湖泊水库结构生态动态模型

综述了湖泊水库结构生态动态模型的研究进展及其在湖泊水库环境生态模拟中的应用。结果表明,热力学理论为获取湖泊水库生态系统的特性提供了一条整体性的途径,热力学概念“Ｙｏｎｇ”可将生态学理论（达尔文理论）和热力学理论（最大Ｙｏｎｇ原理）很好地联系起来。引入Ｙｏｎｇ后,许多重要模型参数的目标函数可根据最大Ｙｏｎｇ原理获得,达尔文“达者生存”理论可被定量为一个生态约束条件用于发展湖泊水库结构生态结构模型,从

Structural ecodynamic model for lakes and reservoirs

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 some important model parameters is obtained according to the maximum exergy principle,and Darwin's theory "survival of the fittest"can be quantified as an ecological constraint to develop the structural ecodynamic model for lakes and reservoirs,which makes the proposed model ecologically more reasonable and practically more flexible.However,in order to use effectively exergy in ecological modelling and environmental management of lakes and reservoirs,the camination and optimization of exergy are still needed to discuss and study further.
