Abstract

The global warming period, which continues all over the world, has also taken all climates under its influence. In order to be a solution to this problem, every country around the world produces solutions both within itself and with international unions. Plants are among the most important sources of these solutions. The relationship between air quality and plants is quite different. While polluted air quality affects all living things, even plants, plants help to reduce and improve this damage. In order to minimise and improve harmful emissions in the air, plants are the most important design tool of many professional disciplines, especially landscape architects. This study was carried out in Dubai, the most popular and developing city of the United Arab Emirates. Dubai is a model for the world with its environmental policies and a different herd approach. The main purpose of this study is to reveal the effect of highway planting on air quality. For this purpose, road routes with different characteristics on an important road route of Dubai were selected and analysed for air quality. Four road routes were selected based on the presence or absence of vegetation. In line with these choices, PM10, PM2.5, TVOC, HVOC, CO and CO2 measurements were made, which are among the harmful emissions affecting air quality. As a result of the study, these measurement results obtained from road routes of different character were compared and evaluated according to "air quality indices" and suggestions were made for future studies.

Sıcak Çöl iklimi Koşullarında Yol Ağaçlarının Hava Kalitesine Etkisi: Dubai Örneği

Abstract

Tüm dünyada süren küresel ısınma süresi aynı şekilde tüm iklimleri de etkisi altında almıştır. Bu soruna çözüm olabilmek için dünya çapında her ülke gerek kendi içerisinde gerekse milletlerarası birleşimler ile çözümler üretmektedir. Bu çözümlerin en önemli kaynakları arasında bitkiler bulunmaktadır. Hava kalitesi ve bitkiler arasındaki ilişki oldukça farklıdır. Kirlenen hava kalitesi tüm canlıları hatta bitkileri bile etkilerken, bitkiler bu zararı indirgemek ve iyileştirmek için yardımcı olmaktadır. Havadaki zararlı emisyonları en aza indirgemek ve iyileştirmek için bitkiler başta peyzaj mimarları olmak üzere birçok meslek disiplinin en önemli tasarım aracıdır. Yapılan bu çalışma kapsamında Birleşik Arap Emirliklerinin gelişen ve gelişmekte olan en popüler ili olan Dubai’de gerçekleştirilmiştir. Dubai çevresel politikaları ve farklı bir sürü yaklaşımı ile dünyaya örnek çalışmalar yapmaktadır. Yapılan bu çalışmanın temel amacı karayolu bitkilendirmelerinin hava kaltesi üzerindeki etkisini ortaya koymaktır. Bu amaç doğrultusunda Dubai’nin önemli bir yol güzergâhı üzerinde farklı karakterlerde yol güzergahları seçilip hava kalitesi analizi yapılmıştır. Yol güzergâhları dört adet olmak üzere bitkisel dokunun var olması ya da bitkisel dokunun var olmaması üzerinden yapılmıştır. Bu seçimler doğrultusunda hava kalitesini etkileyen zararlı emisyonlar arasında olan PM10, PM2.5,TVOC, HVOC, CO ve CO2 ölçümleri yapılmıştır. bitkilerin kara yolu hava kalitesindeki etkisi incelenmiştir. Çalışmanın sonucunda farklı karakterdeki yol güzergâhlarından elde edilen bu ölçüm sonuçları “hava kalitesi indekslerine” göre karşılaştırılmıştır, değerlendirilmiş ve gelecekte yapılacak çalışmalar için önerilerde bulunulmuştur.
