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。
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 eutrophication level by analysis on spatial-temporal distribution of phytoplankton and involved factors. Finally,reason for first blue-green algae bloom in Hongze Lake was discussed.
