PRELIMINARY OBSERVATIONS OF ALGAL GROWTH AND LAKE EUTROPHICATION IN JINGBO LAKE
镜泊湖藻类生长和湖泊富营养化预测初探

After analyzing the main factors which affect algae growth in Jingbo Lake, a modelfor algae growth was constructed and the algal growth and eutrophication was predicted usinglaboratory and field data. In the algal growing season, N was not a main limiting factor in thelake. In July and August, P was the main limitation. In May, June, September and October,both P and temperature became limiting for algal growth. But with the increasing of P concentration, temperature became the main limitation, which played an adverse role in lake eutrophication. The model testing indicates that output of the model was able to reasonably reflect theregularity of algal growth in Jingbo Lake.
