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。
In this paper, we studied the changes of hydration conditions before and after the marine meiofauna blooms in the mariculture ponds. The following results were obtained: Primula algal blooms usually occur in continuous sunny weather, Rainy weather collapses; in terms of hydration conditions, algal blooms often occur when NO3-N concentration and N / P ratio are relatively large. In the algae and other green algae Penaeus algae and alternate alternate dominant species, you can use Chl in water. Total and Ch1. b, Ch1. c between the fluctuations to reflect the occurrence and collapse of the bloom.
