模型可以被认为是关于系统的知识要素的综合。因此，模型的质量在很大程度上取决于我们对元素和可用数据的了解的质量。如果我们对给定问题的知识和数据很差，就不能指望系统的模型能够填补我们详细知识中的漏洞，或者修复一组糟糕的数据。另一方面，模型能够提供关于整个系统的反应和性质的新知识。模型代表了知识和数据的综合，因此可以提供结果，特别是关于系统属性的结果。此外，当我们把涵盖不同观点的许多不同模型的结果放在一起时，我们就得到了一个更全面的生态系统整体图景，因为我们可以像第一章和第二章中讨论的那样，通过使用多元化的观点来完全覆盖我们的观察。在我们努力实现最佳的这种观点时，建模是一个非常有用的工具。
A model can be considered as a synthesis of elements of knowledge about a system. The quality of the model is therefore very dependent on the quality of our knowledge about the elements and the available data. If our knowledge and data of a given problem are poor, it mustnotbe expected that the model of the system will be able to fill the holes in our detailed knowledge or repair a poor set of data. On the other hand, models are able to provide new knowledge about the reactions and properties of an entire system. A model represents a synthesis of knowledge and data and can consequently provide results particularly about system properties. Furthermore, when we put together the results of many different models covering different viewpoints, we obtain a more comprehensive overall picture of the ecosystem, because we can, as discussed in Chapters 1 and 2, only cover our observations completely by the use of a pluralistic view. Modelling is a very useful tool in our effort to achieve the best possible such view.
