| 中文摘要 |
| 1996-1997年对密云水库库区水体和流域内水环境状况的初步调查表明:库区水体的营养程度为中营养型;浮游藻类的群落结构为绿藻(Chlorophyta)-硅藻(Bachilariophyta)型;湖泊的营养特征为浮游植物响应型,水质尚好。但水体中TN、TP含量已分别达到1.21mg·L-1和0.025mg·L-1,浮游藻类细胞密度已达到3417 Cels·ml-1.水质有明显的向富营养化发展的趋势。对库区水体营养盐类增长的原因作了分析,并提出了保护水资源的措施。 |
| 英文摘要 |
| Miyun reservoir is an main source of water that supplying potable water for Beijing.The research in 1996-1997 indicates that nutrition level of the water body belongs to middle nutrition type;Community structure of the planktonic algae belongs to green algae-diatom type;Nutrition characteristic of the water body belongs to responding type of planktonic algae.The water quality is still better.But the density of planktonic algae,the content of total nitrogen and total phosphorus are rising,the water body tends to be of eutrophication. |
