赤潮是世界性的主要环境问题之一，给水生生态系统、人类健康、海洋渔业和当地经济带来严重后果。在过去的几十年里，中国海域经历了HAB事件的显著增加，这一事件在世界绝大多数沿海水域都是常见的。在这里，我们报告了21世纪初中国海域没有出现大范围增加的情况。在2000-2017年间，每年一度的卫生和环境卫生活动的频率和覆盖面积都以统计上显著的速度下降。尽管赤潮暴发的原因是多方面的，但21世纪初中国外缘海域水质的改善和海温的变化可能对赤潮的减少起到了重要作用。
Harmful algal blooms (HABs) are one of primary worldwide environmental problems with severe consequences for aquatic ecosystems, human health, marine fisheries and local economy. During the past few decades, coastal waters of China Seas have experienced a significant increase in the occurrence of the HAB events, which is common across the vast majority of coastal waters of the world. Here we report the absence of the widespread increase over the early 21st century in China Seas. Both frequency and coverage area of annual HAB events have decreased at statistically significant rates for the 2000–2017 period. Despite the multiple factors determining the outbreak of HABs, the improvement of water quality in the marginal sea off China and changes in the sea surface temperature in the early 21st century may play an important role in the decrease in the HABs.
