| 摘 要： | 为探明天津市河流、水库浮游植物群落结构及其与环境因子的关系,于2009年5月、7月、9月对天津市的5条河流和4个水库进行采样分析。结果表明,天津市河流浮游植物为7门100种,优势种为绿藻、蓝藻;水库为8门81种,优势种为硅藻、蓝藻。环境因子在河流和水库间差异极显著的为透明度、pH、总磷和重碳酸盐碱度(P<0.01)。影响浮游植物群落结构的环境因子,河流依次为:浮游动物丰度、高锰酸盐指数、氨氮、碳酸盐碱度、磷酸盐浓度、总磷;水库依次为:重碳酸盐碱度、钙离子浓度、氨氮、透明度、溶解氧、水深、叶绿素(a、b)、总碱度、总硬度、pH。

| Abstract: | Sampling survey on 5 rivers and 4 reservoirs in Tianjin were carried out in May,July and September 2009 to study the relationship between phytoplankton community and environment factors of rivers and reservoirs in Tianjin.The result showed that there' were 100 species,7 phylum phytoplankton in rivers,while 81 species,8 phylum phytoplankton in reservoirs.Dominant species were Chlorophyta and Cyanophyta in rivers,Bacillariophyta and Cyanophyta in reservoirs.Secchi-depth(SD),pH,total phosphorus(TP),bicarbonate alkalinity(Bi-alk) were significant different between rivers and reserviors(P<0.01).Environmental factors which affected phytoplankton density in rivers were:Zooplankton abundance(Zoo),potassium permanganate index(COD),ammonianitrogen(NH3-N),carbonate alkalinity(Ca-alk),phosphate concentrations(PO43-),TP inturn.Those affected phytoplankton in reserviors were:Bi-alk,Ca2+,NH3-N,SD,dissolved oxygen(DO),water depth(H),chlorophyll(a,b),total alkalinity(alk),total hardness(DH),pH in turn. |
