[Departement_IRSTEA]GMA [TR1_IRSTEA]12 - MILEAU / HYDRECOTheories on the organization of systems (Allen and Star, 1982) learn us that generally structures to large scale govern those to thinner grain and most procedures of classification of the aquatic systems take as a basis on the strong associations and interactions between ecosystems terrestrial and aquatic (Hynes, 1975). The method of ecoregion (Omernik, 1980, Wasson and al., 1993) leans on these properties. It identifies limits through the analysis of homogeneous ecological regions based on the spatial distribution of control factors of the aquatic ecosystem : geology, relief, climate. On the Loire basin, a first survey (Wasson and al., 1993) permitted to identify 6 regions of first l...
