摘要
2000年丰水期和枯水期对广东大中型水库的磷污染和富营养化现状进行了调查。结果表明,在调查的20个大中型供水水库中,一半以上的水库受到磷污染,磷污染已成为水库富营养化的重要原因。水库的总磷浓度与水库的营养状态基本一致。水库普遍存在磷限制现象,且枯水期的磷限制现象更为严重。在低温和磷限制条件下,硅藻比绿藻更加有优势。
Investigation and monitoring on phosphorus pollution and eutrophication status of the large and medium reservoirs for water supply in Guangdong province were carried out in flood season and dry season of 2000. Among the 20 investigated reservoirs, half have been contaminated by phosphorus. So phosphorus pollution was one of the important causes that involved in eutrophication. The concentration of TP was consistent with the trophic state of the reservoirs. Phosphorus limitation phenomenon was common in the reservoirs, and it was more obvious in the dry season. Under low temperature and phosphorus limitation diatoms had more advantage than green algae.
