摘 要: 于2009年4月、5月对抚河河口及下游分流处浮游生物进行调查。结果表明:1) 分流处(礁石坝)共检测出浮游藻类62种,分列于4门,37属,绿藻(Chlorophyta)、硅藻(Bacillariophyta)、蓝藻(Cyanophyta)为优势种群;共检测出浮游动物33种,轮虫类(Rotifera)、枝角类(Cladocera)在数量上占较大比例。2) 东支河口(青岚湖)共检出浮游藻类6门,45属,共80种,绿藻、硅藻、蓝藻为优势种群;共检测出浮游动物�27种�,轮虫和枝角类为优势种群。3) 西支河口(金溪湖)共检出浮游藻类7门,52属100种,绿藻、硅藻、蓝藻为优势种群;共检测出浮游动物31种,其中轮虫和枝角类为优势种群。4) 浮游生物密度在分流处为�6.33×�10�5个/mL,东支河口为7.67×10�5个/mL,西支河口为9.50×10�5个/mL. 与下游分流处相比,河口浮游生物密度激增,主要是蓝藻、绿藻、硅藻三大门类的浮游植物和轮虫、枝角类等浮游动物的大量繁殖。�

Abstract: This paper made a two-month investigation about the plankton of Fuhe river estuary and the lower reaches forks from April to May of 2009. The results showed: 1) A total of 62 species of phytoplankton was detected in Jiaoshi dam, followed in 4 Phyla and 37 Genera. Green algae, diatom and blue-green algae were dominant populations. Detected zooplanktons included a total of 33 species, and the dominant populations are Rotifera and Cladocera. 2) There was a wide variety of plankton in Fuhe river estuary. East branch estuary-Qinglan lake was detected with a total of 80 species phytoplankton in 6 Phyla and 45 Genera. Green algae, diatom and blue-green algae are dominant populations. Detected zooplankton included a total of 27 species, and dominant populations, the same as Jiaoshi dam, were Rotifera and Cladocera. 3) West branch estuary-Jinxi lake was detected with a total of 100 species phytoplankton in 7 Phyla and 52 Genera. Green algae, diatom and blue-green algae were dominant populations. Detected zooplankton included a total of 31 species, and the dominant populations, the same as Jiaoshi dam, were Rotifera and Cladocera. 4) Plankton density at the lower reaches forks, the East branch estuary and the west branch estuary were 6.33×10�5/mL, �7.67×10�5/mL� and 9.50×10�5/mL respectively. �
