Abstract
The concept of diversity has a lot of meanings and there are different menthods to estimate the diversity. One of these methods combines the species richness and the abundance of species (Shannon-Wiener index) providing a good evaluation of the diversity (MAGURAN, 1983). The present work describes the general model of the variation of the diatoms diversity index in the lakes of the Danube Delta.
