Kentsel Alan Kullanımlarının Zamansal Değişimlerinin Hava Kirliliği Üzerindeki Etkisi

Dünya nüfusunun hızlı bir şekilde artması ve buna bağlı olarak kırsal alanlardan kentsel alanlara sürekli göç olmasından dolayı kent nüfusları sürekli artmaktadır. Artan kent nüfuslarında insan etkilerinden dolayı sağlık yönünden zararlı kirletici etmenler oluşmaktadır. Bu çalışmada 10 yıllık Landsat TM uydu görüntülerinin kontrollü sınıflanması sonucunda Iğdır Kent Merkezi’nin büyümesi ve buna bağlı olarak hava kirletici etmenlerinin değerlendirilmesi yapılmıştır. Çalışma sonucuna göre Iğdır Kent Merkezi’nin 10 yıllık zaman dilimi içerisinde yapısal kısmının % 19,9 oranında büyüdüğü ve buna karşın aynı oranda açık yeşil alanların küçüldüğü belirlenmiştir. Sonuç olarak kent merkezinin büyümesine karşın hava kirletici etmenlerinde azalma belirlenmiş ve bu azalmaların kullanılan yakıt cinsi değişikliği ve meteorolojik etmenlerden kaynaklandığı gözlemlenmiştir.

The Effect of Time-Changing of Urban Areas on Air Pollution

Due to the rapid increase in the world population and consequently the continuous migration from rural areas to urban areas, urban populations are constantly increasing. In the increasing urban populations, harmful pollutant factors are formed due to human effects. In this study, as a result of the controlled classification of 10 years' Landsat TM satellite images, the growth of Iğdır City Center and the related air pollutant factors were evaluated. According to the results of the study, it has been determined that the structural part of Iğdır City Center has grown by 19.9% in the 10-year period and the light green areas have decreased in the same ratio. As a result, despite the growth of the city center, a decrease in air pollutant factors has been determined and it has been observed that these decreases are caused by the fuel type change and meteorological factors.
