Site Selection and spatial distribution of urban planning has an important role in the city's economy and its economic stability. Today, inharmonious distribution in some areas and the urban districts has led to conflict, increasing transport costs and environmental pollution. Compatibility index of land uses affect directly and indirectly on the stability of the city's economy. The aim of this study is to analyze the condition of urban land use based on compatibility index in order to achieve sustainable economic in Tehran 1st District. In this study compatible creterias of land uses including distance from the fault line, land uses proximity with infected and annoying user, land use site selection based on slope is used. The research is practical research and its method is descriptive-analytical method, using Geographic Information System (GIS) and (excel) software. The data and informationwas collected from library documents, Digital Maps of the study area were analyzed using GIS. Findings and results showedthat about 40% of locating is located within 700 meters from the fault line and there is a hazardous district. More than 20 % of land uses have located in inappropriate slope and about 0.3 % of land uses in terms of environmental pollution and nuisance are unfavorable land uses as well. Overall, various financial, casualties and irreparable losses to follow in present and future that finally will follow Urban Economic volatility.

Iran is one of the earthquake-prone countries in the world. Almost 90% of Iran is located in an earthquake belt. Based on seismic zoning maps, Tehran metropolitan area is highly dangerous and unsafe. Tehran’s district 1 is situated in one of the main Tehran's faults called North Tehran fault. Since recognizing the deleterious factors plays an important role in reducing earthquake dangers, so analysis of these factors can have a significant role in controlling the harmful factors and reducing death toll and financial losses.
The main goal of this study is to identify the most important predisposing factors which result from earthquakes in Tehran's district 1, also to distinguish target areas according to their level of vulnerability as high, moderate and low is another aim of this paper. Data and information collected in this study are spatial, statistical and descriptive. The method of research is descriptive-analytic. In this paper, also the geographical information systems (GIS) have been used. The results indicate that the most important predisposing factors in the region are by an order of preference: the distance from the fault, the slope of the land, proximity of incompatibilities with applications, the building's life, population density, lack of access to open spaces and urban areas are parts. The most vulnerable regions of this area are 8-6-10-4 respectively.
