Introduction: Environmental change issue, as one of the environmental problems, has attracted scientist’ attention. Geomorphology is one of the sciences that trace the environmental changes based on geomorphological evidences. Evidences represent that, in earth history, climatic setting of every region has often changed and therefore geographical and geomorphological conditions have altered. Since the formation of civilization focuses especially cities depend on morphologic setting of regions, great flat plains with low and smooth surfaces are favorable places for habitation but plains in mountainous regions, as Aspas plain, don’t provide appropriate situation because of the lack of favorable geographical parameters.

Introduction: In recent decades, one of the most important outputs of rapid urbanization and physical development of cities has been the disintegration in distribution system of urban services centers and the basis for inequality of citizens for achieving to city service system.  Unfortunately, majority of these studies have been done regarding land use and per capita of land plans and accessibility of residents to site services, efficiency of city services, kind of city services, and the relationship of city service distribution with social and economic characteristics of city neighborhoods has been ignored.

Introduction: The hierarchical tourism areas, in fact, are criteria for determining the centralization and adjusting the in equality between different regions. Little has been published, up to 1990s, in terms of doing hierarchy of tourism areas. But during last decades, investigators have paid more attention to make areal, national, ultra national hierarchy of tourism industry.Today, with advances in statistical and digital systems and by using different indices in various fields, geographical studies have facilitated the process of tourism areal hierarchy.

Introduction: Nowhere in the world is free from the risk. However, with increasing population and their relevant needs, the destruction and damaging power and magnitude of both natural disasters have been intensified. In other words, the Earth is more vulnerable than it used to be.In this context, disaster management headquarters in Tehran raised and adopted the original plan for disaster management in Tehran. The main goals of Construction of this site is to provide tactical and operational platform for achieving the appropriate preventive measures, preparedness and coping with various crises, particularly the great natural crises such as earthquakes, accelerate network development and system evaluation reticulum incident, and conduct operations control center of city of Tehran.

Introduction: Provides airport, were. Because of the nature and frequency of flights of aircraft at the time and lack of continuity, noise pollution will not cause problems for society. In addition, low population density in the vicinity of airports and air traffic light, the occurrence of an accident would prevent dangerous for urban communities. The extraordinary growth of air traffic has increased the likelihood of negative reactions. But the spread and evolution of the aircraft, the most profound effect on the relationship between urban communities and the airport is laid. Increasing the size and speed of the aircraft equipment required to increase their landings and changes in construction and combination bands in the airport is functional. It also increases the power output of aircraft engines cause noise pollution is inevitably the case (Safarzadeh and Mahmoud, 1383: 84-82).

Introduction: Every city use includes traffic specification the changes by transportation planning cause objective manifestation in general texture of the city. This manifestation involves promotion and demotion of spatial texture of city that is through optimization, reconstruction, expansion and creating new obstacles. Transportation planning is a new subject in geographic science and its use in city planning in general and regional planning in particular has strated recently. The transportation system and traffic are parts of city's activities and they indicate the dynamism and vitality of a whole city. There is no doubt that without transportation, one can not imagine a vital and dynamic city.

Today the protected areas including national parks are recognized as among the most beneficial forms of multi-aspect and stable productivity. Green spaces are appropriate places for the citizens to spend their leisure time. The main objective in designing of green space is to attain its social and mental effects in making human closer to the nature as far as possible. Nowadays, sociologists, psychologists and physicians believe that in addition to important implications for public and environmental health, green space plays positive role in the health and well-being of community as well. The fundamental objective of the present research is to developed an experimental model which can determine the parks function and provide a scientific base to identify the factors that affect the urban parks function.
