Is ecohydrology one idea or many

摘要: Examples cited by Kundzewicz (2002) to provoke discussion of ecohydrology reveal divergent notions the fundamental nature concept. At issue is answer this question—does term “ecohydrology” refer a single idea or does it encompass many different ideas? Here, I argue that encompasses diverse ideas at interface between hydrology and ecosystem science. Zalewski’s (2000) definition captures competing views ecohydrology, even as attempts reconcile them; “Ecohydrology, study functional interrelationships biota catchment scale, new approach achieving sustainable management water.” First, introduced an area directed toward understanding interdependence hydrological ecological processes. Next, provides single, overarching paradigm for water based on holistic vision water’s role in environment. Can be both these things? Traditional depends information derived from A similarly integrated processes (Fig. 1). However, science alone not determine management. Other factors, besides scientific knowledge, combine overall Therefore, either management, interaction It cannot both. suggest sub-discipline shared sciences concerned with effects distribution, structure, function ecosystems, biotic elements cycle (Nuttle, 2002). This combines RodriguezIturbe’s view “the which seeks describe mechanisms underlie ecologic pattern processes” his subsequent observation connection plants balance central ecohydrology” (Rodriguez-Iturbe et al., 2001). focuses consistent Rodriguez-Iturbe’s reference “ecologic processes.” As observes, etymology links relatively broad field ecology. makes little no contribution some areas ecology, e.g. population
