| 摘 要： | 由于淀山湖上游污染负荷以及周边污水的排放,淀山湖已经严重富营养化。通过建立淀山湖生态系统模型,基于大量现场实测数据,对生态系统模型进行率定和验证,并利用生态系统模型对淀山湖N,P营养盐时间变化规律和藻类生长演替进行了系统研究,对各污染负荷削减的富营养化控制方案的效果进行模拟。模拟结果显示:该生态模型较好地模拟了常规水质和藻类的动态变化;淀山湖污染负荷主要来自于上游负荷,削减上游负荷对水质改善效果明显好于其他污染源削减方案;削减上游负荷95%以上,才能有效抑制蓝藻水华;P对蓝藻生长的控制效果好于控制氮。

| Abstract: | Dianshan Lake has become hyper-eutrophication because of the inflows and sewage discharges into the lake.Based on the systematic observations of hydrology,water quality and biology,as well as experimental data,the ecosystem model had been built up to simulate the temporal distribution of nutrients and the seasonal succession of algae in Dianshan Lake.The ecosystem model was calibrated and validated by the observations and historical data.The effect of eutrophication control measures on water quality in Dian... |
