The Design and Location Assignment of Multi-Purpose Forest Parks with Passive Defense Requirements (Case study of Tehran: Region no.4)

Amongst the most important issues ensuring the safety and security of citizens and reducing the crisis in cities, are practical and multi-purpose plans in which passive defense considerations and principles are observed. These plans reduce the severity and extent of damage and loss due to hazards. Forest parks are the type of urban recreation areas that with proper planning, provide space for recreation, cultural and educational activities, to meet the psychological needs and peace of society in normal conditions, and offer suitable space for temporary housing, warehousing, relief operations, and sustainable security in the time of emergencies and crisis. In this research, an attempt has been made to design forest parks in accordance with the objectives of passive defense, using plants and natural features and artificial elements, with the possibility of housing in emergency conditions. The purpose of this design is to utilize the urban green space and use the relief and housing plan in emergency situations to increase the ability to use green space in times of crisis and use places for safe keeping and storage of food and rescue equipment. This research is applied research in terms of descriptive-analytical nature and library studies, field observation and objective have been used to collect information. After conducting studies and investigating the factors effective in location assignment, and also implementing the colonial competitive algorithm in Matlab software, the Pasdaran district is identified as the most suitable location and marked on the google map software. Applying the results of the research and taking into account the general and defensive requirements, a park is designed using AUTOCAD software.
