PARKLARIN HAVA KİRLİĞİNİ AZALTICI ETKİSİNİN ÇORUM ÖRNEĞİNDE İNCELENMESİ

Günümüzde hava kirliği, insan sağlığı ve yaşamına olumsuz etkileri ile en önemli çevre sorunlarından biri haline gelmiştir. Özellikle yoğun insan yerleşiminin olduğu kentsel alanlarda hava kirliliğinin azaltılması ile ilgili olarak alınabilecek önlemler büyük önem taşımaktadır. Ağaç ve çalı örtüsünün düzenleyici ekosistem servislerinden biri olarak hava kalitesini arttırdığı bilinmektedir. Bu çalışmada, yoğun hava kirliliğinin görüldüğü bir şehir olan Çorum’da, 1643 ha alana sahip Bahçelievler Mahallesinde, ağaç ve çalıların çeşitli kirleticileri havadan uzaklaştırma miktarları i-Tree Canopy aracı kullanılarak hesaplanmıştır. Sonuçlar, çalışma alanının sadece % 14.8’inin ağaç ve çalı örtüsü ile kaplı olduğunu ve bu alanların yılda yaklaşık 2.6 ton PM10 (10 µ’den küçük, 2.5 µ’den büyük parçacıklar), 379 kg PM2.5 (2.5 µ’den küçük parçacıklar), 7.8 ton O3, 783 kg NO2, 494 kg SO2, 144 kg CO’ i havadan uzaklaştırdığını göstermiştir. Bu çalışma ile yeryüzü şekilleri ile ilişkili olarak havada biriken kirleticilerin dağılmasının güç olduğu Çorum gibi illerde park ve bahçelerin varlığının önemi ve yeni yeşil alanların oluşturulmasının gerekliliği vurgulanmıştır.

INVESTIGATION OF MITIGATING EFFECT OF THE PARKS ON AIR POLLUTION IN THE CASE OF CORUM

Currently, air pollution has been one of the most important environmental problems with its negative impacts on human health and life. The precautions that can be taken against air pollution is very crucial particularly in urban areas with dense human population. It has been known that tree and bush cover as a regulating ecosystem service can increase air quality. In this study, I investigated the amount of air pollutants that are removed from the air by trees and bushes using i-Tree Canopy in Bahcelievler, a 1643 ha district of Corum, a city that is suffering from dense air pollution. The results showed that only % 14.8 of the land is covered by the trees and bushes in the study area. They remove annually 2.6 ton PM10 (particles smaller than 10 µ and bigger than 2.5 µ), 379 kg PM2.5 (particles smaller than 2.5 µ), 7.8 ton O3, 783 kg NO2, 494 kg SO2, 144 kg CO from the air. I underlined the importance of current parks and the necessity of extra green spaces for the cities in which dispersion of the air pollutants is difficult because of the topography such as Corum.
