摘要
对输水沿线水域水生生物作了调查,进行了氮、磷营养盐对浮游藻类增殖影响的室内及现场生态模拟试验,预测棘洪滩蓄水库可能发生富营养化的内外因素。结果表明,蓄水库蓄水后年内氮浓度为0.28mg/L,总磷浓度为0.021mg/L,达中营养型水平。5年内可能达中一富营养型。2000年存在由微囊藻形成的富营养化的危险性。
The aquatic plants in the diverting water course from Yellow River to Qingdao City were investigated and the effects of nitrogen and phosphorus on the growth of the algae were studied both in field and in laboratory. The possible eutrophication of Jihongtan Reservoir was predicated before the completion of the project. The results showed that the reservoir will be at mesoeutrophic state within a period of five years, and reach mesoeutrophication after that. The danger of eutrophication is possible after 2000.
