Abstract

[fre] La recherche d'indicateurs d'environnement correspond à une approche certes descriptive, mais qui a le mérite de déboucher assez rapidement sur le plan pratique. Nous présentons les résultats d'une application au cas de deux lacs alpins : Annecy et le Bourget. Elle repose sur une mise en relation de paramètres de nature hydrobiologique et de données socio-économiques. . L'étude comparée des deux lacs aboutit à dégager une vision globale dans laquelle la pureté de l'eau a une valeur primordiale. Nous montrons qu'il est possible de l'appréhender par deux variables hydrobiologiques : couleur et turbidité de l'eau. Dès que l'on veut aller plus avant, on doit distinguer les diverses fonctions de l'eau. Entre celles-ci, il peut exister des incompatibilités, ce qui pose des problèmes de répartition spatiale donc d'aménagement. Pratiquement, nous avons construit quatre fonctions particulières (fonctions sportive, écologique, ludico-sociale et eau à regarder). Pour chacune, sont proposés des indicateurs particuliers. [eng] Indicators linked to the quality of water and behaviour, applied to the lakes of Annecy and Le Bourget - The search for environmental indicators is a descriptive approach but one which shows practical results fairly quickly. Its application to two Alpine lakes (Annecy and Le Bourget) is based on relating hydrobiological paramètres and socio-economic data. . The comparative study of the two lakes leads to a global impression in which the purity of the water is of prime importance. It is possible to approach this through two hydro-biological variables : the colour and turbidness of the water. As for the various functions of water, there may be certain incompatibilities, which poses problems of spatial distribution and hence of planning. Four main functions (sport, ecology, social, and water to look at) have been set up and for each particular indicators are proposed.
