In the context of climate change, the most immediate impact of global warming is the widespread occurrence of extreme weather events and natural disasters. Among all kinds of disaster events, heavy rain and flood disasters are the types of natural disasters with the fastest increasing frequency, the highest frequency and the greatest impact of secondary disasters. Therefore, this paper takes the three heavy rain and flood disasters in China as the research object to study the emergency management policy of flood and flood disasters. Taking the 7.20 rainstorm in Zhengzhou and the Zhuozhou rainstorm as examples, this paper has a detailed understanding of the emergency management situation during the occurrence of floods. It has found that different city governments have adopted different emergency management measures when dealing with the rainstorm and flood disasters, and there are their own problems, and put forward countermeasures against the existing problems.
