Abstract: Since lake eut rophication was first taken into consideration , scientists had managed to simulate the appearance of lake eut rophication , predict the response of lakes to different management through mathematical models , thereby determining the propermeans for management . In general , three developing phases of models of lake eut rophication have been arisen : (1) Single limited factor models , such as the phosphorus model. (2) Models of multiple limited factors , such as models for predicting the primary production of phytoplankton. (3) Eco2dynamic models , which are the main developing t rend of lake models at present and for the future. With improvement of understanding of lake ecosystems and the development of computers , the coupled ecological and hydrodynamic model , the object-oriented model and the neural network model show promise.
