红色预警频发：中国防洪能力是否跟得上极端天气？
China recently issued its first red alert of the year as torrential rains swept across southern and central regions, triggering floods and landslides. The extreme weather disrupted transportation, forced evacuations, and raised urgent questions about the country's flood preparedness. With climate change intensifying rainfall, the central debate is whether China's current infrastructure and emergency protocols can keep up with the escalating threats.
Proponents point to China's significant investments in flood control. The Sponge City program, launched in 2015, aims to make urban areas absorb 70% of rainwater through permeable surfaces, green roofs, and wetlands. Dozens of pilot cities have implemented such measures. The Three Gorges Dam, with a flood control capacity of 22.15 billion cubic meters, has demonstrably reduced downstream flooding risks. Additionally, a sophisticated four-tier warning system—where red signals the highest danger—enables timely evacuations. Officials argue that these integrated measures have prevented far worse outcomes during recent storms.
