东海赤潮及其监视监测

赤潮是一种海洋生态异常现象，是海洋生态系统受损与退化的表征与警示。近20a以来，东海赤潮频发，且影响范围不断扩大、持续时间增长，并呈逐年上升趋势，在一定程度上制约了东海区沿海省市海洋经济的发展。开展有害赤潮常规监测和应急监视监测是当前赤潮监控中最为有效手段。本文系统回顾和总结了近20a来东海区赤潮发生特点，以及在东海区开展的赤潮监视监测工作，并对21世纪东海赤潮监视监测进行了简要展望。

HABs in East China Sea: Surveillance and monitoring

Harmful algal blooms(HABs) is one kind of the abnormal phenomena of marine ecology as a token early warning of degradation in marine ecosystem. In the last 20 years, HABs occurred frequently and increased year after year in ranges and lasting duration in East China Sea. To some extent, HABs restricted the development of marine economies along the coasts of East China Sea. HABs surveillance and monitoring are the most effective method in HABs monitoring and controlling for the time being. Both occurrence characteristics of HABs and related conductions and achievements of surveillance and monitoring in the last 20 years in East China Sea were reviewed systematically. In addition, a brief prospect on surveillance and monitoring for HABs in 21 century in East China Sea is also provided.
