Qiandaohu lake was very famous for its clean water quality . but in recent years the water body has become seriously eutrophic especially during summer months in some areas of the lake and came to the attention of national , provincial and city environment protection agency . the main objective of this study involved the following : sampling and monitoring water from the lake ; water quality assessment and biological assessment ; ascertain the limiting factors for phytoplankton growth ; fuzzy cluster analyse of water pollution of all sampling points ; predicting total phosphorus concentration in the lake by using static models ; setting up regression models and their application ; setting up an eco - dynamic model and its simulation 本研究根據1998 - 2000年連續監測數據,對千島湖進行了水質評價和生物評價;分析了千島湖水體富營養化的限制性因子;同時根據千島湖各個取樣點的污染狀況,對千島湖進行水環境質量區劃;利用前人的經驗統計模型預測了千島湖現有的磷濃度水平及治理所需要削減的污染物負荷量;并且組建了多個回歸統計模型,運用這些模型預測千島湖水體中的總磷濃度;最后根據多年水質、底質、生物等方面的監測數據以及千島湖流域的氣象和社會經濟狀況的資料組建機理性的千島湖富營養化模擬模型。

Only the water at jiekou had been eutrophic . the result of biological assessment was that the average density of phytoplankton at all the sampling spots was more than 1 , 000 , 000 per litre , indicating that the lake was eutrophic going by the population density . but this density of phytoplankton was higher than that in similar lakes at the same pollution level 生物評價結果認為,千島湖浮游藻類平均密度較同類營養水平的淡水水體高,其所有取樣點浮游藻類平均密度都10 ~ 6個? l ,國內外一般認為當浮游植物平均密度10 ~ 6個? l時,其已經達到富營養化水平,因此單從浮游植物密度來看,可以認為千島湖已達到水體富營養化。
