Protect the source of life of tens of millions of citizens and decode the wisdom code of world-class water sources. Recently, the School of Marine Science and Engineering, led by teachers He Haibo, Zhang Wenbing and Xu Ling, walked into the Shanghai Qingcaosha Reservoir and started an in-depth research journey to explore how this super reservoir can build a solid line of defense for urban water supply safety with the power of science and technology and ecology.
The water engineering miracle that Qingcaosha Reservoir has been conceived since the end of the 80s of the last century, and after more than 20 years of tackling, it was officially opened to water in 2011 and became the world's largest estuary river source reservoir in one fell swoop. Its astonishing effective storage capacity of 1.038 billion cubic meters and the high-quality water quality of the second class deliver the water of life to 13 million Shanghai citizens every day. With the core function of avoiding salt and accumulating desalinity, the Qingcaosha Reservoir is like a needle for urban water supply, supporting a solid guarantee in the complex hydrological environment of the Yangtze River Estuary.
During the field visit, the wisdom pulse of the reservoir was clearly visible. In front of the observation deck and the downstream gate, the engineer explained on the spot: the precise regulation of the upstream average daily water inlet of 15 million tons, the downstream drainage of 10 million tons, and the water supply of 5 million tons all depends on the intelligent brain of the three downstream gates; In the face of threats such as salty tides and algae, 30 real-time monitoring points covering the entire reservoir area have woven a net of heaven and earth, and combination punches such as physical interception, biological manipulation, and chemical dosing, combined with ecological research jointly carried out with universities, to resolve risks invisibly. What is even more amazing is that more than 700 acres of ecological shelter forest are like green barriers, and silver carp and silver carp become water scavengers, attracting rare fish such as Chinese sturgeon to inhabit and reproduce, painting a vivid picture of harmonious coexistence between man and nature.
In the interactive exchange, the spark of thinking continues to burst out. The engineers explained in detail the scientific response strategy for salty tide backflow in the North Branch, revealed the monitoring plan covering 90% of the area, and shared cutting-edge research on the integration of mechanism analysis and machine learning. This knowledge feast not only allowed the team members to touch the precise context of the urban water supply system, but also felt the ingenuity and responsibility of scientific researchers to protect water sources.
From grand projects to ecological pictures, from intelligent regulation to cutting-edge scientific research, this investigation by the Tracing Light Practice Team is not only an in-depth exploration of the miracle of Shanghai's water supply, but also a vivid ecological ideological and political lesson. In the future, the practice team will take this survey as a starting point to gather youthful wisdom, inject innovative momentum into the sustainable development of water resources, and let the youth power that protects water resources rush forward in the tide of the times!
