文摘According to environmental data,Ecopath with Ecosim (EWE) model can quantitatively describe the energy flow in the production and consumption of function components of system by using trophodynamics,and accurately assess the biomass and stable state of aquatic ecosystem.In the paper,the basic principle and parameters of EWE model were introduced firstly,and the relationship between Q/B (the important parameter of EWE model) and basic life indices of fish was discussed,then the current study and typical results of EWE model were analysed,finally the related parameters of EWE model in Caohai Nature Reserve were analysed.
