闹得海水库营养状态分析及富营养化防治

结合9年来对闹得海水库水质监测及相关文献资料，评价闹得海水库营养状态，分析主要污染物变化趋势，对该水库营养状态进行分析，提出该水库富营养化防治对策。结果表明：闹得海水库9年来营养状态在中营养-中富营养之间，主要营养盐总氮、总磷及高锰酸盐指数9年间无显著变化，农业面源是该水库主要营养盐及有机物主要来源。

Analysis of Trophic State of Water Body in Naodehai Reservoir and Prevention of Eutropher

Combined with water quality monitoring data obtained during resent 9 years and related documents, the trophic state of water body in NaoDehal reservoir and tendency of main pollutants were observed, further countermeasures against eutrophication were put forward. The monitoring data shows that there is no obvious fluctuation of water quality in past 9 years, in addition its eutrophication level has been on the base of mesotrepher and middle eutrepher, on the other hand as the loads of main pollution contents, for instance total nitrogen, total phosphorous, permanganate index and so on were not shown remarkable changes and agriculture was pointed out as a area source of eutrophic and organic matters.
