| 摘 要： | 于2001年10月和2002年4月两次调查分析了高位池、低位池两种类型的南美白对虾养殖池的理化因子及浮游植物群落的特征.结果表明:低位池的营养盐浓度普遍高于高位池,而高位虾池的盐度则高于低位.盐度是影响两类虾池浮游植物群落特征的主要因素.盐度较小(<5)的养殖池中,蓝藻占优势,主要为微囊藻、平裂藻、水花束丝藻、色球藻等;盐度介于10～30的池中,硅藻占优势,主要为舟形藻、桥弯藻等.

| Abstract: | The phytoplankton communities and physical and chemical factors in two types, upland pond and lowland pond, of Penaeus vannamei culture ponds were investigated. The results showed that the nutrient contents of lowland ponds were higher than that of upland ponds. Water salinity of upland ponds was higher than that of lowland ponds. Salinity may be the main factor that influenced the phytoplankton communities. Cyanophyta, such as Microcystis sp., Merismopedia glauca and Aphanizomenon flosaquae, predominated numerically in low salinity ponds, while Diatom such as Navicula cryptocephala and Asterionella formosa in high salinity ponds. |
