Urban population growth and increasing demand for housing and services in the cities of the country has forced the need for physical development of cities this development in recent decades has been more of external development, and the provision of services and housing has been following by adding to the city's area, that has caused to urban sprawl and deterioration of surroundings and neighboring gardens and agricultures. While that infill development and particularly redevelopment and utilization of land as effective approaches can be considered in reducing damage to the environment and realization of sustainable development of cities. In this regard the aim of this research is to develop a model to identify lands with redevelopment capability and use it to the city of Arak as an example. Therefore, this research tries to answer these questions that how to identify the lands with redevelopment capability? And what are these areas in Arak? For this purpose, an innovative algorithm to identify lands with destruction and redevelopment capability is designed, that urban parts are evaluated on the basis of 8 criteria, construction quality, age of Construction, small lot, permeability, land's price, sponsorship rate, ratio of migration and access to green space. This innovative algorithm has been implemented for example in the city of Arak. The results show that innovative algorithm has nice capability in combination with GIS software and can be used to identify the lands with destruction and redevelopment capability. Also using this algorithm in Arak city lead to identify 4187 pieces with redevelopment capability which has an area of 85.8 hectares and can be used to realization of infill development in Arak city.

One of the subjects that most cities of the world are faced to it is the subject of natural occurance the crisis management is necessary. for the quick and correct performance of decisions to reduce the hurt and their effects before, during and after the natural occurrences.This management is related to planning, urban management and also geography.Using the urbanism principles such us texture, urban structure,and use of urban lands, relation networks and urban substructures and so on,we can reduce the effects of natural occurrences a lot.The goal of this study is the spatial allocation of temporary settlement centers in the district six of Isfahan city in environmental crisis using GIS and the correct management of the past, during and after the crisis. The methodology of the research is descriptive and analytical that using the technique of AHP and using the graphic software ARC/GIS to provide the map and spatial allocation of temporary settlement centers, the problems of the parks and the rescue centers of the district six of Isfahan city with the crisis management have been researched. The kind of research from the point of goal is application.The results show that 1) The parks don’t have suitable numbers and distribution. 2) The rescue centers don’t have suitable numbers and distribution. 3) Also they face to lack of the equipments and installations For this reason, some programs have been offered to Power the district six of Isfahan city against the destructive effects of the occurrences from the point of crisis management. Based on the results of this research using the upper technique and regarding the various standards such as the distribution of electricity centers, fire station cure centers, fuel centers and so on in district six of Isfahan city, the suitable regions of temporary settlement have been recognized and preferred.
