Interpretive Structural Modelling of the Impact of Functional Dimensions of Urban Management on the Trends of Spatial Sprawl Yasuj City

Some factors such as the lack of strong urban management and lack of property control have prevented the urban body from expanding in a balanced way and has many adverse economic, physical and environmental consequences for cities. The aim of this study was to model the functional dimensions of urban management affecting the process of spatial dispersion in Yasuj. The research is applied in terms of purpose and descriptive-analytical in terms of nature and method. In the data preparation stage, the functional dimensions of urban management affecting the dispersal trend of Yasuj city were identified using the opinions of various experts through the Delphi method. For the Delphi team and the ISM team, 20 experts were selected by purposive sampling. Data analysis was performed by structural-interpretive modeling (ISM). The results showed that in terms of penetration power among the 16 identified indicators, the highest stimulus belonged to the agents monitoring the implementation of laws related to land use change and determining and monitoring the privacy and legal boundaries of the city with 16 and 15 penetration powers, respectively. The model of the present study also included 11 levels that the factor of monitoring the implementation of land use change rules (C2) was recognized as level eleven and the most effective factor. Based on the output of MicMac analysis; determining the legal boundaries of the city (C3), factors of construction supervision (C6), more access to municipal services (C1), monitoring the implementation of laws related to land use change (C2) are among the key independent and highly influential variables that affect the dispersal of Yasuj city. Therefore, urban management, as the main trustee in this field, should pay more attention to key independent components of physical performance.
