摘　　要：本文研究了海水养殖池塘实验围隔中海洋原甲藻水华暴发前、后水化条件的变化，得出了如下结果：海洋原甲藻水华一般多发生在连续晴朗的天气，而常在阴雨天气崩溃；从水化条件方面来说，该藻水华也常发生于ＮＯ_３－Ｎ浓度以及Ｎ／Ｐ比较大时。在扁藻等绿藻类与海洋原甲藻交替成为优势种时，可以利用水体中Ｃｈl．总量及Ｃｈ１．ｂ、Ｃｈ１．ｃ之间的波动情况来反映该水华的发生与崩溃。This article inquires into variations of the chemical factors before and after Prorocentrum micans water-bloom in seawater experimental enclosures. From this, the folio wing conclusions can be drawn: the waterbloom often breaks out when the weather is fine for a number of days, and crashes when the weather is cloudy or rainy; and it breaks out generally when the concentration of NO_3--N and the ratios of N/P are high. If the dominant species comprise both Chlorophyla and Prorocent- rum micans, we can use the concentration of total Chll. and Chl. c /Chl. b to detect the outbreak or collapsing of this water-bloom.
