Evaluation of Ardabil City Carrying Capacity Using DPSIR Method and ELECTRE Model

Abstract

 In the modern view, argument about urban carrying capacity and spaces utilized due to urban development throughout the world has been considered. The increase in size and number of the cities, human activities such as land use change, high consumption of resources and emission of pollutants have left negative impacts on the function and structure of the urban ecosystems and have caused many problems for the circulation of materials and energy. The present study, by applied method and with the aim of studying carrying capacity of Ardebil City using the components of driving force, pressure, state, impact and response with multi-criteria decision model ELECTRE to prioritize the four- Regions districts of the Ardabil City by effective indicators in the form of 5 components discussed in the DPSIR method has been done. Collected information first, classified and categorized by DPSIR method, then by the means of utilizing Expert Choice weighted and ultimately by the implementation of ELECTRE model, the four- Regions districts of Ardabil City in terms of the presented indicators were prioritized. The results obtained from DPSIR method showed that, among the four- Regions districts of Ardabil City, driving force coefficient and then responding with 0/40 and 0/35 ratio have the greatest impact on the carrying capacity of the region. Also, the results of the prioritization of the ELECTRE model exhibit that regions 2 and 3 use the maximum capacity of the area according to the components used in DPSIR, and regions 1 and 4 are in the next priority.
