摘　　要：对1990年6月9～25日在东海赤潮多发区海域调查期间所观察到的5次中肋骨条藻赤潮的特点以及与环境要素变化的关系作了初步分析。结果表明:(1)中肋骨条藻是多发区海域夏季的敏感赤潮生物,风速减小、气压下降以及良好的海况条件有利于赤潮的发生;(2)赤潮发生时发生区边界存在明显的界面变化特征,这种空间界面的环境要素变化与赤潮发生的时间变化特点是一致的。This paper analysed the relationship between the red tide occurring characteristics and environmental factors by observing 5 times Skeletonema costatum red tides occurred in East China Sea red tide frequent area from June 9 to June 25, 1990. The result show : (1) Skeletonema costatum is the sensative red tide organism in red tide frequent area on Summer. Low wind velocity and air pressure, good sea condition will be beneficial to occurrence of red tide. (2) When red tide occurred ,the blooming area exists obvious border changing characteristics. The change of environmental factors in space is similar to those in time sequence.
