【 摘 要 】

The role of aquatic vegetation in wetland ecosystems is closely related withtheir abundance, diversity and distribution, which in turn represents synergyof various environmental factors. The floristic composition of the aquaticvegetation in two neighboring lakes (Vegoritida and Petron) in north-centralGreece was investigated by means of 160 relevés, which were recorded usingthe Braun-Blanquet method. The analysis of relevés based on TWINSPANclustering showed the existence of 10 plant communities from the Lemnetea,Potametea, Phragmito-Magnocaricetea and Juncetea maritimi classes. The mostimportant environmental factors for the vegetation differentiation in thestudy area, according to the ordination diagram, are light intensity andwater depth of the habitats. The plant species diversity was quantified withspecies richness, Shannon Diversity and evenness indices at a scale of eachrelevé, with a sampling size of 20 m2. There was a clear differentiationbetween the relevés at the more eutrophic Petron Lake and those at VegoritidaLake. The mean plot diversity was also calculated for each plant community,to enable comparison of the diversity indices among the communities at theplot level.
