连云港海州湾赤潮监控区一次多纹膝沟藻赤潮分析

本文通过2004年09月29日连云港海州湾赤潮监控区发生赤潮的调查监测,对本次赤潮的赤潮生物,及其与各个环境要素进行了相关分析。本次赤潮生物多纹膝沟藻(Gonyaulax polygramma),赤潮生物的数量与表层水体中DO、pH、COD、叶绿素a、活性磷酸盐等呈很好的正相关,与无机氮呈负相关,无机氮是本次赤潮的营养限制因子。

A Lienyungang Haizhou red tide monitoring area more than grain knee ditch algae red tide analysis

This article 9yue29 Japan the Lienyungang Haizhou red tide monitoring area has the red tide investigation monitor through 2004, to this red tide red tide biology, and has carried on the correlation analysis with each environment essential factor. This red tide biology multi-grain knee ditch algae (Gonyaulax polygramma), red tide biology quantity and in the surface layer water body DO, pH, COD, chlorophyll a, the active phosphate and so on assume the very good correlation, assumes the inverse correlation with the inorganic nitrogen,the inorganic nitrogen is this red tide nutrition limit factor.
