Ecopath与Ecosim（EwE）建模方法将生态系统营养物质平衡分析（Ecopath）软件与动态建模能力（Ecosim）相结合，用于探索捕捞和环境干扰的过去和未来影响，以及探索最佳捕捞政策。生态模拟模型可以在空间地图网格（生态空间）上复制，以便探讨海洋保护区等政策，同时考虑空间扩散/平流效应，生态路径方法和软件已经开发了20年，生态模拟模型于1995年出现，生态空间于1998年出现，形成了一个综合和广泛应用的软件包。我们提出了一个概述的Ecopath，Ecosim和Ecospace模块的计算方面，因为它们是在最新的软件版本中实现的。本文总结了模拟系统的能力，评估渔业和环境如何影响生态系统。最后，我们对使用该软件进行政策探索的陷阱提出警告。(C)2003 Elsevier B.

The Ecopath with Ecosim (EwE) modeling approach combines software for ecosystem trophic mass balance analysis (Ecopath), with a dynamic modeling capability (Ecosim) for exploring past and future impacts of fishing and environmental disturbances as well as for exploring optimal fishing policies. Ecosim models can be replicated over a spatial map grid (Ecospace) to allow exploration of policies such as marine protected areas, while accounting for spatial dispersal/advection effects.The Ecopath approach and software has been under development for two decades, with Ecosim emerging in 1995, and Ecospace in 1998, leading to an integrated and widely applied package. We present an overview of the computational aspects of the Ecopath, Ecosim and Ecospace modules as they are implemented in the most recent software version. The paper summarizes the capabilities of the modeling system with respect to evaluating how fisheries and the environment impact ecosystems. We conclude by a warning about pitfalls in the use of the software for policy exploration. (C) 2003 Elsevier B.V. All rights reserved.
