The Pearl River basin is highly susceptible to flood disasters due to its variable climate and complex river network,particularly in the middle and lower reaches and the Pearl River Delta.Since the start of the 21st century,the basin has witnessed rapid economic and social development.With the advancement of national strategies such as the Guangdong-Hong Kong-Macao Greater Bay Area,the Pearl River-Xijiang River Economic Belt,and the Hainan Free Trade Port,population and economic assets in the region are expected to grow and concentrate further.Simultaneously,global climate change has led to more frequent and severe extreme weather events,resulting in increasingly frequent,intense,and widespread regional and basin-wide flood disasters.The combined influence of these factors has significantly altered the flood control landscape in the Pearl River basin,amplifying the pressure on existing systems.Based on reviewing the current state and challenges of the basin's flood control and disaster reduction system,adapting to the new demands of high-quality economic and social development,and ensuring sustainable and secure development,this study conducts a systematic analysis of the evolving flood control demands,addressing key challenges in light of hydrological,engineering,and social changes.Targeted strategies to enhance the basin's flood control and disaster reduction capabilities are proposed,aiming to safeguard the Pearl River basin's stability,contributing to the broader goal of Chinese modernization.
