Analyzing City Structure with Defense Perspective During Wartime with Emphasis on Distance as a Factor (Case Study: Turkmen Port City)

Humans have continuously experienced war scenes and military confrontations during the history and very few regions have been immune to this pestilence. Reinforcing the urban defensive facilities, embedding escape routes from danger and improving the service state is necessary in times of defense and an inevitable matter. From this manner, the effort of humans for survival has made them desperate to be equipped before the threats. Nowadays, city as the most important inhabitance of humans must provide different human requirements. Based on the importance of    the subject, the present study is evaluating the subject in the Turkmen port city with an     applicable- developmental approach and a combination of descriptive- analytical methods. In our proposed method, the city and its urban elements which are effective in passive defense are analyzed regarding their distance from the city center by which we have sought decreasing the probable damages caused by human and natural disasters. Occurrence of natural and human disasters creates heavy damages. This matter makes consideration of aspects of vulnerability and reaching urban welfare standards from the passive defense perspective inevitable. In order to recognize the vulnerability elements with the passive defense approach in the city of Turkmen port considering the previous studies in this subject, the AHP method was used. In this manner, after identifying the criteria, the effort was made to conduct the location database in the geographical information system (Arc GIS). After standardizing these criteria with the AHP method, in the software atmosphere each criterion was given a certain weight using the identification tools. Then with combination and collaboration of these criteria, based on the AHP model, the final map which defines vulnerable areas in three categories (low, medium and high) was drawn. The effective urban criteria such as distance from medical centers and public transportation centers, etc. were also evaluated and based on them the urban zoning and vulnerability were presented.
