摘要
利用1991年至1997年对太湖梅梁湾的定点监测资料和1997年8月对西太湖北部的三次水化学和藻类布点监测资料，初步探讨了西太湖北部夏季藻类分布和种间关系．结果显示，西太湖北部夏季藻类主要由蓝藻、隐藻、硅藻、绿藻、裸藻和甲藻六大门类组成，以微囊藻为优势种的蓝藻水华主要在夏秋季暴发，夏季梅梁湾内藻类光合效率较高是该地区蓝藻暴发的原因之一；自梅梁湾河口湖区向外太湖，藻类总生物量递减，且种类组成也发生变化；藻类种间关系主要体现在同属种类显著正相关．
This study is dealing with the summer phytoplankton species composition in northern part of west Taihu Lake by using the monitoring data from 1991 to 1997 and the three-time monitoring chemistry data and phytoplankton data in August 1997. The results show that there are 6 main phytoplankton groups in northern part of west Taihu Lake, which are Cyanophyta, Cryptophyta, Bacillariophyta, Chlorophyta,Euglenophyta and Pyrrophyta. One reason that Microcystis spp. forming water bloom occurs every summer might be that the phytoplankton P/B ratio is higher in the Meiliang Bay. From the north part to the south part of the Meiliang Bay, the total phytoplankton biomass reduced clearly. The results also show that there is no big difference among algal species composition except that there are positive liner correlation among species in the same genus.
