In urban areas, harmful influences of natural disasters include a combination of physical destructions and disruption in functions of urban elements. Destruction of structures and residential buildings, route networks and access points like bridges and communication roads and basic installations like water reservoirs, power plants, telephone lines, electricity, water pumps, gas, etc. are among these physical destructions and disruptions. Transportation network is the most important element in helping people and saving their lives after earthquakes. Optimal functioning of transportation network can decrease direct and indirect influences of crisis. This shows the importance of time and decreasing delay time in helping victims. Optimizing traffic allocation and finding the best place for fire stations in Dehdasht city are among goals and objectives of this study. It analyzes urban transportation network using GIS. A map is produced to show optimal places for building fire stations in Dehdasht city in regard to the situation of the present stations and also considering limitations and problems, weak and strong points.

Recently, the necessity of considering natural resources as the basis and foundation for the development of economic infrastructure in developing countries (like ours) has become quite clear. The necessity of decent development and management, allocating facilities, using domestic potentials and knowledge of natural geographical spaces are among the priorities of the country management. Nowadays, planning has been accepted as the most influential tool in facing complex problems and providing key solutions for managing crisis and allocating facilities. This requires a holistic and complete knowledge of the geographic area on one hand, and integrated, synchronic analysis of all influential elements in that area. This knowledge and analysis needs a system which can store all spatial features in an information bank and represent them according to the needs of the planner in the form of map and information tables. Geographic Information System (GIS) has been introduced in the last decades as one the most influential planning tools in collecting, analyzing and representing information visualy. The present article seeks to investigate the status and role of information system in different studies on natural resources and its influences.

Tourism development in deprived regions with necessary tourism potentials is a strategy which has recently attracted the attention of different countries of the world. In different parts of the world, preserving the environment, ecosystem and the wildlife are considered important. The present article investigates geomorphology of Ilam Province in Western parts of the country emphasizing on geotourism resources. Geomorphologic diversity of the province have created unmatched resources in geotourism which are able to turn the Province into a tourist attraction. The present study identifies geologic and geomorphologic characteristics of straits in this Province and provides necessary solutions for using this valuable resource. Moreover, it identifies unique features of this landforms emphasizing on their attraction.

Today, we are facing with the ever-increasing advances in remote sensing and aerial photography and satellite imagery, with the increasing use of remote sensing and GIS in environmental planning, especially in various branches of natural sciences and earth sciences. In this paper, we have tried to examine the role and application of satellite imagery in environmental studies. GIS can be considered a high-level mapping product. The term "GIS" has been used in recent years as synonymous with the rapidly emerging technology for the processing of spatial data. GIS can be defined as a powerful set of computer tools for collecting, storing, restoring, transmitting and displaying spatial data from the real world for specific purposes.

Today, the increasing trend of urbanization and concentration of population in cities in all countries of the world is indisputable. But this phenomenon has not have the same results everywhere. In industrial societies, due to balanced economic, political and social growth, the mobilization of human forces in cities has been utilized in the best way and toward a comprehensive development, while in the third world countries, due to lack of appropriate infrastructure, heterogeneous growth and the invasion of population to the cities has caused many social problems and has involved governments with a serious and deep challenge. The creation of irregular homes and Ghettos in large cities and metropolitan areas in backward communities, which have been formed due to lack of proper absorption of work-seeking and mostly rural migrant population to these areas, are among the biggest and most important issues that have occupied the planners and decision-makers minds in such communities. It has been proved through experience that this phenomenon, if dealt with improperly and without careful and in-depth study, will be the source of many other social irregularities. This article is an attempt to understand the spatial-social separation phenomenon in urban neighborhoods (Ghettos) and its effect on the fabric and structure of cities and finally, the study of this problem in Tehran as the capital of Iran - a city that any intervention and planning in it directly and indirectly affects other cities of the country - and to propose appropriate solutions in relation to native and national culture to deal with this issue. The results of this study show that the policies of neglect and elimination of Ghetto neighborhoods have been not only ineffective, but, on the contrary, have resulted in many negative outcomes such as an increase in abnormalities and social problems. The provision of facilities and the establishment of laws and encouraging policies by the government and, in other words, changing the attitude of looking down on these neighborhoods and paying them and their inhabitants respect and attention will make the Ghetto-residents themselves to provide conditions for improvement of their homes and their residential textures, and will help improve their economic and livelihood so that they leave their self-made houses and be absorbed into other urban neighborhoods and developed urban areas.
