摘    要:为了掌握苏州城市河道景观水体藻类富集、消长规律,为制订河道水环境质量改善方案提供科学依据,于2004年5~12月对苏州苗家河试验区进行了水质状况以及浮游植物种类和数量的调查研究。试验区河道共检出浮游植物6门73属,通过对数量进行比较,明确了苏州城市河道以绿藻-硅藻为优势种的浮游植物分布特征。通过对不同季节水体叶绿素a含量、浮游植物生物量和数量进行分析,发现浮游植物变化呈现出夏季>秋季>春季>冬季的季节规律。这一变化结果初步揭示了河网地区城市滞流污染河道水体中浮游植物的种群分布和季节上的消长规律,可为水环境质量改善与生态修复提供重要参考。

关 键 词:浮游植物  城市河道  滞流水体  消长规律

Abstract:In order to understand the growth of phytoplankton in city rivers in Suzhou City,and to provide scientific basis for the improvement of water environment,the water condition and the species composition of phytoplankton were investigated in Miaojia River in Suzhou City from May to December in 2004.Results showed that there were 73 species of phytoplankton belonging to 6 phya,in which scenedesmus and diatom were predominant.Through analyzing Chla.,biomass and population of phytoplankton,the density of phytoplanktons ranged from high to low in the following season order: summer>autumn>spring>winter.This result indicated primarily the water's polluted character and the growth of phytoplankton in network of waterways in city,and it provided important references for water quality improvement and restoration.
Keywords:phytoplankton  city river  lagging water body  growth rule
