Abstract

Field measurement and satellite images show that centers of major cities such as Tehran are hotter than marginal points, so that after drawing an isothermal map or interpreting aerial photos, heat focuses are seen throughout the city especially in central and accumulated parts known as "Heat Islands" effect. Exactly the opposite is also true. As, there are some parts, throughout the city which are cooler than other adjacent ones. These areas often contain large GREEN FIELDs. Using anti-thermal focuses or GREEN FIELDs is an efficient solution, compensating adverse impacts of heat islands by decreasing relative temperature. In the present study to demonstrate adjusting effect of GREEN FIELDs, Taleghani Park was selected as a vast city based park and 30 various temperature measurement stations were planned within the margin and deep inside the Park. Temperature measuring was carried out 6 times by 2 persons. To make a comparison between depth and margin temperatures, measurements were done at the same time in a number of stations in order to ensure equality of all environmental conditions (excepting vegetation density) for all stations.As measurement finished, a temperature table was made really for each time, the column of which showed particular conditions of each station that were thought to be effective, including existence or mm-existence of VEGETATION COVER and vegetation density. Afte preparing temperature tables, heat maps consisted of a mean temperature map for each station and a map to subtract station mean temperature from the city's temperature were provided, in which average temperature of each station was compared with the city's. Then a diagram was prepared for each map. Results obtained revealed that adjusting effect of green are on the temperature decrease reached causes a fall to 3.07oc within the coolest station (Station no.16). They also show that as you get distant from park margin and closer centre of the green, mean temperature of stations becomes more difference than from the city's temperature area.For solving problems such as heat island effect and global warming it is to establish vast parks. Other proposed solutions include review of tree types (from the view point of their adaptability to urban environments), appropriate pruning to achieve maximum and further use of deciduous plants instead of conifers and of green roofs.
