مكانيابي پهنه هاي مناسب براي بلند مرتبه سازي در مناطق كلان شهري با استفاده از سيستم اطلاعات جغرافيايي (مطالعه موردي: كلان‌ شهر اصفهان)

Given the rapid growth of urban population an‎d the limitations of horizontal development of cities, vertical development has been proposed as a solution for the exploitation of urban lan‎ds. However, high-rise construction, due to its physical, social, economic an‎d environmental consequences, requires careful planning an‎d scientific location based on numerous biological indicators an‎d legal criteria. High-rise construction, if implemented in a principled manner an‎d based on urban development criteria an‎d stan‎dards, can play an important role in spatial efficiency, reducing infrastructure costs, an‎d improving the quality of urban life. The city of Isfahan, as one of Iranʹs historical an‎d cultural metropolises, requires precise planning based on scientific principles to determine suitable areas for high-rise construction due to its specific physical, environmental, an‎d heritage conditions. The present study aims to identify an‎d locate suitable areas for high-rise construction in Isfahan metropolis an‎d uses a spatial analysis approach based on geographic information system. In this regard, the weighted linear average (WLC) multi-criteria decision-making model has been used as an integrated method for combining an‎d weighting the indicators. The research process included identifying an‎d selec‎ting indicators that affect the location of high-rise buildings using upstream documents, especially the criteria an‎d stan‎dards approved by the Supreme Council of Urban Planning an‎d Architecture of Iran. The indicators under study are divided into two general categories: natural an‎d human, an‎d nine sub-indicators include access an‎d passages, density, population, an‎d urban services in the human category; topography, slope an‎d slope angle, lan‎dscape, an‎d visibility, an‎d soil in the natural category. After preparing a classification map for the sub-indicators using quantitative data an‎d satellite images, a level code from 1 to 5 based on the classification in the maps was entered into the table as the score of each neighborhood for weighting. After normalizing an‎d weighting these indicators, using the WLC model, information related to the weight of the indicators was entered into the GIS environment an‎d the final zoning map was produced with two macro approaches for the entire city of Isfahan an‎d micro approaches, separated by urban areas, for the most suitable neighborhoods for high-rise development in the city of Isfahan. The research findings show that some neighborhoods in Isfahan city meet the optimal conditions for high-rise construction, which in a comprehensive analysis are mostly located in areas 14 an‎d 15 an‎d in the southwestern part of the city, an‎d in a detailed analysis, these neighborhoods are scattered across different regions. The results of this research can be used as a strategic tool by urban managers, planners, an‎d policymakers to develop high-rise buildings in Isfahan with a balanced, sustainable, an‎d evidence-based approach.
