چکیده مقاله :
Background and objective: Construction waste management is a critical concern for urban development, particularly in rapidly growing cities like Yazd, where improper disposal poses significant environmental and health risks. Identifying suitable locations for construction waste landfills, while considering environmental, social, and logistical criteria, is essential for sustainable urban planning. This study aimed to use Geographical Information Systems (GIS) and the Analytical Hierarchy Process (AHP) to identify the most suitable sites for construction waste disposal in Yazd, based on key criteria such as proximity to population centers, water resources, and transportation networks. Materials and methods: A comprehensive multi-criteria evaluation was conducted by integrating spatial data with expert opinions using GIS and AHP techniques. Several key factors, including proximity to population centers, water bodies, access networks, wind direction, and land use, were considered. A pair-wise comparison matrix was developed to assign relative weights to these factors based on their importance, and a suitability map was generated to identify the optimal landfill locations. The study area was then divided into different zones, categorized based on their level of suitability for waste disposal. Results and conclusion: The final land suitability map identified three main sites, with Site 1 (44.39 hectares in the northeast) emerging as the most suitable location for a new landfill, given its favorable wind direction, distance from population centers, and stable land features. Site 2 (21.17 hectares) and Site 3 (20.6 hectares) were also identified as viable alternatives. The analysis of existing waste disposal sites revealed that the site near Azadegan Road has better suitability, while the Faqih Khorasani Boulevard site was deemed unsuitable. The results demonstrate the efficacy of GIS and AHP in facilitating informed decision-making for sustainable waste management in urban areas.
