Modelling the linkage between physical habitat and aquatic organisms on multiple spatial scales has become an important tool in the management of rivers. The mesoscale (10⁰–10² m) represents an intermediate resolution in modelling that bridges the gap between available resources and conservation efforts for riverine species. However, existing mesohabitat classification schemes for lotic systems vary significantly in the definition of habitat types as well as in their application in the field. This article aims to provide an overview of current attempts to model the mesoscale pattern of physical habitats with a focus on fish. First, we outline descriptive, qualitative as well as objective, quantitative classification methods that are available in the literature. Next, the ecological relevance of the mesohabitat concept is being discussed, using single‐species and community‐level approaches as examples. Different modelling approaches that describe and quantify riverine mesohabitats are presented, and finally, limitations and uncertainties in the modelling process are discussed, followed by an outline of future perspectives in mesohabitat modelling.

鱼类生态系统中生境建模：全球综合

在多个空间尺度上模拟自然栖息地与水生生物之间的联系已成为河流管理中的重要工具。中尺度（10 ⁰ –10 ² m）代表建模中的中间分辨率，可弥补可用资源与河流物种保护工作之间的差距。但是，现有的针对抽水系统的中栖动物分类方案在生境类型的定义及其在野外的应用方面差异很大。本文旨在概述当前尝试以鱼类为中心的物理生境中尺度模式的尝试。首先，我们概述了文献中可用的描述性，定性以及客观的定量分类方法。接下来，将以单一物种和社区一级的方法为例，讨论中生境概念的生态相关性。介绍了描述和量化河流中生境的不同建模方法，最后，
