摘要
于1987年8月在湛江港设13个点采样。鉴定表明,共有浮游植物37属94种和变种;优势种类有中肋骨条藻、日本星杆藻、佛氏海毛藻等。湛江港浮游植物密度较高,港内外平均达1.3×104cell/L和7.3×105cell/L。经单项营养指数和营养状态结合指数分析表明,除两个点无机氮浓度略超标外,所有站位均未达到富营养化水平。调查期间,共发现赤潮生物31种,其中主要有中肋骨条藻、日本星杯藻、佛氏海毛藻、尖刺菱形藻和夜光藻等,中肋骨条漠和日本星杆藻曾形成水华。
A study on phytoplankton from 13 stations in Zhanjiang Harbour in the westGuangdong coast, South China Sea, was carried out in August, 1987, Ninety fourtaxa were identified in total. Assorted dominant species included Skeletonema costatum, Asterionella japonica, Thalassiothrix frauenfeldii, etc. The mean phytoplankton density was relatively high, 1.3 × 104cell/L and 7.3 ×105cell/L in the innerand outer harbour waters respectively. Analysis of nutrient concentration periodrevealed that the liarbour was mesotrophic. Among the 94 species, 31 were red tidecausative species, including Skeletonema costatum, Nitzschia Pungens, Noctiluca scintillans, etc, Bloom caused by S. costatum and A. iaponica was found during thestudy period.
