Abstract:
The main objectives of this study were to compare soil properties and plants of both sides of the Acıçay River and
evaluate relationships between salinity and landscape positions under the condition of semi-arid climate. Right side
of the Acıçay River lands has been generally used for agriculture crops, while left side lands used for grassland. Soil
properties and plant composition differentiate in the right and left sides of Acıçay River in Çankırı city which is
chosen for a research area. The change on salinity and topography affect directly vegetation and variety of land use.
With the aim of determining soil-plant interaction ,salinity has been determined in the plant-root area from two
different depths (0-20cm-20-40cm) in the right and and left sides of Acıçay River and floristic composition is
introduced in this region. Salt ratio in upper soil increases when you go near to the watershed. Salt and EC values of
soils are measured high in left sides. Besides salt and EC values decline as you come up the slope through the stream.
As a result of assessing plant samples which are collected at the time of land study, belonging 26 family 70 species
and 110 taxon (including species and sub-species ) have been ascertained.The richest families in the research area are
Asteraceae, Fabaceae, Lamiaceae, Poaceae ve Chenopodiaceae. The ratio of the five of the richest family to the
total species is 56.37. The ratio of the species dispersed in the rest 21 family is 43.63%.
