China's prevention and response to flood and drought disasters
Flood and drought are the most serious disasters in China's natural disasters.Since the founding of the People's Republic of China,after more than 70 years of construction,a relatively complete flood and drought disaster prevention sys-tem combining engineering system and non-engineering system has gradually formed in China,and the flood and drought disaster prevention capability has reached the international medium level.In recent years,the established engineering sys-tem and non-engineering system play an important role in the defense of"July 23"extreme flood in the Haihe River basin,and the defense of drought disaster in Yangtze River basin in 2022,and other flood and drought disasters prevention and response.For the past few years,the national deaths and the ratio of direct economic losses to the GDP of the current's year caused by floods have shown an obvious downward trend,and the prevention of flood and drought disasters has achieved remarkable effectiveness.Affected by global climate change and human activities,flood and drought disasters in China are becoming more frequent,severer and wider.In order to deal with more extreme and abnormal flood and drought disasters,this article puts forward some ideas and suggestions such as constructing flood and drought disaster defensing matrix,per-fecting flood and drought disaster defense engineering system,constructing digital twin river basins,and improving laws and regulations and management system and mechanism.
