Review on development of Ecopath model and its application in aquatic ecosystems
Ecopath模型在水生态系统评价与管理中的应用

Ecosystem model is an important way to study food web structure and function, and Ecopath is a powerful ecosystem model, by which quantitatively analyze ecosystem structure and function, evaluate and simulate ecosystem development, and propose appropriate management. We gave a brief introduction of Ecopath approach advancement and development, summarized the methods applications in domestic and international aquatic ecosystems research and management, and analyzed the existed problem in the process of its application. If the research about biological population dynamics and diet composition was lack in the ecosystem, which would lead to be difficult to get the feeding data needed in the model, to decrease the accuracy of the P/B, Q/B input parameters calculation. It will be focused on the sensitivity analysis, uncertainty analysis of input parameter and evaluation of the Ecopath model simulation in the future development and application.
