摘　　要：利用淮安市环境监测中心站1998年—2000年洪泽湖水质监测资料,以洪泽湖水体最能表征营养化状态进程的叶绿素a为基准因子,分析了洪泽湖水质富营养化的原因。通过QBASIC多元逐步回归分析,得出洪泽湖水质富营养化的主控因子是悬浮物、透明度,总磷是富营养化的潜在限制性营养盐。From the monitoring materials of water quality of the Lake of Hongze from 1998 to 2000 analyzed by Huaian Environmental Monitoring Center, the reasons of eutrophication of the Lake of Hongze was studied, chlorophyll a as reference factor which can best reflect the state of eutrophication. After QBASIC multiple regression, the key factors of water's eutrophication of the Lake of Hongze was determined, they were suspended substance and transparency. The potential limiting nutrient salt of eutrophication was TP.
