福建湄洲湾浮游植物的分布

本文根据1984年福建海岸带调查及1988年港湾志调查所获的样品资料,分析报道了湄洲湾海域浮游植物的种类组成、数量时空分布及其影响因子,文中共鉴定浮游植物127种,细胞总量分布为5月出现主高峰,8月为次高峰,2月为最低谷,其数量分布和季节变化与水温、盐度、海流和季风的影响密切相关。

Distribution of phytoplankton in Meizhou Bay, Fujian

An ecological study was made on the composition and distribution of phytoplankton in the Meizhou Bay, Fujian province. Among 127 species, there are 2 blue algae, 104 diatoms and 21 pyrrophyta. There are 14 dominate species: Asterionella japonica, Biddulphia sinensis, Chaetoceros decipiens, Coscinodiscus oculus-iridis, Nitzschia paradoxa , Nitz. pungens, Rhizosolenia styliformis, Skeletonema costatum, Thalassionema nitzschioides, Thalassiothrix frauenfeldii, Ceratium furca, Cer. fusus, Cer. trichoceros, and Noctiluca scintillans. The ecological groups are as follows: Eurytopic species 49%, warm water 44% and temperate species 7%. Seasonal variation in the total number of phytoplankton shows two annul peaks in the area, A major peak in May and the secondary peak in August, with the lowest value in February. The effects of temperature, salinity, currents and monsoon on the numerical distribution and seasonal variation of phytoplankton are discussed.
