摘　　要：基于环境调查数据,EWE生态营养通道模型利用营养动力学原理,定量描述系统中各功能成分生产和消耗的能量流动,能较为准确地评估稳定状态下水域生态系统组份的生物量及其系统稳定状态。首先概括了EWE模型的基本原理和基本参数,然后探讨了EWE重要参数Q/B与鱼类基本生命指标之间的关系,最后分析了EWE模型的研究现状及典型研究成果。According to environmental data,Ecopath with Ecosim（EWE） 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,then the relationship between Q/B（the important parameter of EWE model） and basic life indies of fish was discussed,and the current study and typical results of EWE model were analyzed finally.
