南海北部沿海夜光藻赤潮的生态模式研究

Studies on Ecology of Nactiluca scintillans Red Tide in North Coastal Waters of South China Sea

本文根据１９８０～１９９１年南海北部沿海发生的夜光藻赤潮资料，介绍了夜光藻的生物学特征．生态学特征，从夜光藻发生赤潮的起始、发展、维持和消亡四个阶段分析和探讨其发生机制，提出了夜光藻赤潮的生态模式。研究表明：夜光藻赤潮各阶段的消长过程受到物理、化学和生物因素的制约．这些因素在夜光藻赤潮发生的不同阶段所起的作用是不一样的，其发生机制仍然存在着生物地理学的差异等。

Based on the materials of Noctilura scintillans red tide which occured in North coastalwaters of South China Sea from 1980 to 1991.We have analysed and explored the mechanism ofred tide occurrence through the four stages:Beginning.Develoment. Maitenance and Disappear -ance during red tide period.The study shows that each stage is influenced by physical. chemicaland biological factors. All these factors play differcnt rolcs in different stagcs of the Noctiluca Sein-tillans red tide, There exist biogeographlcal diffcrences in the mechanism of red tide occurrence.
