Eutrophication parameters,which were determinated by conventional analytical methods,included algae number, chlorophyll-a (Chl-a),total phosphor (TP),total nitrogen (TN),COD,TOC,Fe,turbidity and water temperature.

• 富营养化的有关指标藻细胞数、叶绿素-a(Chl-a)、总磷(TP)、总氮(TN)、化学耗氧量(COD)、总有机体(TOC)、铁(Fe)和浊度用常规的分析方法,现场测定水温。
