Title

THE ASSESSMENT OF PHYSICAL DEGRADATION THROUGH THE INTEGRATION OF TOPSIS AND AHP MODELS IN THE URBAN-RURAL ZONES (CASE STUDY: MARAVEH TAPPE CITY)

Pages

Abstract

 Historical and ancient zones of cities are a part of historic and cultural heritage of settlements. These zones are occasionally affected by PHYSICAL DEGRADATION and deterioration over timedue to lack of proper maintenance and performance. Thus, rehabilitation and proper maintenance, even renovation in some cases are essential for the survival of their physical structure and functional role. These challenges in rural areas are as strong as urban zones. The assessment of physical deterioration in these zones in order to select the best intervention pattern is one of the most important challenges facing the urban planners and managers...Therefore, it is necessary to develop strategies for proper prioritization and efficient intervention in the degrading zones.The first purpose of this study is recognizing the indicators of PHYSICAL DEGRADATION in urban and rural zones, and the second is designing the suitable pattern for assessing vulnerability and PHYSICAL DEGRADATION. Also, with the use of spatial analysis based on fuzzy logic instead of Boolean combinations, the study was able to process the ambiguous data and integrate it with TOPSIS. This process helped in detefinition of a model fot the assessment of the rate of PHYSICAL DEGRADATION in different zones. To test this model in field practice, Maraveh Tappe City was selected as pilot research sample. Results show that the entire urban zone is divided into four areas base on the degree of degradation, including appropriate urban zones, zones of intense PHYSICAL DEGRADATION (first priority for interventions), the relatively degraded areas (second priority) and areas in need of rehabilitation (third priority).
