Rapid land use change has taken place in many mid-sized cities of Iran such as Zanjan over the past three decades. This research analyzed the land use/cover change Zanjan from 1965 to 2005; identified the patterns of urban growth and the fragmentation of the urban space by applying GIS and remote sensing tools. The main driving forces of the urban changes were analyzed and the model to predict the land use/cover changes was applied. Our results show the importance of monitoring and modeling of rapid urban growth for attaining sustainable mid-sized cities in developing countries that are strongly dependent on export of natural resources. The results indicated that there had been a notable and uneven urban growth and a major loss of cropland loss between 1965 and 2005. Most of the urban growth and loss of agriculture land occurred in inner and outer suburbs. This research analyzed the land use/cover change Zanjan from 1965 to 2005, identified the patterns of urban growth and the fragmentation of the urban space, applying GIS and remote sensing tools. We believe that in urban growth modeling process there has been multi socialeconomical and physical elements in which have key rules in it, and we attempted to use some of them.Keywords

In the past few decades urban areas of Iran have grown very rapidly. According to statistics bureau of Iran, in 1996, 61.31% of the population lived in 614 urban centers-some 36 million. By 2020, this figure is estimated to rise to 80 %. This rise in urban population has resulted in continuous creation and growth of squatter settlements and in spreading of civil services until the breaking point. Serious shelter shortages, overcrowding, decreasing of the standards of public health and sanitary services, deterioration in the quality of living are the bitter fruits of the urban expansion in Iran. In this article based on a broad field study, we try to show some of physical environmental bitters which informal settlements in Iranian cities are faced with, especially in Tabriz city as a fourth biggest metropolitan area based on GIS analysis. This research is prepared in 3 parts: Part 1 the case of Tabriz city, Part 2: physical and man-made hazards, Part3: Evaluation of land tenures and dwellings.Keywords
