels." Today, ecological protection planning and design such as fish roads, bird roads, culverts, and "green bridges" are becoming the "standard configuration" for major project construction.
Ecological details in major project construction provide a unique perspective for understanding high-quality development.XiJinpingThe General Secretary gave important instructions on the start of the construction of the Sichuan-Tibet Railway, emphasizing "scientific construction, safe construction, green construction, and high-quality promotion of project construction"; presided over a symposium on promoting the high-quality development of the follow-up project of the South-to-North Water Diversion Project, pointing out that "adhere to the system concept and use the system theory The ideological method of analyzing problems, properly handle the relationship between open source and throttling, stock and increment, time and space, and maximize the comprehensive benefits of the project." From bays to mountaintops, from plains to deserts... the construction of major projects is moving from "green" to "new".
From the perspective of overall planning, it is not difficult to understand the positive interaction of "high-quality development and high-level protection." The Qinghai-Tibet Railway, the plateau railway with the highest altitude and longest line in the world, invested 1.54 billion yuan in ecological protection along the line at the beginning of its construction. It also set up 33 special channels for wild animal migration. It is strictly prohibited to whistle when trains pass by, and every effort is made to reduce interference with wild animals.
"Accelerating the construction of railways, highways and other major infrastructure" is an inevitable requirement to improve people's livelihood and develop the economy;"promoting the protection of biodiversity on the Qinghai-Tibet Plateau" is a responsible mission that will benefit the future and benefit the world. Plan from the perspective of harmonious coexistence between man and nature, based on the carrying capacity of resources and environment, continuously shape new driving forces and new advantages for development through high-level environmental protection, effectively reduce the resource and environmental costs of development, and continue to enhance the potential and stamina of development. Only then can we simultaneously improve economic, social, and ecological benefits.
In preparing for a rainy day, there is also a dialectical relationship between the overall situation and the local situation, the current situation and the long-term, and the macro and micro situation. Major project construction often has heavy tasks and long construction periods. Is it worth it "time-consuming and laborious" ecological protection and restoration? Whether it is worth it depends on calculating big accounts, long-term accounts, overall accounts, and comprehensive accounts.
The high-speed railway Xiongan Station in Hebei Province consists of 17,700 polysilicon photovoltaic panels, with an average annual power generation of about 5.8 million kilowatt-hours. It can save 1800 tons of standard coal and reduce 4500 tons of carbon dioxide emissions every year, equivalent to 12 hectares of tree planting; During the construction of the Hong Kong-Zhuhai-Macao Bridge, the number of Chinese white dolphins increased from 1200 to more than 2000. In the words of the builders, this super project "is not only a milestone for China to move from a bridge power to a bridge power, but also a symbol of mankind. A monument to harmonious coexistence with the ocean." This enlightens us that whether we are pursuing reform or seeking development, we must have the "biggest country" in mind, coordinate the short, medium and long-term goals, think about issues and advance work from the perspective of overall interests, fundamental interests, and long-term interests.
Through innovative breakthroughs in major projects, it is easier to understand the profound connotation of "new productivity itself is green productivity." The entire control project of the Shenzhong Corridor-the submarine immersed tube tunnel has a total length of 5035 meters and requires floating transportation of 50 kilometers from the immersed tube prefabrication factory to the installation area. The project team creatively proposed a plan to build an integrated ship for immersed tube transportation and installation. Compared with the traditional towing scheme, it can reduce the amount of dredging and dredging in the channel by more than 10 million cubic meters and reduce exhaust emissions by about 1 million cubic meters. The architectural beauty of major country projects complements the natural beauty of Lingdingyang.
Chinese-style modernization is a modernization in which man and nature coexist harmoniously. The "Decision" of the Third Plenary Session of the 20th Central Committee of the Communist Party of China stated: "We must improve the institutional system of ecological civilization, coordinate the promotion of carbon reduction, pollution reduction, green expansion, and growth, actively respond to climate change, and accelerate the improvement and implementation of the concept that lucid waters and lush mountains are invaluable assets. Institutional mechanism." To strive to promote innovation in development methods, we must firmly establish and practice the concept that lucid waters and lush mountains are invaluable assets, accelerate green technological innovation and the promotion and application of advanced green technologies, promote the deep integration of industrial digitalization and intelligence with greening, and cultivate high-quality development. Green background.
In the construction of major projects, there are ecological considerations and development considerations. Not only focusing on the overall situation, crossing mountains and seas, chasing the wind and the sun, but also starting from a small place, making first moves and taking the initiative, we will surely create more miracles on earth and write a new chapter in Chinese-style modernization in which man and nature coexist harmoniously.
