Evaluation of green spaces of Hashtgerd new city from the perspective of emergency evacuation

Preparedness for an earthquake is one of the most important factors in reducing the fatalities caused by it; this preparedness has various aspects that can be designed with proper planning so that the city suffers the least damage in the moment of disasters such as an earthquake. Proper open and green spaces, in addition to improving the quality of daily life in cities, can increases the citychr('39')s rehabilitation capacity in earthquake-prone zones. In this study, the aim is to identify the important role of urban open spaces in rescue and emergency shelter after the earthquake, vulnerability of these spaces in the Hashtgerd new town, and their response to the population density.

The present research is applied and its method is descriptive-analytical. In this method, information was collected by reviewing documents, conducting field studies, and studying specialized sources. Access to green spaces, proportionality to population density, land use and distance from relief centers were selected and finally by quantitative content analysis and weighting of each of the indicators by AHP method in Expert Choice software and review of green spaces according to individual Indicators in GIS software, critical zone revealed.

During the article process, by examining the vulnerability of urban green spaces with the indicators of proximity to faults, proximity to relief centers, access to them, compatibility with surrounding land uses and population density, it is determined that only about 12% From the area of the city, which includes phases one, two, three and part of phase four, they are in a critical situation and very vulnerable. Instead, 69.23% of its area has low and very low vulnerability and 18.69% have moderate vulnerability.

Considering that 3.81% of the area of green spaces in the city is in a critical situation (which these sections are located in phases 1, 2, 3 and 4 of the city) for solution creating appropriate access and balanced distribution of green spaces throughout the city, increase their number and prevent the conversion of gardens and green spaces into residential lands, remove hazardous uses from the city limits, increase relief centers And the consolidation of soil and terracing of green spaces on the slope to prevent landslides following a possible earthquake can reduce the vulnerability of green spaces in Hashtgerd and provide safer conditions when evacuating and housing the earthquake victims.
