摘要
于1979～2005年调查了大伙房水库理化指标、水生生物群落、藻类叶绿素a、初级生产力,对水质安全预警进行了系统研究。结果表明,水库水质安全预警,总磷为轻-中警,总氮为轻-重警,生态综合预警为轻-中警。大伙房水库水体只受到轻度污染,水质等级为近Ⅱ级,属浮游植物响应型中营养水体。
The paper studies the water quality safe early warning of Dahuofang reservoir. The result indicates that total phosphorus is light-medium warning, total nitrogen is light-weight warning, ecological comprehensive early warning is light-medium warning. The degree of water pollution in Dahuofang reservoir is light. The grade of water quality is close to II class, belongs to medium nutrition water body.
