Özet

Linear plant compositions establish a connection between rural and urban landscapes. The green fields, which are abundant in rural areas, are diminished in urban spaces due to rapid urbanization. This problem can be solved by using linear planting techniques in urbanized places. Nearby establishing green corridors in cities, linear planting serve as very nice visual compositions and provide functionalities. Linear plant compositions, which are quite important for the city, were examined owing to 3 different purposes. The first is the identifying of the plants having been used in linear green compositions. The second is the determining of the functional differences while the last one is preference and visual perception differences depending on users. In this study, totally 32 species were identified. Ligustrum japonicum, Biota orientalis and Hydrangea macrophylla were recorded as the most common species. The se linear compositions were used as barrier with the rate of 78% in residential areas and 50% in open green spaces, as border with the rate of 40% in public spaces, as curtain with the rate of 86 in public areas, as separator with the rate of 87% in transportation areas. Visual quality of linear compositions was assessed by using chi(2) analysis. Statistically reliable (%95) P<0.005 results were found between user and visual quality As a result, linear plant compositions in Trabzon possess evergreen plant species by 70%. In addition, the linear plant compositions looking aesthetic were identified to be preferred more according to Semantical Differential Technique.
