The flood happened in Zhengzhou on the evening of July 20 was shocking and grievous. The new reported that this is a rainstorm “never seen in a thousand years”, however, I don’t think so. Due to the global climate change, the number of rainfall is bound to continue to increase and refresh the record extreme value in the future. We should be more vigilant to this fact than talking about “once in a hundred years” or “once in a thousand years”.
The increase of evaporation in the ocean and the increase of cloud cover in the air due to the global warming are sure to constantly refresh the extreme values of the existing records of rainfall. But have our buildings, especially our urban construction, made certain preparations?
We know that urban construction is still based on the consideration of industrial civilization. Both standards and norms are based on the experience of industrial civilization. However, what we are facing today is a problem that cannot be solved by the experience of industrial civilization.
In the past, we thought that it was enough to withstand the flood and heavy rain that never happened in 50 years, or 100 years. But we need to see the changes today. The future will continue to impact and refresh the existing records. Therefore, our overall construction, changes and challenges must adhere to the guiding ideology with ecological civilization as the core, and fundamentally change our thoughts, ideas, methods, norms and principles. Only in this way can we solve the problems in the future.
The flood in Beijing and Wuhan a few years ago, the flood in Zhengzhou now… More and more serious problems will occur in more and more cities in the future. We should take this opportunity to seriously check the drainage and waterproof system of the subway; we should seriously and carefully solve the problem of Sponge City, not only the simple concept with industrial civilization; we should also learn new ideas, new concepts and new methods in the era of ecological civilization. Only in this way can we deal with the challenges of the future.
Even if it is the “once-in-a-thousand-year event”, we should think about it and get well preparation for it. Since it is not just this flood in Zhengzhou, in the past, the precipitation and wind have set new historical extremes in many places. So we hope that this time will serve as an important warning to our industry and relevant departments, to take immediate action and make immediate changes, avoiding this kind of disaster in the future.
