Küçükçekmece, is one o f the important districts to define the city o f Istanbul at the international level with its historical, cultural, and natural values. In this study, the parks in Küçükçekmece District were examined in terms o f ecological quality, principles, and standards. Ecological quality is a composite o f the structural and functional features determining the habitat values o f a landscape. An objective evaluation on the ecological quality of parks is important from the point of rehabilitation from an existing situation, and providing areas which will have high habitat value in the future. Recovery in the existing park area will generate a livable urban atmosphere. In line with this basic comprehension, the ecological quality of the parks in Istanbul's Küçükçekmece District was examined. There are four principles determining ecological quality of an area: vegetative production, water, permeability (soil), and natural vegetation cover (biological diversity). This research was done in two phases regarding the permeability and natural vegetation cover using ecological quality principles.
In the first phase o f the study, a vegetation list was provided by the Park and Garden Department o f the Küçükçekmece Municipality. The park names and size were acquired from the "Küçükçekmece District green corridor Transformation Project". The space where the soil surface is covered by soil material, or is suppressed because of overuse and can not sustain plant growth is accepted as an impermeable soil surface. Whether there is a relation between park areas and permeable surface areas was examined using the Spearman correlation test. Whether permeability ratio o f parks changes according to their location was analyzed using the Chi-Square test.
In the second stage o f the study, the existing vegetation cover was analyzed on-site. Existing vegetation cover analysis is made according to trees, shrubs, bushes, flowers, and trailings. Findings of, this study show that the average permeability ratio is 35.19% and the naturality ratio is 52% in the 63 parks under examination. This study shows that the permeable land surfaces o f the parks remain incapable o f sustaining vegetative growth and therefore the habitat values o f the park areas, which can have an economic, social and ecologic contribution to the urban environment, will reduce.
Result o f this study will contribute to the sampling used for the ecological quality principles in other parks in other districts. The study reveals the importance of the ecological quality factors that need to be taken into consideration in the design and planning of parks.
