Contribution a l’étude des mécanismes d’eutrophisation dans le lac de Tunis : évolution des paramètres physico-chimiques et biologiques

Abstract

Physical, Chemical and biological parameters cited here as monthly and annual overages are measured over 28 stations and from october 1975 to january 1977, within the north part of the lake of '!'unis.
The time and space variations are imftortant, irregular and seem to be de^ndent upon climatical and biological factors.
These fluctuations are related to an advanced State of euuophication which makes the lagotjn ecosystem very complexe.
l^e calctdation ofcortelation fortors between some most imftortant ecological parameters h as been done in the aim to understand some mecanisms of the eutrophication within that lagtton.
