Abstract

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

Abstract

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.
