| 英文摘要 | Conducting a comprehensive risk assessment for Harmful Algal Blooms (HABs) is a critical step toward effective management and the sustainability of coastal economies. This study establishes a novel risk assessment framework for red tide disasters in China by integrating long-term hazard patterns with coastal vulnerability. We compiled a 90-year dataset (1933-2023) of red tide events in China's coastal waters and developed a multidimensional hazard index based on the frequency, scale, duration, and causative species diversity of blooms. Regional vulnerability was evaluated using indicators of mariculture intensity, tourism revenue, and proximity to nuclear power plants. Our analysis reveals a predominance of dinoflagellate-related events (47.72 %) over those caused by diatoms (22.77 %). Since around 2000, the proliferation of toxic blooms has significantly increased the hazard level in the East China Sea, with a notable southward expansion in recent decades. Overall, high-risk areas were identified in the Bohai Sea, the North Yellow Sea, and the East China Sea. We discussed the combined impact of terrestrial nutrient influx and mariculture on HAB dynamics and proposed that dual-nutrient reduction strategy is crucial for mitigation. This study provides a scalable methodology and critical insights for targeted red tide management and policy-making. |
