Tuz gölü çevresi halofitik vejetasyonda zonlaşmaya etki eden faktörlerin belirlenmesi

Bu calisma Tuz Golu cevresindeki halofitik vejetasyonda zonlasmayi etkileyen temel faktorlerin belirlenmesi amaciyla yapilmistir. Arazi calismalarinin devamliligi ve vejetasyon donemi dikkate alinarak bolgeden 9 aylik toprak verileri toplanmistir. Her bir zona ve aya ait olan toprak orneklerinde pH, EC, katyon ve anyon analizleri yapilmistir. Elde edilen veriler arasinda birbiri ile ayni etkiye sahip olanlarin ayrilmasi icin ANOVA ve TUKEY testleri uygulanmis ve farklilik gosteren degiskenlere CCA (Canonical Correspondence Analysis) uygulanarak her birinin turlerin dagilimi ve zonlasmasi uzerindeki etkilerine bakilmistir. Aylik olarak yapilan analizler degerlendirildikten sonra yillik ortalamalar goz onunde bulundurularak zonlasma uzerinde etkili olan temel degiskenler su sekilde tespit edilmistir; su ile doygunluk, pH camur, EC, Ca+2, K+, HCO3- ve KDK.AbstractIn this study it was aimed to define the major factors effecting the plant zonation athalophytic vegetation around Salt Lake. By considering the contuniuty of the field tripsand the vegetation period, soil data were collected through 9 months. The pH, EC,cation and anion analysis of the soil samples belonging to the each zone and monthwere done. For determination of the factors having the same effect on zonation ANOVAand TUKEY tests were applied and the factors having different effects were defined.CCA (Canonical Correspondence Analysis) were applied to the factors having differenteffects and their influence on species distribution and zonation were examined. Afterthe evaluation of the monthly results, by considering annual mean values it was foundthat pH mud, EC, Ca+2, K+, HCO3- and CEC were the most effective factors for plantdistribution and zonation around Salt Lake.2006, 203 pagesKey Words: Salt Lake, halophytic vegetation, plant zonation, salt marsh
