Annually, earthquake damnify many countries dramatically and damages human communities physically and psychologically. Regarding absolute annual average of people facing earthquake threat, Iran ranks 7th in Asia and 13th in the world. Throughout history, Qiru Karzin city has always faced devastating earthquakes which have resulted in many losses and damages in rural and urban areas. In this regard, spatial information system can play an influential role in identifying areas facing earthquake hazard, their dispersion, the quality of physical structure in danger and analyzing economic, social and demographic features of the area in danger. The present study seeks to identify secure and unsecure zones and find appropriate locations for crisis management bases in Qiru Karzin. To reach this goal, information received from different criteria is studied and classified into three classes of natural variables, physical variables and institutional-management variables. Then, information layers of different criteria are entered into GIS environment and standardized using Fuzzy linear functions. Later, maps are integrated using Fuzzy Plus. Finally, appropriate and inappropriate zones are identified regarding risk taking and construction of crisis management bases. According to the research results, three villages were selected based on their capability for creating crisis management bases in three levels. These villages will aid rural municipalities (Dehyaris) in the process of crisis management in Qiru Karzin and in reaching goals of crisis management bases using geographic information system capabilities .

Factors of the natural-ecologic, social, economic, historical and political environment affects formation, establishment and organization of rural environments. Thus, the present article seeks to clarify the influence of natural elements (natural-ecologic environments) in transformability of spatial organization in 11 rural districts of Lavasan-e Kuchak village. Descriptive-analytic methods and secondary-research methods are used for collecting information. Moreover, models like Gatman institutional measurement, value of centrality, total minimum distance, number of direct links, number of communicative nodes and demographic capacity are also considered. Results indicate that natural elements, especially topography, water resources and slope have influenced the position of rural settlements. This has resulted in the spatial organization of the study area possessing a two-level hierarchical structure. Moreover, based on the results it is suggested to form spatial organization of the area with three rural areas of Afje, Kantiya and Bujan villages and a rural complex of Lavasan city.
