摘要

The inventory of 32 aquatic invertebrates' taxa sign of a relatively good water quality. The settlement of these macroinvertebrates of running water presents a balance of distribution at the study site that is characterized by an average altitude andrelatively low water flow to disturb. This stand is marked by the absence of Plecoptera. These results were well check by calculating diversity and fairness. Pollutant species located further downstream are negative indicators because they are inferred from pure water. Among the indicators of clean water we will cite as benthic invertebrates: Ephemeroptera Heptageniidae, some families of coleoptera such as Elmidae and to a lesser extent trichoptera. The diagnoses using the presence of biological indicators species are based on two phenomena which appear jointly downstream from an allogeneic supply of substances liable to assimilation according to the classic schemes of self-purification processes. The organization of the stationary communities is closerelated to environmental conditions (current velocity, water temperature, substrate riparian vegetation and chemical characteristics impacts). The floods depend directly on the rainfall regime and appear as one of the conditions unfavorable to the lifeof the aquatic fauna by the sudden modifications of the environment and the disappearance of certain species. After the flood recolonization takes place according to species and habitats.
