| Abstract | Nutrient sources and loading of Dianchi Lake have been studied based on available
data. A VOLLENWEIDER chart and the OECD boundary value of classification of lakes
have been applied to assess the eutrophic state of Dianchi Lake. As a consequence of the
morphometric and loading conditions, the north part or the Internal Lake is hypertrophic,
while the south part, the Outer Lake is eutrophic.
An eutrophication model is set up to assess the eutrophication condition and evaluate
restoration methods. Reduction of external nutrient input is not enough to alleviate the
hypereutrophic state in the Internal Lake. In-lake control measures must be implemented
in the Internal Lake. The most feasible in-lake control measure is harvesting of water
hyacinths. Routine control measure must be undertaken to remove nutrients and toxic
substances in the sediment. |
