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 ...
