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.
有害藻华（HABs）是全球主要的环境问题之一，对水生生态系统、人类健康、海洋渔业和地方经济都有严重的影响。在过去的几十年里，中国海域的沿海水域发生了大量的 HAB 事件，这在世界上绝大多数沿海水域都很常见。在这里，我们报告了 21 世纪初中国海域 HAB 事件没有广泛增加的情况。2000 年至 2017 年期间，HAB 事件的发生频率和覆盖面积都以统计学上显著的速度减少。尽管有多种因素决定了 HAB 的爆发，但中国近海水质的改善和 21 世纪初海表温度的变化可能在 HAB 的减少中起到了重要作用。
