Abstract (2. Language): 
In this study, the Physiological Equivalent Temperatures (PET) of different land patterns in the Ankara urban area has been analyzed. The spatial distribution and temporal variation of the thermal perceptions and the grades of thermal stress caused by the thermal conditions have been determined for 00:00, 03:00, 06:00, 09:00, 12:00, 15:00, 18:00 and 21:00 hours during the December and July of 2010. The effects of physiographic features such as elevation, aspect, slope, and especially land use, on the PETs have also been examined. According to the analysis which is carried out by using PET thermal perception index, in the research area the thermal comfort values varies around from -6 to -11°C in winter and from 13°C to 50°C in summer. In both periods the open spaces (grasslands) of the city forests have the maximum PET values during the day. Either in December and in July the urban area (city center) has and cool island during the day and has a heat island during the night.

Abstract (Original Language): 
Bu çalışmada Ankara şehir merkezi ve yakın çevresindeki farklı arazi dokularının Fizyolojik Eşdeğer Sıcaklıkları (FES) analiz edilmiştir. 2010 yılının aralık ve temmuz aylarını kapsayan çalışmada, 00:00, 03:00, 06:00, 09:00, 12:00, 15:00, 18:00 ve 21:00 saatlerinde gerçekleşen termal algılamaların alansal dağılımı, zamansal değişimi ve termal koşulların yol açtığı stres dereceleri ortaya konulmaktadır. Ayrıca FES’ler ve termal algılamalar üzerinde başta arazi kullanım olmak üzere, yükselti, bakı, eğim gibi fizyografik özelliklerin etkileri incelenmektedir. Çalışma alanında FES termal algılama dizini kullanılarak yapılan analizlere göre, kışın -6°C-11°C, yazın ise 13°C-50°C arasında değişen termal konfor değerleri görülmektedir. Her iki dönemde de şehir ormanlarındaki açık alanlar gündüz saatlerinde en yüksek FES değerlerine sahiptir. Gerek aralıkta gerek temmuzda gündüz saatleri boyunca şehir merkezinde soğuk, gece saatlerinde ise sıcak ada oluşmaktadır.
