【摘要】 本文根据深圳海域1981-2002年发生的93起赤潮记录,分析了深圳海域赤潮发生的3点特征:①深圳海域的赤潮多发区位于大鹏湾、大亚湾和深圳湾,其中大鹏湾的盐田水域、大亚湾西部的东山和坝光水域、深圳湾的后海与东角头水域为赤潮多发地段;②赤潮发生的频率增高,赤潮持续时间延长;③全年中有两个赤潮多发季节,主要集中在3-5月,其次为9-11月。同时,通过研究深圳海域赤潮的原因生物,得出:赤潮原因生物丰富,约有39种,其中甲藻最多,其次为硅藻,具有一定的区域分布特征及明显的演替规律,不断有新的生物种类引发赤潮。更多还原

【Abstract】 Total 93 red tides events were recorded in this paper from 1981 to 2002 in Shenzhen coastal waters. During the 22 years, there are three characters of the red tides: 1) The red tide events were caused more in Dapeng Bay, Daya Bay and Shenzhen Bay. 2)The frequency of red tide events increased, and the duration of them extended. 3) There were two seasons during which the red tide events take place more frequently the first season was from March to May, the second one was from September to November. Otherwise, there are two characters of the red tide causative organisms: 1) The diversity of red tide causative organisms increased, about 36 species were recored. 2) It seemed that there’s an obvious trend on the succession of red tide causative organisms, and there were frequently new species causing red tide events.更多还原
