| 摘 要： | 近些年来，全球有害赤潮发生的频率、规模及其危害效应呈现逐渐上升的趋势。有害赤潮的形成受到赤潮原因种适应特征与竞争策略、水体富营养化状况，以及水文、气象等环境因子的影响。有害赤潮藻种可以通过产生毒素、改变水体理化特征等对人类健康、水产养殖和海洋生态系统带来危害。迫切需要协调人类活动与环境的关系，建立和发展赤潮应急治理技术，以降低有害赤潮的规模及其危害效应。我国近海有害赤潮问题近年来有加剧的趋势，而且有毒有害藻种形成的赤潮越来越多，对于我国近海赤潮演变的趋势与潜在危害效应应给予充分关注。

| Abstract: | Apparent global increase of harmful algal blooms (HABs) has been observed recently. Coastal eutrophication, long-term change of hydrological and meteorological parameters, as well as the adaptive and competitive strategies of HAB causative species, can affect the occurrence of HABs. Through producing toxins or high biomass, the HAB causative species pose potent threats on the health of human-beings, mariculture industry and natural ecosystems. It's necessary to develop HAB prevention and control measures to mitigate the impacts of HABs. In China, an increasing trend of both scale and impacts of HABs has been found over the last two decades. More and more toxic algal blooms are recorded. The succession pattern of major HAB causative species, and the potential impacts, should be given more attention. |
