摘    要:2004年9月 ̄2005年3月长江江苏段枯、平、丰3个水期的浮游植物的采集调查,共检出长江江苏段浮游植物10门96属168种(包括未定种),其中绿藻门64种,占38.10%;硅藻门58种,占34.52%;蓝藻门25种,占14.88%;裸藻门8种,占4.76%;黄藻门5种,占2.98%;金藻门3种,占1.79%;甲藻门2种,占1.19%;红藻门、隐藻门和轮藻门各1种,占0.60%。丰水期浮游植物优势群为直链藻(Melosira)、颤藻(Oscilatoria)、脆杆藻(Fragilaria)和纤维藻(Ankistrodesmus);平水期优势群为直链藻(Melosira)、颤藻(Oscilatoria)、脆杆藻(Fragilaria)、微孢藻(Microspora)和圆筛藻(Coscinodiscus);枯水期优势群为星杆藻(Asteri-onella.)、新月藻(Closterium)、直链藻(Melosira)和脆杆藻(Fragilaria)。各江段浮游密度都以枯水期最高,基本以丰水期为最低。

Abstract:During the high-water period?middling-water period?low-water period of the Yangtze River in the Jiangsu section from September in 2004 to March in 2005 , 168 species(including undetermined species), 96 genus, 10 phylum phytoplankton were checked out. The phylum Chlorophyta contained 64 species,accounting for 38.10%; Bacillariophyta contained 58 species,accounting for 34.52%;Cyanophyta contained 25 species,accounting for 14.88%;Euglenophyta contains 8 species,accounting for 4.76%;Xanthophyta contained 5 species,accounting for 2.98%;Chrysophyta contained pecies,accounting for 1.79%;Pyrrophyta contained 2 species,accounting for 1.19%; Rhodophyta?Cryptophyta and Charophyta contained 1 species,respectively,accounting for 0.60%. The dominant genus were Melosira?Oscilatoria?Fragilaria and Ankistrodesmus in the high-water period; Melosira?Oscilatoria?Fragilaria?Microspora and Coscinodiscus in the middling-water period;and Asterionella? Closterium?Melosira and Fragilaria in the low-water period. The density of phytoplankton was maximal in the low-water period in each segment , and minimal in the high-water period .
Keywords:Yangtze River  Jiangsu  phytoplankton  algae  hydrobiont
