福建省自然科学基金(D0210003);; 厦门大学科技创新项目(XDKJCX20041018)资助 对深圳福田红树林保护区浮游植物群落结构和季节变化进行研究.共鉴定到浮游植物5门25属75种,其中硅藻门21属68种,蓝藻门1属1种,甲藻门1属1种,绿藻门1属3种,裸藻门1属3种.密度的季节变化范围为1.0×106～5.0×106个/L,平均密度为2.7×106个/L.赤潮藻和耐污染特征的种类如威氏海链藻和微小小环藻等是浮游植物的主要成分.底栖性、附着性和淡水性的种类在浮游植物中经常出现.与以前的研究比较,福田红树林区水体浮游植物群落朝着种类个体变小、种类数减少、密度增加、耐污染种类增加的方向变化,这反映了该红树林区水体富营养化程度高,水质持续恶化. 【英文摘要】 Seasonal changes and ecology of phytoplankton in mangrove reserves in Futian,Shenzhen were studied.Totally 75 species belonging to 25 genera in 5 phyta were identified,among which 68 taxa in 21 genera belonged to Bacillariophyta,1 taxa in 1 genera for Cyanophyta and Pyrrophyta,and 3 taxa in 1 genera for Euglenophyta and Chlorophyta,respectively.Density varied from 1.0×106 to 5.0×106 ind./L,and average density was 2.7×106 ind./L.Redtide causive species and pollution-tolerance species such as Thalassiosira we...
