WETLAND VEGETATION AND ALGOFLORA OF THE LAKES OF KUR-ARAZ LOWLAND

Summary

The article provides the results of the researches at wetland vegetation of Mil plain and its geobotanical classification. Distribution, contemporary situation, species biodiversity, morphobiological, bioecological and phytocenological features of this vegetation was analyzed. Plant formations and associations were given together with edificators classification scheme were elaborated. It was determined that wetland vegetation type of researched area contains three formation classes, eight formations and 16 associations. Reed marshes formation class is represented with two formations: Phragmitetum and Carexeto-Phragmitesetum. Phragmiteta australis assosiation of Phragmitetum formation is one of the most distribited assosiations of the fresh water basins of Kur-Araz lowland. Grassy marshes formation class is represented with three formations: Cynodoneto-Phragmitesetum, Alhagieto-Phragmitesetum, Cynodoneto-Alhagietum. Shrabby-perennials marshes formation class includes three formations: Tamarixeto-Phragmitesetum, Typhaeto-Phragmitesetum and Tamarixeto-Carexetum. As well as the species content of plankton and bentos of Aggol and Sarisu lakes was also defined and results of ecological analysis of these lakes were given. During researches of algoflora of the lakes of researched area 50 algae species were found which belong to three divisions. Species of Pennatophyceae class of Bacillariophyta division have been dominated with 30 species. It was also determined that at the researched lakes the characteristic feature of phytoplankton is abundance of bentos species and scarcity of plankton ones.
