摘要:
2016 年对常熟市重要饮用水源地尚湖开展了4 个季度的浮游植物监测与分析，结果表明：4 个季节采样定量检测到尚湖浮游植物8 门79 属141 种，其中绿藻（56 种）、蓝藻（33 种）和硅藻（32 种）为物种数较多的门类，主要优势种属有水华束丝藻、肘状针杆藻、梅尼小环藻、颗粒直链藻、狭细颤藻、极细微曲壳藻等；全湖藻类密度与生物量大小按季节排序均为夏季＞冬季＞秋季＞春季；尚湖不同湖区浮游植物群落结构的关键影响因子存在差异，DO、TN和SD 对于取水口所在的东南半湖浮游植物群落结构变化有关键的影响作用，在西
Abstract:
In 2016, four seasons of phytoplankton monitoring and analysis were carried out in Shang Lake,which was an important drinking water source in Changshu City.The results showed that there were 141 species belonging to 79 genera of 8 phytoplankton species in four seasons, mainly including 56 species of green algae, 33 species of cyanobacteria and 32 species of diatoms.The main dominant species were aphanizomenon flosaquae, synedra ulna, cyclotella meneghiniana, melosira granulata (Ehr.) Ralfs., etc.The density and biomass of the whole lake sorted by season were summer ＞ winter ＞ autumn ＞ spring.There were differences in the key impact factors of phytoplankton community structure in different lake areas of Shang Lake.DO, TN and SD played a key role in the structural changes of phytoplankton community in the southeastern half of the lake,while TP and NH3-N played a more important role on the phytoplankton community in the northwestern half of the lake.
