The dynamic system of city is changing constantly. With passing time, some problems such as poverty, disorganized, environmental pollutions, etc., will change the image of some parts of the city and give them a different image which has signs of deterioration. The issue which we face today is recognizing such these urban fabrics which is going out of city cycle and converted to blighted areas Considering that there is no comprehensive description of blighted fabrics, there is neither some indexes for recognizing such these areas, nor research or project in this field. The main purpose of this study is to draw up some indicators for recognizing blighted areas in Iran with social, economical and physical dimensions. For resulting this purpose, 20 indicators with different contexts such as roads network, land use, the percent of arid lands, the existence of deteriorated fabric, the probability of natural disaster occurrence, public facilities and utilities, land value, size of lots, taxpaying, decreasing population, the percent of abandoned buildings, unsuitable urban industrial units and environmental pollutions have been drawn up. At the end, these indicators are studied in the fifth area of region 8 of Isfahan. The results show that this area with including 13 of 20 indicators is blighted.
