本文综合了几条论据，认为一个生态水文学框架，即生态水文学框架，即LABORATIONAL、fiELD和侧重于生物群的水文控制的理论方法，对我们理解河网作为生态廊道的功能有很大的贡献。这些功能被证明与：物种的空间生态学；种群动态和生物入侵；水媒疾病的传播有关。作为例子，我们描述了对密西西比-密苏里盆地fish多样性格局的集合群落预测，fl冲积景观对物种丰富度海拔梯度的地貌控制，同一密西西比-密苏里河水系的斑马贻贝入侵，以及鲑鱼fish增殖性肾脏疾病的传播。我们认为，fl河流景观中生态过程的空间描述，受其特定的水文和生态动力学以及相互作用的生态系统矩阵的限制，即嵌入在fl河流和寄主/病原体移动网络中的定向扩散，已经产生了非常广泛的重要结果。因此，在作者看来，值得注意的科学和实践观点对生态水文学研究的未来发展持开放态度。
This paper draws together several lines of argument to suggest that an ecohydrological framework, i.e. la- boratory, fi eld and theoretical approaches focused on hydrologic controls on biota, has contributed substantially to our understanding of the function of river networks as ecological corridors. Such function proves relevant to: the spatial ecology of species; population dynamics and biological invasions; the spread of waterborne disease. As examples, we describe metacommunity predictions of fi sh diversity patterns in the Mississippi – Missouri basin, geomorphic controls imposed by the fl uvial landscape on elevational gradients of species ’ richness, the zebra mussel invasion of the same Mississippi – Missouri river system, and the spread of proliferative kidney disease in salmonid fi sh. We conclude that spatial descriptions of ecological processes in the fl uvial landscape, constrained by their speci fi c hydrologic and ecological dynamics and by the ecosystem matrix for interactions, i.e. the directional dispersal embedded in fl uvial and host/pathogen mobility networks, have already produced a remarkably broad range of signi fi cant results. Notable scienti fi c and practical perspectives are thus open, in the authors ’ view, to future developments in ecohydrologic research.
