河北省沿海赤潮的成因及调控对策研究

Harmful Algal Blooms in Coastal Hebei Sea: Causes and Mitigation Countermeasures

赤潮是河北省沿海地区主要海洋生态灾害之一。对河北省沿海赤潮的成因进行了剖析并提出调控对策。研究表明:河北省沿海赤潮发生的内因是存在赤潮生物;外因是具备适宜的环境条件,如近海海域富营养化、适量的微量元素和有机物以及水文、气象和海水理化因子的变化等。

Harmful algal bloom （HAB） is one of the major marine disasters in the coastal areas of Hebei. This study aimed to summarize the causes of HAB and put forward mitigation countermeasures against it. The result showed that the presence of species causing HABs was the basic internal cause and the external causes were that suitable growth and living environment for these species was provided by rich nutrients in offshore areas, proper microelements and organic materials as well as the appropriate hydrology, weather, physical and chemical factors of seawater.
