Abstract
Urban heat island is one of the most important consequences of climate change in cities. Various factors accelerate tempera-
ture increase in urban surfaces. Widespread use of impermeable materials with high heat capacity; albedo and trapping of
incoming solar radiation in urban structure which prevents reflection; reduction in cooling at night due to increased building
heights; and changes in the complex urban geometry are among these factors. The aim of this study is to investigate the sur-
face temperature of Tehran in a 30-year period (1984–2014). The required images and land surface temperature maps were
prepared using a split-window algorithm on thermal bands of landsat images for four periods. All images had been taken at
11:00–14:00 in summer. Temperature factors were calculated for different neighborhoods, and two patterns were obtained.
One pattern showed the formation of urban heat island in barren lands, large workshop areas, and areas with military land
use, and the other one showed the formation of urban heat island in dense building population areas with limited green
space. The results indicate an increase in the area of the regions with a higher temperature in the city. In 1984, the smallest
area belonged to the above 48 °C temperature category (1.8 ha), while in 2014 the below 25 °C category had the smallest
area (0 ha). It was observed that the area of the former category reached over 1740 ha in 2014. Neighborhood temperature
factors show that 17 Shahrivar and Khajeh Nasir–Hoghoughi neighborhoods are the hottest neighborhoods in Tehran. The
findings in this study may persuade urban managers scientifically to make preparations for changing the life style focusing
on urban macro-scale planning which is a widely emerging issue resulted from recent effects on Tehran’s climate resilience.
Considering the importance of urban planning priorities in urban ecosystem services, it is essential to make use of all urban
elements and fill the empty gap between urban ecosystem services production and their consumption in the city by wise and
smart urban management.

Introduction
As one of the main human habitats, cities have had a sig-
nificant effect on biosphere. Such vast human changes have
introduced undesirable consequences, such as compromising
the quality of environment and its erosion ultimately lead-
ing to a decline in quality of life and violation of the right to
healthy environment. Due to these destructive effects, our
modern cities are becoming more and more vulnerable and
the ability and quality of life are threatened. In other words,
the increase in both rapid and gradual climate changes
causes disasters and their complex social–economic results
in cities make city structures fragile and reduce their resil-
ience to environmental development challenges and level
of technology standards. In the past eras, society by itself
