Numeric Methods and Some Computer Programs Used in Phytosociological Works

As the phytosociological works in Turkey are examined, it can be seen that they were mainly focused on the classification of plant communities, but the number of the studies on ecologic, biologic and structural properties of the plant communities are not many. In this sense, numeric techniques (ordination and classification) and computer programs including these techniques are important assistant tools. The classification of plant communities and determination of their ecologic, biologic and structural properties is much easier today thanks to these techniques and computer programs. In this work, some knowledge were presented about ordination and classification techniques, which are widely used in vegetation science in the world and especially in Europe. TURBOVEG data base management program and JUICE program, which is used to classify and arrange the vegetation data were also presented. Keywords: Phytosociology, Juice, Ordination, Classification, Turboveg.
