This paper reviews the researches on the structural ecodynamic models for lakes and reservoirs and their applications in ecological modelling of lake and reservoir environment .The results follow that the thermodynamic theories provide a holistic approach for capturing the properties of lake and reservoir ecosystem ,the thermodynamic concept“exergy” links well the ecological theory(Darwin's theory)with thermodynamic theory(the maximum exergy principle).By the application of exergy,a goal function of s...
