摘要:

对洪泽湖及其入湖河流水质现状进行了评价，得知洪泽湖及其入湖河流总体水质为劣V类，影响两者水质的主要污染物为总磷和总氮。对洪泽湖浮游植物的时空分布及相关因子进行分析，得知洪泽湖目前为轻富营养化水平。最后对洪泽湖第一次发生蓝藻聚集现象的原因进行了分析。

Eutrophication Assessment of Water Quality in Hongze Lake

Abstract:

The water quality of Hongze Lake and its into-lake river was assessed as worse than Grade V.The main pollutants were total nitrogen and total phosphorus in the lake.Hongze Lake was at light entrophication level by anlysis on spatial-temporal distribution of phytoplankton and involved factors.Finally,reason for first blue-green algae bloom in Hongze Lake was dicussed.

Key words: water quality phytoplankton eutrophication bule-green algae gathered
