Advance in study of lake eutrophication models

Abstract

Since lake eutrophication was first taken into consideration, scientists had managed to simulate the appearance of lake eutrophication, predict the response of lakes to different management through mathematical models, thereby determining the proper means for management. In general, three developing phases of models of ake eutrophication 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)Eco-dynamic models, which are the main developing trend 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.
