Based on the basic ecological model proposed by Jorgensen and the species composition of lake ecosystem, a new approach to calculate the growth rate of phytoplankton weighted growth rate method was presented. The thermodynamic concept “Exergy” was also introduced into the ecodynamic model for lakes,and the changes in the species composition and the ecological structure of lake ecosystem were reflected by the changing exergy.An improved ecodynamic model for lakes was developed by combining the weighted growth rate with the application of exergy. These improvements comprehensively take the ecological properties of lake ecosystems into account, making the ecodynamic model ecologically more reasonable and practically more flexible. The applications of the improved ecodynamic model in the ecological modelling and prediction of Dianchi Lake, have demonstrated that this model is practicable and satisfactory.
