ABSTRACT

In July 2021, a huge flood occurred in Zhengzhou, China, which caused huge production, living and economic losses. After investigating this city, the dats shows that in order to deal with the occurrence of urban floods, the government has listed Zhengzhou as a pilot sponge city in China, and has invested 5 billion yuan to build it. But why didn’t the city successfully resist the flood? With this problem, I did a series of research. The data in the survey show that in this flood, the water that can be absorbed by urban greening and drainage facilities accounts for only 32% of the precipitation, that is, more than half of the precipitation is retained in the city. In fact, human demand for water is growing, and the increasing amount of flood water maybe should not be regarded as a disaster, instead?we can regard it as a resource endowed by nature.
