Abstract Inclination towards urbanization and population increases have acceleratedthe growth of cities and city life This trend has had harmful effects on theconservation of natural environment the growth of cities has caused the farms andsuburbs to be changed to houses and industrial centers this has diminished thegreen areas The maintenance of a proper balance in cities needs convenient managementof the resources and city planning To achieve this end one needs to take a look atthe conditions of the past to have a sound judgement and proper decisions forboth the present and the feature The development of cities has increased theleisure time of the people and has made them dependent on the urban green space Therefore the urban green space needs to be reconsidered for ecological reasons Evaluation and revelation of variations is a process which in its course thevariations of a phenomenon are determined by observing it in various periods Inother words it is a method for determination and manifestation of differences in atleast two images in different periods of time Revelation of variations helps theplanners and managers both in monitoring the growth and development of city aswell as monitoring plants during growth period and etc Isfahan City Garden is one the cities that has changed in visage due todevelopment of a majority of industries excessive immigration of villagers foundation of satellite towns in suburbs and the existence of impeding usages thus the excessive growth of the city has destroyed a vast area of fertile lands andhas reduced the green spaces In this study the aerial photographs of 1334 have been compared with thesatellite images IRS P6 of 1386 to display the changes in the green areas Tothis end overlaying and post classification methods has been used Therefore theland use map was developed for two mentioned dates and then they werecompared with each other Investigation results shows that in a 52 years timeperiod the green spaces area has decreased over 30 percent in which the highestvariation in usages is related to transformation of agricultural lands to humanmade relieves and in the second instance it is caused by transformation ofuncultivated lands and pastures to human made relives in such a manner thatagricultural lands area has decreased from 21529 7 ha in 1955 to 11193 1 in 2007 30 percent of decrease and the uncultivated area and pastures from 6811 7 in1955 to 3403 8 in 2007 9 08 percent of decrease This investigation offers a more accurate estimation of green spacescomparing to the similar investigations through segregation of fallow areas inaddition to green areas available in the time of photography This study shows theimportant of remote sensing data in exact investigation of land and changedetection for outmost time efficiency
